- 1 - B,714/5 DETERGENT COMPOSITIO~
.
This invention relates to detergent compositions which are particularly but not essentially, adapted for fabric washing, and more particularly to detergent compositions containing sodium perborate as a bleach component.
It is known to include sodium perborate in detergent co~positions as a bleach component, the perborate being in the form commonly known as the tetrahydrate, which has the empirical formula:
~aB02 H2Q2 3H2 While the stability of this material is adequate in compositions which contain, for example, sodium tripolyphosphate as a detergency builder, when this builder material is replaced wholly or in part with an alXalimetal aluminosilicate material or a mixture thereof with other builder materials, the stability of sodium perborate tetrahydrate is reduced, resulting in some cases in such ' be sufficiently stable to enable its use in detergent compositions, while the poor stability of the tetrahydrate in similar compositions may make its use less desirable.
The particle size of the perborate monohydrate is, when expressed in terms of aggregate size, to some extent independent of the speciEic surface area. Particle sizes of 100-1000 microns, most preferably 200-500 microns may be used in compositions according to the invention.
The detergent compositions of the invention neces-sarily contain a detergent active material. This may be a naturally derived detergent active material, such as soap, or a synthetic detergent active material selected from synthetic anionic, nonionic, amphoteric, zwitterionic or cationic detergent active materials or mixtures thereof.
Many suitable detergent active compounds are com-mercially available and are fully described in the liter-ature, for example in "Surface Active Agents and Detergents", Volumes I and II, by Schwartz, Perry and Berch.
The total level of the detergent active material is preferably between 6% and 40% by weight most preferably from about 10 to 25% by weight of the composition.
The synthetic anionic detergent compounds are usually water soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher aryl radicals. Examples of suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher (C8-C18) alcohols produced for example from tallow or coconut oil; sodium and ~'^.

- 2 - B.714/5 poor stability that such compositions have substantially no effective bleach capacity aftsr only a few months storage.
It is therefore an object of the present invention to provide a detergent composition containing a bleach componPnt and an alkalimetal aluminosilicate material as a detergency builder, in which the stability of the bleach component is adequate.
Thus, according to the invention there is provided a solid detergent composition containing at least a detergent active material and an alkalimetal aluminosilicate material as a detergency builder, characterized in that the composition further contains sodium perborate monohydrate in particulate form having a specific surface area of at least 5 m2/g, preferably more than about 7 m2/g.
The sodium perborate monohydrate used in the present invention has the empirical formula:
NaB02 . H202 While this is not strictly a monohydrate, but rather an anhydrate, this material is known commercially a~ the monohydrate and will be referred to ~hroughout this specification as the monohydrate. It should not be confused with any other hydrates of sodium perborate, having different empirical formulae. However, the present invention may make use of mixtures of the monohydrat~ and tetrahydrate. While it is observed, as expected, that the stability of sodium perborate tetrahydrate in aluminosilicate-containing compositions decreases with increasing specific surface area, we have surprisingly discovered that, in the case of the monohydrate, the stability increases with increasing specific surface area and that above a threshold of S m2/g, the monohydrate may _ 4 _ B.714/5 potassium alkyl (Cg-C20) benzene sulphonates, particularly sodium linear secondary alkyl (Cl0-Cl5) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived-from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty acid monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (Cg-Cl8) fatty alcohol-alkylene oxide, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydroxide; sodium and potassium salts of fatty acid amides of methyl taurine; alkane monosulphonates such as those derived by reacting alpha-olefins (C8 C20) with sodium bisulphite and thosederived by reacting para~fins with SO2 and Cl2 and then hydrolysing with a base to produce a random sulphonate, and olefin sulphonates, which term is used to describe the material made by reacting olefins, particularly Cl0-C20 alpha-olefins, with SO3 and then neutralising and hydrolysing the reaction product. The preferred anionic cletergent compounds are sodium (Cll-Cl5) alXyl benzene sulphonates and sodium (Cl6-Cl8) alXyl sulphates-Examples of suitable nonionic detergent compounds which may be used, preferably together with the anionic detergent compounds include in particular ~he reaction products of alkylene oxides, usually ethylene oxide, with alkyl (C6-C22) p~enols, generally 5 to 25 EO, ie 5 to 25 units of ethylene oxides per molecule the condensation products of aliphatic (C8-Cl8) primary or secondary linear or branched alcohols with ethylene oxide, generally 6 to 30 EO, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine. Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long _ 5 _ B.714/5 chain tertiary phosphine oxides and dialkyl sulphoxides.
