JOINT RESEARCH AGREEMENT
The disclosure and claims herein were made as a result of activities undertaken within the scope of a joint research agreement in effect on or before the date the claimed invention was made between Rhône-Poulenc Chimie and Unilever U.K. Central Resources Limited.
A subject-matter of the present invention is a cleaning or rinsing composition intended for the treatment of industrial, domestic or communal hard surfaces, in particular of glass, window, ceramic, tiling, hard organic polymer, metal or wood type and the like, targeted at conferring on the latter hydrophilic properties and properties of protection (corrosion resistance) of glass, of dishes and of designs by washing media during repeated washing operations in an automatic dishwasher.
A more particular subject-matter of the invention is a cleaning composition intended for the treatment of a hard surface which is capable of conferring persistent hydrophilic properties on the latter, so as to prevent the subsequent presence of marks due in particular to the drying of drops of water deposited on said surface.
Commercial detergent formulations make it possible to efficiently clean industrial, domestic or communal hard surfaces. They are generally composed of an aqueous solution of surfactants, in particular of nonionic and anionic surfactants, of alcohol(s), in order to facilitate drying, and optionally of sequestering agents and of bases, in order to adjust the pH. A significant failing in these detergent formulations is that subsequent contact of the hard surface with water can result in the presence of marks during drying. This contact with water after application of detergent can originate, for example, from rainwater, in the case of windows, from mains water on bathroom tiling, or from rinsing water when the cleaning requires rinsing. It can also originate from the drying of the dishes in the open air, in the case of detergent formulae for cleaning dishes by hand, or from the drying of dishes in an automatic device when the detergent is intended for a dishwasher. In the case of the cleaning of dishes in an automatic device, said formula can either be used in the cleaning cycle (detergent formula) or during the rinsing (rinsing liquid).
The presence of marks or stains left on the hard surfaces by the water coming into contact with the latter is due to the phenomenon of contraction of the water drops on contact with the hard surface, which, during subsequent drying, leave marks on the surface which reproduce the original shapes and sizes of the drops.
Until now, no satisfactory solution to this problem existed.
To solve the problem posed by the retraction and the drying of the drops of water, the solution consists in increasing the hydrophilicity of the surface in order to obtain a contact angle between the hard surface to be treated and the drop of water which is as small as possible.
The studies of the Inventors which have led to the present invention have made it possible to determine that this problem can be solved in an efficient and lasting way by incorporating, in conventional cleaning compositions for hard surfaces, a water-soluble or water-dispersible organic polymer compound having both a function of interaction with the surface to be treated and a function conferring a hydrophilic nature on this surface.
A first subject-matter of the invention is a cleaning or rinsing composition comprising at least one water-soluble or water-dispersible copolymer comprising, in the form of polymerized units:
    • (a) at least one monomer compound of general formula I:
Figure USRE044058-20130312-C00002
      • in which
      • R1 is a hydrogen atom or a methyl or ethyl group;
      • R2, R3, R4, R5 and R6, which are identical or different, are linear or branched C1-C6, preferably C1-C4, alkyl, hydroxyalkyl or aminoalkyl groups;
      • m is an integer from 0 to 10, preferably from 0 to 2;
      • n is an integer from 1 to 6, preferably 2 to 4;
      • Z represents a —C(O)O— or —C(O)NH— group or an oxygen atom;
      • A represents a (CH2)p group, p being an integer from 1 to 6, preferably from 2 to 4;
      • B represents a linear or branched C2-C12, advantageously C3-C6, polymethylene chain optionally interrupted by one or more heteroatoms or heterogroups, in particular O or NH, and optionally substituted by one or more hydroxyl or amino groups, preferably hydroxyl groups;
      • X, which are identical or different, represent counterions;
    • (b) at least one hydrophilic monomer carrying a functional group with an acidic nature which is copolymerizable with (a) and which is capable of being ionized in the application medium;
    • (c) optionally at least one monomer compound with ethylenic unsaturation with a neutral charge which is copolymerizable with (a) and (b), preferably a hydrophilic monomer compound with ethylenic unsaturation with a neutral charge, carrying one or more hydrophilic groups, which is copolymerizable with (a) and (b).
The monomer (a) can be prepared, for example, according to the following reaction schemes:
Figure USRE044058-20130312-C00003
Figure USRE044058-20130312-C00004
Figure USRE044058-20130312-C00005
The monomer (a) confers, on the copolymer, characteristics of interaction with the surface to be treated, making possible in particular anchoring of the copolymer to this surface.
The monomer (b) and optionally the monomer (c) confers hydrophilic characteristics on the copolymer which, after anchoring of the copolymer to the surface to be treated, are passed on to the surface.
This property of rendering the surface hydrophilic furthermore makes it possible to reduce the formation of condensation on the surface; this advantage can be made use of in cleaning formulae for windows and mirrors, in particular in bathrooms.
The copolymer according to the invention advantageously exhibits a molecular mass of at least 1000, advantageously of at least 10,000; it can range up to 20,000,000, advantageously up to 10,000,000.
Except when otherwise indicated, when the term molecular mass is used, it will refer to the weight-average molecular mass, expressed in g/mol. The latter can be determined by aqueous gel permeation chromatography (GPC) or measurement of the intrinsic viscosity in a 1N NaNO3 solution at 30° C.
The copolymer is preferably a random copolymer.
Preferably, in the general formula (I) of the monomer (a),
    • Z represents C(O)O, C(O)NH or O, very preferably C(O)NH;
    • n is equal to 2 or 3, very particularly 3;
    • m ranges from 0 to 2 and is preferably equal to 0 or 1, very particularly to 0;
    • B represents

