Description

AQUEOUS ALKALINE LIQUID DETERGENT COMPOSITION
The invention relates to built liquid detergent compositions. More in particular the invention relates to aqueous alkaline built liquid detergent compositions with improved rheologic properties.
Aqueous alkaline built liquid detergent compositions for use in fabric- or dishwashing machines are well Xnown. They are often considered to be more convenient to the user than the equivalent dry powdered or particulate products, as they are easier to dose, dissolve more readily, are non-dusting and usually occupy less storage space. Their formulation, however, is difficult since, on the one hand, considerable quantities of builder salts and alkaline agents should be incorporated to provide consumer-sa~isfactory detergency and, on the other hand, liquid products should be stable under a wide range of storage conditions and should have good pourability for consumer convenience.

2~
In the prior art the problem of incorporating adequate quantities of e.g. inorganic builder salts in a liquid detergent has been approached by providing liquid suspending media, which are able to support the undissolved part of the builder salt in the liquid in a semi-permanent way.
Although by internal or external structuring it has been possible to formulate liquid media capable of suspending adequate amounts of such undissolved or less soluble builders, hitherto it has proved difficult to formulate compositions of high alkalinity, which results from the use of alkaline builder salts or alkaline agents, such as silicates or ~2~ C 8~3 (R) sodium hydroxide, without a very negative effect on the viscosity behaviour and physical or chemical stability.
Accordingly it is an object of ~he invention to provide stable suspending built liquid detergent compositions of high alkalinity, which have a good pourability and viscosity behaviour.
It is a further object of the present invention to provide such compositions in which the surface-active system is primarily based on nonionic detergents.
In the German Patent Application No. 3.006.333 such alkaline liquid detergent composition is disclosed comprising a nonionic detergent and a suspending system on the basis of a combination of sodium poly-acrylate and modified polyacrylic acid. Tt ~as observed that compositions formulated according to the above disclosure without careful selection of the nonionic detergent in general showed unacceptably high viscosity and therefore poor pourability.
It has now been found that a highly alkaline liquid detergent composition can be formulated which comprises considerable levels of detergency builders and alkaline agents, comprising an alkoxylated fatty alcohol nonionic detergent or mixture of such nonionic detergents having an over-all ratio between the number of ethylene-oxide units and propylene- and/or butylene oxide units of less than 9, and an essentially single structuring agent of the cross-linked polyacrylate type.
By way of the invention compositions are obtained which combine the advantages of high alkalinity, stability, good viscosity and pourability and easy formulating.
C ~23 (R) ~2~15~
Accordingly, the present invention provides an alkaline built liquid detergent composition which comprises in an aqueous medium:
S (a) at least 2% by weight of an alkoxylated fatty alcohol nonionic detergent or mixture thereof having in the alkylene oxide radical an over-all ratio between the number of ethylene-oxide units and the propylene- and/or butylene-oxide units of less than 9;
(b) from 2 to 30% by weight of an alkaline agent;
(c) from S to 35~ by weight of a detergency buildQr;
and (d) from 0.1 to 1.0~ by weight of an essentially single structuring polymeric agent; the composition having a pH equal to or above 11.
An essential feature of the present invention is the specific selection of the nonionic detergent, which is of the fatty alcohol type being condensed with a mixture of ethylene-oxide and propylene-oxide and/or butylene-oxide. It is necessary to select the alkoxylated fatty alcohol or mixture thereof such that the over-all ratio between the number of ethylene-oxide units and the propylene~ and/or butylene-oxide units is below 9, preferably below 2.5 or even 1.8.
The term "over-all ratio" refers to the fact that either a single alXoxylated alcohol may be used having in its alkylene-oxide radical a suitable ratio of ethylene-oxide to propylene- and/or butylene-oxide units or a mixture of alkoxylated alcohols may be used having a suitable ratio only on an average.
; The nonionic detergent is normally present in an amount of at least 2% and in particular of at least 5~
by weight, the amount preferably ranging from 5 to 15%
by weight of the total composition.