Mixtures of the anionic detergent compounds with, for example, nonionic compounds may be used in the detergent compositions, particularly to provide controlled low sudsing properties. This is beneficial for compositions intended for use in suds-intolerant automatic washing machines. The presence of some nonionic detergent compounds in the compositions may also help to improve the solubility characteristics of the detergent powder.
Amounts of amphoteric or ~witterionic detergent compounds can also be used in the compositions of the invention but this is not normally desired due to their relatively high cost. If any amphoteric or zwitteri~nic detergent compounds are used it is generally in small amounts in compositions based on the much more commonly used synthetic anionic and nonionic detergent compounds. I
As stated above, soaps may also be used in the compositions of the in~ention, preferably at a level of less than 30% by weight. They are p~rticularly useful at low levels in binary (soap/anionic) or ternary mixtures together wlth nonionic or mixed synthetic anionic and nonionic detergent compounds, which have low sudsing properties. The soaps which are used are preferably the sodium, or less desirably potassium, salts of saturated or unsaturated C10-C24 fatty acids or mixtures thereof.
The amount of such soaps can be varied between about 0.5 and about 25% by weight, with lower amounts of about 0.5~
to about 5% being generally sufficient for lather control.
Amounts of soap between about 2% and about 20%, especially between about 5% and about 15%, are preferably used to give a beneficial effect on detergency. This is particularly valuable in compositions used in hard water when the soap - 6 - B.714/5 acts as a supplementary builder. In addition, we have found that the addition of soap helps to decrease the tendency of the compositions to form inorganic deposits in the wash, particularly where the composition contains a calcium ion precipitant material such as sodium carbonate or sodium orthop~osphate, for which purpose it is preferred to use about 2% to about 15~, especially about 2.5~ to about 10% by weight of soap in the composition. When soap is present, it is preferred that the total level of detergent actives, including the soap, lies between about 5% and about 40% by weight, most preferably between about 10~ and about 25% by weight.
The detergent compositions of the invention also necessarily contain an alXali metal aluminosilicate material as a detergency builder.
The aluminosilicate builder material is preferably crystalline or amorphous material having the general formula:
(M20~z-A1~03.(SiO2)y x H2 wherein M is sodium and/or potassiumr z is a number from 0.7 to 1.5, preferably about 1.0, y is a number from 0.8 ~o 6, preferably 1.3 to 4, and x is such that the moisture content is from 10% to 28~ by weight. While theoretically, at least for a pure crystalline material, the value of z should be not more than 1.0 and the value of y should be not less ~han 1.0, in practice, particularly in amorphous materials, impurities may occur resulting in the possibility that the values of z and y may vary within the above ranges. The preferred range of aluminosilicate is from 5% to 60% most preferably 15-50% on an anhydrous basis. The aluminosilicate preferably has a particle size o~ from 0.1 to 100 microns, ideally between 0.1 and 10 7 tD~i ~ 7 _ B.714/5 microns and a calcium ion exchange capacity of at least 200 mg.calcium carbonate/g. In a preferred embodiment, the ~ater-insoluble aluminosilicate ion exchang2 material has the formula:
Nal2(AlO25io2)l2xH2 wherein x is an integer of from 20 to 30, preferably about 27. This material is available commercially as Zeolite A.
The preferred level of the sodium perborate monohydrate ~measured as ~aBO2.H2O2) is 2 to 50%, most preferably 2 to 40% such as 4 to 30~.
The weight ratio of the aluminosilicate material to the perborate monohydrate is preferrably between 30:1 and 1:10, most preferably between 30:1 and 1:8, such as bet~een 12:1 and 1:2.
While the compositions of the invention may contain only the detergent active material(s), the aluminosilicate materials and the perborate monohydrate, other material~
may also be present in the compositions. Thus, the compositions may contain further detergency builder materials selected from:
~5 (a~ other calcium ion-exchange builder materials, (b) calcium sequesterant builder materials;
~c) precipitating builder materials; and ~d) mixtures thereof.
In particular, the compositions of the invention may contain a sequesterant builder material such as the sodium salt of nitrilotriacetic acid, or sodium tripolyphosphate.
When a further builder material is present, it may be prPsent at a level of less than 25% by weight.