      • R1 to R6, which are identical or different, represent a methyl or ethyl group.
The preferred monomer (a) is Diquat of following formula:

Other particularly advantageous monomers (a) are:

Mention may be made, among the monomers (c), of acrylamide, vinyl alcohol, C1-C4 alkyl esters of acrylic acid and of methacrylic acid, C1-C4 hydroxyalkyl esters of acrylic acid and of methacrylic acid, in particular ethylene glycol and propylene glycol acrylate and methacrylate, polyalkoxylated esters of acrylic acid and of methacrylic acid, in particular the polyethylene glycol and polypropylene glycol esters, esters of acrylic acid or of methacrylic acid and of polyethylene glycol or polypropylene glycol C1-C25 monoalkyl ethers, vinyl acetate, vinylpyrrolidone or methyl vinyl ether.
The level of monomers (a) is advantageously between 3 and 80 mol %, preferably 10 to 60 mol %.
The level of monomers (b) is advantageously between 10 and 95 mol %, preferably 20 to 70 mol %.
The level of monomers (c) is advantageously between 0 and 50%, preferably 0 and 30%, very particularly from 5 to 25 mol %.
The molar ratio of cationic monomer to the anionic monomer (a)/(b) is advantageously between 80/20 and 5/95, preferably between 60/40 and 20/80.
The copolymers of the invention can be obtained according to known techniques for the preparation of copolymers, in particular by polymerization by the radical route of the starting ethylenically unsaturated monomers, which are known compounds or compounds which can be easily obtained by a person skilled in the art by employing conventional synthetic processes of organic chemistry.
Reference may in particular be made to the processes disclosed in U.S. Pat. No. 4,387,017 and EP 156,646.
The radical polymerization is preferably carried out in an environment which is devoid of oxygen, for example in the presence of an inert gas (helium, argon, and the like) or of nitrogen. The reaction is carried out in an inert solvent, preferably ethanol or methanol, and more preferably in water.
The polymerization is initiated by addition of a polymerization initiator. The initiators used are the free radical initiators commonly used in the art. Examples comprise organic peresters (t-butylperoxy pivalate, t-amylperoxy pivalate, t-butylperoxy α-ethylhexanoate, and the like); organic compounds of azo type, for example azobisamidinopropane hydrochloride, azobisisobutyronitrile, azobis(2,4-dimethylvaleronitrile), and the like); inorganic and organic peroxides, for example hydrogen peroxide, benzyl peroxide and butyl peroxide, and the like; redox initiating systems, for example those comprising oxidizing agents, such as persulfates (in particular ammonium or alkali metal persulfates, and the like); chlorates and bromates (including inorganic or organic chlorates and/or bromates); reducing agents, such as sulfites and bisulfites (including inorganic and/or organic sulfites or bisulfites); oxalic acid and ascorbic acid, as well as the mixtures of two or more of these compounds.
The preferred initiators are water-soluble initiators. Sodium persulfate and azobisamidinopropane hydrochloride are in particular preferred.
In an alternative form, the polymerization can be initiated by irradiation using ultraviolet light. The amount of initiators used is generally an amount sufficient can produce initiation of the polymerization. The initiators are preferably present in an amount ranging from 0.001 to approximately 10% by weight with respect to the total weight of the monomers and are preferably in an amount of less than 0.5% by weight with respect to the total weight of the monomers, a preferred amount being situated in the range from 0.005 to 0.5% by weight with respect to the total weight of the monomers. The initiator is added to the polymerization mixture either continuously or noncontinuously.
When it is wished to obtain copolymers of high molecular mass, it is desirable to add fresh initiator during the polymerization reaction. The gradual or noncontinuous addition also makes possible a more efficient polymerization and a shorter reaction time. The polymerization is carried out under reaction conditions which are effective in polymerizing the monomers (a), the monomers (b) and optionally the monomers (c) under an atmosphere devoid of oxygen. The reaction is preferably carried out at a temperature ranging from approximately 30° to approximately 100° and preferably between 60° and 90° C. The atmosphere which is devoid of oxygen is maintained throughout the duration of the reaction, for example by maintaining a nitrogen flow throughout the reaction.