C 823 (R) Nonionic detergents for use in compositions of the present invention can be readily obtained commercially, such at e.g. those sold under the trade names Lutensol LF 400 to 1300 ~ex BASF AG~ and Plurafac RA 30 to 343 (ex Produits Chimiques Ugine-Kuhlmann) The nonionic detergent can be used as sole detergent but other detergent-active ingredients, such as e.g.
the water-soluble anionic sulphate or sulp~.onate detergents, can be tolerated provided their amount does not exceed 5% by weight, preferably 3% by weight or even 1~ by weight of the total composition.
The alkaline agent is in general present in an amount of from 2% to 30% by weight, preferably 10 to 25~ by waight of the total composition. Examples of suitable agents are the alkalimetal hydroxides and sillcates, such as alkalimetal orthosilicates, metasilicates and disilicates, sodium meta-silicate being preferred.
Also mixtures of alkaline agents may be used, such as a combination oE sodium silicate and sodium hydroxide.
The compositions of the invention contain 5% to 35%, in particular 10~ to 30% and preferably 10~ to 25~ by weight of a detergency builder. Typical examples of suitable detergency builders are the phosphate buil-ders such as the alkalimetal salts of triphosphoric acid, pyrophosphoric acid, orthophosphoric acid, polymetaphosphoric acid and mixtures thereof. Sodium and potassium triphosphates are preferred. Other suitable builders include carbonates, zeolites and organic builders such as citrates and polycarboxylates such as nitrilotriacetate, and mixtures thereof.
The present compositions are e ternally structured and C 823 ~R) ~2'fl ~
for this purpose they contain an essentially single structuring or thickening polymeric a~ent. Suitable agents are found among the alkali-stable polymers.
Especially suitable are the water-soluble polymers of acrylic acid, cross-linked with about 1% of a poly-allyl ether of sucrose having an average o~ about 5.8 allyl groups for each sucrose molecule, the polymer having a molecular weight in excess of 1.000.000.
Examples of such polymers are Carbopol 934, 940 and 941. Carbopol is the Registered Trademark of B.F.
Goodrich Co. Ltd., the manufacturers o~ these polymers. The preferred polymer is Carbopol 941.
Depending on the viscosity which is desired they may be included in the range of from 0.1% to 1% by weight, but preferably their amount varies from 0.2% to 0.8 by weight, and in particular from 0.2 to 0.6% by weight of the total composition.
The liquid detergent composition of the invention may ~urther contain any of the adjuvants normally used in fabric-washing detergent compositions, e.g. seques-tering agents such as ethylenediaminetetraacetate and diethylenetetraamine methylene phosphoric acid, soil-suspending and anti-redeposition agents such as carboxymethylcellulose, polyvinylpyrrolidone and the maleic anhydride/vinylmethylether copolymer, fluores-cent agents; hydrotropes; conditioning agents; lather boosters, perfumes, ~ermicides and colourants.
Further the addition of lather-depressors such as liquid polysiloxane anti-foam compounds; alkaline stable enzymes, bleaches, such as e.g. sodium sulphite, and potassium dichlorocyanurate, may be necessary or desirable to formulate a complete heavy-duty detergent composition suitable for use in machinewashing operations. These ingredients can be employed in the liquid detergent without the risk of undue ~2195~0 C ~Z3 (R) decomposition during storage, especially if a proper protective coating is applied.
Compositions of the present invention normally have viscosities within the range of 0.3 to 3.0 Pa.s (at 20~C and 20 sec~l.), in particular within the range of 0.5 to 3.0 Pa.s and preferably within the range of 0.6-1.2 Pa.s.
Compositions of the present invention are especially advantageous having pH-values within the high alkaline region, in particular values equal to or above 11, but preferred are pH-values above 12 or even above 13.
The invention will be further illustrated in the following examples. All percentages used therein are by weight unless otherwise specified.