~ 2~
~ 8 ~ B.714/5 ThP detergent compositions of the present invention may contain an activator for the perborate, particularly when the compositions are intended ~or washing fabrics at temperatures below about 60C.

(m) Carbonic acid esters, ~or example the sodium salts of p-(ethoxycarbonyloxy)-bensoic acid and p-(propoxy-carbonyloxy)-benzenesulphonic acid;
~.2~
- 10 - B.714/5 (n) Acyloxy-~N,~ )polyacyl malonamides, such as -acetoxy(N,~l)diacetyl malonamide.
The ~-diacylated and ~,~'-polyacylatedamines mentioned under (a) are of special interest, particularly ~,~,~',N' tetra-acetyl-ethylenediamine (TAFD).
Th~ ratio by weight of the perborate to the activator may be about 20:1 to about 1:1, preferably about 10:1 to about 2:1, although weight ratios outside these limits are not excluded. Whilst the ~mount of the bleach system, ie perborate and activator may be varied between about 5% and about 35~ by weight of the detergent compositions, it is especially preferred to use about 6% to about 30% of the ingredients forming the bleach system. Thus, when an activator is present, the preferred level of the perborate monohydrate in the composition is between 2% and 30% by weight, most preferably b2tween about 5.0% and about 27% by weight, while the preferred level of the activator is between about 0.5% and about 10%, most preferably between about 1.0~ and about 8.0% by weight.
In the case of ~AED it is preferred to use the activator in granular form, preferably wherein the 25 activator is finely divided as described in GB 2 053 998.
Specifically, it is preferred to have an activator of an average particle size of less than 150 micrometers, which gives significant improvement in bleach efficiency. The sedimentation losses, when using an activator with an average particle size of less than 150/um, are substantially decreased. Even better bleach performance is obtained if the average particle size of the activator is less than 100 /um. On the other hand, the activator may have a certain amount of particles of a size greater than 150 /um, but it should not contain more than 5~ by weight of particles greater than 300 /um, and not more than 20%
. .
~2~ 5 ~ B.714/5 by weight of particles greater than 200 /um, preferably greater than 150 /um. It is to be understood that these particle sizes refer to the activator present in the granules, and not to the granules themselves. In a suitable such granule, the major part of the yranule~ range from 100 to 2000 /um, preferably 250 to 1000 /um. Up to 5% by weight of granules with a particle size o greater than 1700 /um and up to 10% by weight of granules less than 250 /um is tolerable. The granules incorporating the activator, preferably in this finely-divided fol~, may be obtained by granulating a suitable inorganic or organic carrier material with activator particles of the required size. The granules can be subsequently dried, if required. Basically, any granulation process is applicable, as long as the g~anule contains the activator, and as long as the other materials present in the granule do not negatively affect the activator.
It is particularly preferred to include in the detergent compositions a stabiliser for the bleach system for example ethylene diamine tetramethylene phosphonate and diethylene triamine pentamethylene phosphonate. These activators can be used in acid or salts form, especially in calcium, magnesium, zinc or aluminium salt form, as described in GB 2 048 930. The stabiliser m~y be present at a level of up to about 1% by weight, preferably between about 0.1% and about 0.5% by weight.
Apart from the components already mentioned, the detergent compositions of the invention can contain any of the conventional additives in the amounts in which such materials are normally employed in fabric washing detergent compositions. Examples of these additives include other bleach materials such as peroxyacids and photobleaches, ~ather boosters such as alkanolamides, particularly the monoethanolamides derived from palm kernel fatty acids and (D5 - 12 - B.714/5 coconut fatty acids, lather depressants such as alkyl phosphates and silicates, anti-redeposition agents such as sodium carboxymethylcellulose and alkyl or substituted alkyl cellulose, ethers other stabilisers such as ethylenediamine tetraacetic acid r fabric softening agents, inorganic salts such as sodium sulphate, and, usually present in very minor amounts, fluorescent agents, perfumes, enzymes such as proteases and amylases, germicides and colourants. In particular, compositions according to the invention may include the salt of an alkyl phosphoric acid as suds-suppressant and a wax as hydrophobic material as disclosed in DOS 2 701 664.
It is desirable to include one or more antideposition agents in the detergent compositions of the invention, to decrease a tendency to form inorganic deposits on washed fabrics. The amount of any such antideposition agent is normally from about 0.1% to about 5% by weight, preferably from about 0.2~ to about 2.5~ by weight of the composition.