The copolymers according to the invention can be used in particular in cleaning compositions for hard surfaces.
In the cleaning field, the copolymers of the invention are of use in conferring hydrophilization properties on surfaces to which they are applied, in particular in conferring persistent properties of resistance to stains or marks on surfaces.
In addition, they exhibit the property of preventing or of limiting the corrosion of glass, dishes and designs by washing media during repeated washing operations in an automatic dishwasher.
The term “persistent properties of resistance to marks or stains” is understood to mean that the treated surface retains these properties over time, including after subsequent contacts with water, whether rainwater, water from the supply system or rinsing water, which may or may not have rinsing products added.
Another subject-matter of the invention is the novel copolymers as defined above.
Said copolymer can be introduced into a cleaning or rinsing formulation intended for the treatment of hard surfaces at a content of between 0.0005% and 10%, preferably between 0.001 and 5%, by weight with respect to the total weight of the formulation, according to the concentration of active ingredients in the composition.

The mixture obtained is heated gently to 75° C. at a pH of approximately 2.6 under a gentle nitrogen flow. After 30 minutes, when the temperature reaches 75° C., an initiator solution based on sodium persulfate (0.1 g in 1.0 g of demineralized water) is added to the reactor in a single step. Cooling is necessary in order to keep the temperature at 75° C. and the mixture becomes viscous after approximately 45 minutes. Two additional portions of initiating solution based on persulfate are added after reacting for one and two hours respectively. The reaction mixture is subsequently heated to a temperature of 85° C. and maintained at this temperature for an additional two hours before being cooled to 25° C. The viscosity of the resulting solution of Polymer 1 is approximately 29,500 cps with a total content of solids of approximately 20.5%. The pH of the 10% solution is approximately 2.2. The residual acrylamide is less than 0.1% by weight.

Glass Corrosion Test
This simplified glass corrosion test reproduces certain washing conditions of dishwashers, in particular washing, rinsing and drying cycles.
Nature of the Glass
The glass used is composed of microscope slides with dimensions of 2.5×7.5 cm cleaned beforehand with ethanol, the composition of which slides, given below, is similar to that of table glasses:
    • Si: 21-43% by weight
    • Ca: 2.8-5.8% by weight
    • Mg: 1.6-3.4% by weight
    • Na: 6.8-14.2% by weight
    • Al: 0.3-0.7% by weight
      Procedure
200 ml of an aqueous washing solution comprising 6 g/l of product to be tested are introduced into a container. The container is introduced into and held in an oven at 65° C. for 1 hour.
A glass slide is completely immersed in this container in the inclined position. The container is then closed and then placed in an oven at 65° C. The slide is taken out of the container after 72 hours, rinsed twice on each face with deionized water using a wash bottle, touched lightly with the finger in order to remove the film which may have been formed and dried in the surrounding air for 2 hours.
At the end of the test, the slide is weighed after cooling to room temperature and the relative mass variation (as %×1000) is calculated. The test is repeated another time for confirmation of the results.
The corrosion visible to the eye is evaluated with respect to a reference slide which has not been subjected to the test.
The evaluation of corrosion is carried out visually by nine trained people with a scale ranging from 1 to 5 points, the glasses in the fresh state being taken as reference.
The points are distributed as follows:
    • 1 point corresponds to a perfect state.
    • 2 points correspond to damage which is scarcely visible (colorless or colored marks on design-free glasses; matting of the design of the glass).
    • 3 points correspond to very marked damage which is spontaneously visible (design-free glasses covered all over with colored or colorless marks, optionally with the presence of local defects; the glass designs are matt, with fading of the colors).
    • 4 points correspond to very significant damage (the design-free glasses also exhibit broad white stains; the glass designs have partially disappeared).
    • 5 points correspond to completely debased surfaces (the whole surface is damaged; the designs have disappeared).
Finally, the pH of the solutions is measured at room temperature before the immersion of the slide and at the end of the experiment.
This simplified test makes it possible to rapidly reproduce the various types of glass corrosion obtained by the repeated washing in a dishwasher, the sequence of the washing-rinsing-drying cycles, under concentration and temperature conditions similar to those used in dishwashers.

The biocide Rhodaquat RP50 is an aqueous solution of (C12-C14 alkyl)benzyldimethylammonium chloride with an active material content of 50% sold by Rbodia.
The Formulation of Example 26 is Tested on a White Ceramic Tile According to the Following Protocol:
1. 3 g of dilute aqueous biocidal solution are added to the surface of the ceramic tile (5 cm×5 cm) sterilized beforehand by cleaning with isopropyl alcohol. The tile is dried at 45° C. in an oven.
2. The surface of the tile is positioned vertically and is sprayed with one gram of water using a hand sprayer. This corresponds to a washing operation without mechanical action. Between 0 and 15 washing operations are thus carried out before drying at 45° C.
3. 0.25 ml of an aqueous medium comprising approximately 108 CFU/ml of Gram negative bacterium, Pseudomonas aeruginosa, is added and is spread over the pretreated hard surface.
4. The tile is left at room temperature for 3 hours, in order to allow the biocide to migrate from the surface of the polymer and to kill the surface bacteria.
5. The tile is dried at 37° C. for at least 30 minutes.
6. The surviving microorganisms are recovered by using a sterile cottonwool pad moistened beforehand with a neutralizing solution. The entire surface is carefully cleaned by wiping 4 times in all directions.
7. The pad is introduced into 9 ml of neutralizing medium; the volume is adjusted to 10 ml with water. The bacterial suspension is transferred onto Nutrient Agar in Petri dishes by successive dilutions by a factor 10.
8. The dishes are incubated at 37° C. for 48 hours and the surviving microorganisms are counted.
    • The neutralizing medium comprises 3% of Tween 80 polysorbate and 2% of soybean lecithin.
    • A control test is performed by carrying out Stages 1. to 7. on the surface of a white ceramic tile (5 cm×5 cm) which has been sterilized beforehand but which has not been treated with the biocidal system.
    • The log10 for reduction of the number of bacteria is calculated as follows:
      log10 for reduction=log10 N/n
    • N being the number of surviving bacteria (in CFU/ml) in the control test
    • n being the number of surviving bacteria (in CFU/ml) in the test employing the biocidal system.
      Results
The results of the above test appear in the following table.

The results show:
    • that an aqueous solution of biocidal agent alone does not withstand the 15 rinsing operations,
    • that the interaction between the biocide and the polymer introduces long-term protection of the surface against bacteria, without damaging the short-term bactericidal performances,
    • that the polymer in itself does not have a biocidal action.