The preferred antideposition agents are anionic poly-electrolytes, especially pol~meric aliphatic carboxylates, or organic phosphonatesO
It may be desir~ble to include in the compositions an amount of an alkali metal silicate, particularly sodium ortho-, meta- or preferably neutral or alkaline silicate.
The presence of such alkali metal silicates at levels of at least about 1~, and preferably from about 5% to about 15%
by weight of the compositions, is advantageous in decseasing the corrosion of metal parts in washing machines, besidss giving processing benefits and generally improved powder properties. The more highly alkaline ortho- and meta-silicates would normally only be used at lower amounts within this range, in admi~ture with the neutral or al~aline silicates.
- 13 - B.714/5 The compositions of the invention are required to be alkaline, but not too strongly alkaline as this could result in fabric damage and also be ha~ardous for domestic usage. In practice the compositons should give a pH of from about 8.5 to about 11 in use in aqueous wash solution.
It is preferred in particular for domestic products to have a pH of from about 9.0 to about lO.S as lower p~s tend to be less effective for optimum detergency building, and more highly alkaline products can be hazardous if misused. ~he p~ is measured at the lowest normal usage concentration of 0.1~ w/v of the product in water of 12~H (ca), (French permanent hardness, calcium only) at 50C so that a satisfactory degree of alkalinity can be assured in use at all normal product concentrations.
The detergent compositions of the invention should be in free-flowing particul~te, eg powdered or granular form, and can be produced by any of the techniques commonly employed in the manufacture of such washing compositions, but preferably by slurry making and spray drying processes to form a detergent base powder to which the perborate monohydrate is added. It is preferred that the process used to form the compositions should result in a product having a moisture content of from about 4% to about 10% by weight.
The invention will now be illustrated by the following non-limiting examples:
Commercially available sources of sodium perborate monohydrate having different specific surface areas were incorporated in base compositions to give an overall average available oxygen of 2.56%. The compositions comprised approximately:
- 14 - B.714/5 Anionic detergent activel12.0 ~onionic detergent active25.5 Soap3 9.2 Zeolite A (calculated as anhydrous) 33.0%
Sodium silicate4 14.7~
Sodium perborate monohydrate 16.0%
(calculated as ~aBO2.H202) Water and minor ingxedients balance to 100%
Notes:
1. ~he anionic detergent active was an alXyl benzene sulphonate with an average alkyl chain length of 11-13 and an average moledular wei~ht of 345.
2. The nonionic detergent active was Do~anol-45 11 EO
(an ethoxylated alkanol available from Shell)
It is therefore an object of the present invention to provide a detergent composition containing a bleach componPnt and an alkalimetal aluminosilicate material as a detergency builder, in which the stability of the bleach component is adequate.
Thus, according to the invention there is provided a solid detergent composition containing at least a detergent active material and an alkalimetal aluminosilicate material as a detergency builder, characterized in that the composition further contains sodium perborate monohydrate in particulate form having a specific surface area of at least 5 m2/g, preferably more than about 7 m2/g.
The sodium perborate monohydrate used in the present invention has the empirical formula:
NaB02 . H202 While this is not strictly a monohydrate, but rather an anhydrate, this material is known commercially a~ the monohydrate and will be referred to ~hroughout this specification as the monohydrate. It should not be confused with any other hydrates of sodium perborate, having different empirical formulae. However, the present invention may make use of mixtures of the monohydrat~ and tetrahydrate. While it is observed, as expected, that the stability of sodium perborate tetrahydrate in aluminosilicate-containing compositions decreases with increasing specific surface area, we have surprisingly discovered that, in the case of the monohydrate, the stability increases with increasing specific surface area and that above a threshold of S m2/g, the monohydrate may _ 4 _ B.714/5 potassium alkyl (Cg-C20) benzene sulphonates, particularly sodium linear secondary alkyl (Cl0-Cl5) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived-from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty acid monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (Cg-Cl8) fatty alcohol-alkylene oxide, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydroxide; sodium and potassium salts of fatty acid amides of methyl taurine; alkane monosulphonates such as those derived by reacting alpha-olefins (C8 C20) with sodium bisulphite and thosederived by reacting para~fins with SO2 and Cl2 and then hydrolysing with a base to produce a random sulphonate, and olefin sulphonates, which term is used to describe the material made by reacting olefins, particularly Cl0-C20 alpha-olefins, with SO3 and then neutralising and hydrolysing the reaction product. The preferred anionic cletergent compounds are sodium (Cll-Cl5) alXyl benzene sulphonates and sodium (Cl6-Cl8) alXyl sulphates-Examples of suitable nonionic detergent compounds which may be used, preferably together with the anionic detergent compounds include in particular ~he reaction products of alkylene oxides, usually ethylene oxide, with alkyl (C6-C22) p~enols, generally 5 to 25 EO, ie 5 to 25 units of ethylene oxides per molecule the condensation products of aliphatic (C8-Cl8) primary or secondary linear or branched alcohols with ethylene oxide, generally 6 to 30 EO, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine. Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long _ 5 _ B.714/5 chain tertiary phosphine oxides and dialkyl sulphoxides.
Mixtures of the anionic detergent compounds with, for example, nonionic compounds may be used in the detergent compositions, particularly to provide controlled low sudsing properties. This is beneficial for compositions intended for use in suds-intolerant automatic washing machines. The presence of some nonionic detergent compounds in the compositions may also help to improve the solubility characteristics of the detergent powder.
Amounts of amphoteric or ~witterionic detergent compounds can also be used in the compositions of the invention but this is not normally desired due to their relatively high cost. If any amphoteric or zwitteri~nic detergent compounds are used it is generally in small amounts in compositions based on the much more commonly used synthetic anionic and nonionic detergent compounds. I
As stated above, soaps may also be used in the compositions of the in~ention, preferably at a level of less than 30% by weight. They are p~rticularly useful at low levels in binary (soap/anionic) or ternary mixtures together wlth nonionic or mixed synthetic anionic and nonionic detergent compounds, which have low sudsing properties. The soaps which are used are preferably the sodium, or less desirably potassium, salts of saturated or unsaturated C10-C24 fatty acids or mixtures thereof.
The amount of such soaps can be varied between about 0.5 and about 25% by weight, with lower amounts of about 0.5~
to about 5% being generally sufficient for lather control.
Amounts of soap between about 2% and about 20%, especially between about 5% and about 15%, are preferably used to give a beneficial effect on detergency. This is particularly valuable in compositions used in hard water when the soap - 6 - B.714/5 acts as a supplementary builder. In addition, we have found that the addition of soap helps to decrease the tendency of the compositions to form inorganic deposits in the wash, particularly where the composition contains a calcium ion precipitant material such as sodium carbonate or sodium orthop~osphate, for which purpose it is preferred to use about 2% to about 15~, especially about 2.5~ to about 10% by weight of soap in the composition. When soap is present, it is preferred that the total level of detergent actives, including the soap, lies between about 5% and about 40% by weight, most preferably between about 10~ and about 25% by weight.
The detergent compositions of the invention also necessarily contain an alXali metal aluminosilicate material as a detergency builder.
The aluminosilicate builder material is preferably crystalline or amorphous material having the general formula:
(M20~z-A1~03.(SiO2)y x H2 wherein M is sodium and/or potassiumr z is a number from 0.7 to 1.5, preferably about 1.0, y is a number from 0.8 ~o 6, preferably 1.3 to 4, and x is such that the moisture content is from 10% to 28~ by weight. While theoretically, at least for a pure crystalline material, the value of z should be not more than 1.0 and the value of y should be not less ~han 1.0, in practice, particularly in amorphous materials, impurities may occur resulting in the possibility that the values of z and y may vary within the above ranges. The preferred range of aluminosilicate is from 5% to 60% most preferably 15-50% on an anhydrous basis. The aluminosilicate preferably has a particle size o~ from 0.1 to 100 microns, ideally between 0.1 and 10 7 tD~i ~ 7 _ B.714/5 microns and a calcium ion exchange capacity of at least 200 mg.calcium carbonate/g. In a preferred embodiment, the ~ater-insoluble aluminosilicate ion exchang2 material has the formula:
Nal2(AlO25io2)l2xH2 wherein x is an integer of from 20 to 30, preferably about 27. This material is available commercially as Zeolite A.
The preferred level of the sodium perborate monohydrate ~measured as ~aBO2.H2O2) is 2 to 50%, most preferably 2 to 40% such as 4 to 30~.
The weight ratio of the aluminosilicate material to the perborate monohydrate is preferrably between 30:1 and 1:10, most preferably between 30:1 and 1:8, such as bet~een 12:1 and 1:2.
While the compositions of the invention may contain only the detergent active material(s), the aluminosilicate materials and the perborate monohydrate, other material~
may also be present in the compositions. Thus, the compositions may contain further detergency builder materials selected from:
~5 (a~ other calcium ion-exchange builder materials, (b) calcium sequesterant builder materials;
~c) precipitating builder materials; and ~d) mixtures thereof.
In particular, the compositions of the invention may contain a sequesterant builder material such as the sodium salt of nitrilotriacetic acid, or sodium tripolyphosphate.
When a further builder material is present, it may be prPsent at a level of less than 25% by weight.
~ 2~
~ 8 ~ B.714/5 ThP detergent compositions of the present invention may contain an activator for the perborate, particularly when the compositions are intended ~or washing fabrics at temperatures below about 60C.

(m) Carbonic acid esters, ~or example the sodium salts of p-(ethoxycarbonyloxy)-bensoic acid and p-(propoxy-carbonyloxy)-benzenesulphonic acid;
~.2~
- 10 - B.714/5 (n) Acyloxy-~N,~ )polyacyl malonamides, such as -acetoxy(N,~l)diacetyl malonamide.
The ~-diacylated and ~,~'-polyacylatedamines mentioned under (a) are of special interest, particularly ~,~,~',N' tetra-acetyl-ethylenediamine (TAFD).
Th~ ratio by weight of the perborate to the activator may be about 20:1 to about 1:1, preferably about 10:1 to about 2:1, although weight ratios outside these limits are not excluded. Whilst the ~mount of the bleach system, ie perborate and activator may be varied between about 5% and about 35~ by weight of the detergent compositions, it is especially preferred to use about 6% to about 30% of the ingredients forming the bleach system. Thus, when an activator is present, the preferred level of the perborate monohydrate in the composition is between 2% and 30% by weight, most preferably b2tween about 5.0% and about 27% by weight, while the preferred level of the activator is between about 0.5% and about 10%, most preferably between about 1.0~ and about 8.0% by weight.
In the case of ~AED it is preferred to use the activator in granular form, preferably wherein the 25 activator is finely divided as described in GB 2 053 998.
Specifically, it is preferred to have an activator of an average particle size of less than 150 micrometers, which gives significant improvement in bleach efficiency. The sedimentation losses, when using an activator with an average particle size of less than 150/um, are substantially decreased. Even better bleach performance is obtained if the average particle size of the activator is less than 100 /um. On the other hand, the activator may have a certain amount of particles of a size greater than 150 /um, but it should not contain more than 5~ by weight of particles greater than 300 /um, and not more than 20%
. .
~2~ 5 ~ B.714/5 by weight of particles greater than 200 /um, preferably greater than 150 /um. It is to be understood that these particle sizes refer to the activator present in the granules, and not to the granules themselves. In a suitable such granule, the major part of the yranule~ range from 100 to 2000 /um, preferably 250 to 1000 /um. Up to 5% by weight of granules with a particle size o greater than 1700 /um and up to 10% by weight of granules less than 250 /um is tolerable. The granules incorporating the activator, preferably in this finely-divided fol~, may be obtained by granulating a suitable inorganic or organic carrier material with activator particles of the required size. The granules can be subsequently dried, if required. Basically, any granulation process is applicable, as long as the g~anule contains the activator, and as long as the other materials present in the granule do not negatively affect the activator.
It is particularly preferred to include in the detergent compositions a stabiliser for the bleach system for example ethylene diamine tetramethylene phosphonate and diethylene triamine pentamethylene phosphonate. These activators can be used in acid or salts form, especially in calcium, magnesium, zinc or aluminium salt form, as described in GB 2 048 930. The stabiliser m~y be present at a level of up to about 1% by weight, preferably between about 0.1% and about 0.5% by weight.
Apart from the components already mentioned, the detergent compositions of the invention can contain any of the conventional additives in the amounts in which such materials are normally employed in fabric washing detergent compositions. Examples of these additives include other bleach materials such as peroxyacids and photobleaches, ~ather boosters such as alkanolamides, particularly the monoethanolamides derived from palm kernel fatty acids and (D5 - 12 - B.714/5 coconut fatty acids, lather depressants such as alkyl phosphates and silicates, anti-redeposition agents such as sodium carboxymethylcellulose and alkyl or substituted alkyl cellulose, ethers other stabilisers such as ethylenediamine tetraacetic acid r fabric softening agents, inorganic salts such as sodium sulphate, and, usually present in very minor amounts, fluorescent agents, perfumes, enzymes such as proteases and amylases, germicides and colourants. In particular, compositions according to the invention may include the salt of an alkyl phosphoric acid as suds-suppressant and a wax as hydrophobic material as disclosed in DOS 2 701 664.
It is desirable to include one or more antideposition agents in the detergent compositions of the invention, to decrease a tendency to form inorganic deposits on washed fabrics. The amount of any such antideposition agent is normally from about 0.1% to about 5% by weight, preferably from about 0.2~ to about 2.5~ by weight of the composition.
The preferred antideposition agents are anionic poly-electrolytes, especially pol~meric aliphatic carboxylates, or organic phosphonatesO
It may be desir~ble to include in the compositions an amount of an alkali metal silicate, particularly sodium ortho-, meta- or preferably neutral or alkaline silicate.
The presence of such alkali metal silicates at levels of at least about 1~, and preferably from about 5% to about 15%
by weight of the compositions, is advantageous in decseasing the corrosion of metal parts in washing machines, besidss giving processing benefits and generally improved powder properties. The more highly alkaline ortho- and meta-silicates would normally only be used at lower amounts within this range, in admi~ture with the neutral or al~aline silicates.
- 13 - B.714/5 The compositions of the invention are required to be alkaline, but not too strongly alkaline as this could result in fabric damage and also be ha~ardous for domestic usage. In practice the compositons should give a pH of from about 8.5 to about 11 in use in aqueous wash solution.
It is preferred in particular for domestic products to have a pH of from about 9.0 to about lO.S as lower p~s tend to be less effective for optimum detergency building, and more highly alkaline products can be hazardous if misused. ~he p~ is measured at the lowest normal usage concentration of 0.1~ w/v of the product in water of 12~H (ca), (French permanent hardness, calcium only) at 50C so that a satisfactory degree of alkalinity can be assured in use at all normal product concentrations.
The detergent compositions of the invention should be in free-flowing particul~te, eg powdered or granular form, and can be produced by any of the techniques commonly employed in the manufacture of such washing compositions, but preferably by slurry making and spray drying processes to form a detergent base powder to which the perborate monohydrate is added. It is preferred that the process used to form the compositions should result in a product having a moisture content of from about 4% to about 10% by weight.
The invention will now be illustrated by the following non-limiting examples:
Commercially available sources of sodium perborate monohydrate having different specific surface areas were incorporated in base compositions to give an overall average available oxygen of 2.56%. The compositions comprised approximately:

Notes:
1. ~he anionic detergent active was an alXyl benzene sulphonate with an average alkyl chain length of 11-13 and an average moledular wei~ht of 345.
2. The nonionic detergent active was Do~anol-45 11 EO
(an ethoxylated alkanol available from Shell)

4. The sodium silicate had a ~a20:SiO2 molar ratio of 1:1.6 Each composition was stored at 37C in a sealed glass bottle. When the composition had been stored for various periods between 2 and 12 weeks, the percentage available oxygen was assessed and used to calculate the rate constant for the decomposition of the perborate monohydrate as an indication of its stability. In the following Table I, the rat~ constant is shown against the specific surface area as measured by gas adsorption. For comparison purposes th~
rate constants obtained with similar compositions containing perborate tetrahydrate (at the same available oxygen level) are also shown.

Commercially available perborate monohydrate and perborate tetrahydrate (included for compari,son purposes) were incorporated into a base powder at a level equivalent to 1.76~ average available oxygen. The compositions were stored in sealed glass bottl~s or laminated packs under identical conditions (37C and 70% relative humidity).

The composition was prepared by spray drying a slurry of the anionic material, soap, silicate, sulphate and zeolite, post-dosing the remaining ingredients with the exception of the nonionic active and the succinate and subsequently granulating using a mixture of the nonionic active and the succinate as a binder.
The composition was stored in wax-laminated packs for 12 weeks at 37~C and 70% RH. After that time it was found *.hat 7% of the perborate monohydrate had decomposed and that the composition was still in the form of a fr~e flowing, non-lumpy crisp powder.
In a parallel experiment the perborate monohydrate was replaced with 25~ perborate tetrahydrate (the level of sodium sulphate being reduc~d to compensate). After the sam~ storage test 77% of the perborate tetrahydrate was found to have decomposed and the composition was in the form of a creepy, partly-lumpy soft powder.
