Combinations of polymer compounds and hair treatment compositions containing them are described, which have improved film-forming properties and improved hair-fixing properties, particularly increased elasticity of the polymer film or the treated hair. The polymer compound combinations include at least one terpolymer of vinyl pyrrolidone, vinyl caprolactam and basic acryl amide monomer and at least one anionic or anionizable polymer with anionic or anionizable groups.
An aqueous, alcoholic or aqueous-alcoholic hair treatment composition comprising a polymer combination in an aqueous, alcoholic or aqueous-alcoholic cosmetic base, wherein said polymer combination consists of at least one terpolymer of vinyl pyrrolidone, vinyl caprolactam and a basic acrylamide monomer and at least one anionic or anionizable polymer compound having anionic or anionizable groups;
An aqueous, alcoholic or aqueous-alcoholic hair treatment composition comprising a polymer combination in an aqueous, alcoholic or aqueous-alcoholic cosmetic base, wherein said polymer combination consists of at least one terpolymer of vinyl pyrrolidone, vinyl caprolactam and a basic acrylamide monomer and at least one anionic or anionizable polymer compound having anionic or anionizable groups;
An aqueous, alcoholic or aqueous-alcoholic hair treatment composition comprising a polymer combination in an aqueous, alcoholic or aqueous-alcoholic cosmetic base, wherein said polymer combination consists of at least one terpolymer of vinyl pyrrolidone, vinyl caprolactam and a basic acrylamide monomer and at least one anionic or anionizable polymer compound having anionic or anionizable groups;

1. Field of the Invention
The subject matter of the present invention is a polymer combination, i.e. a combination of polymeric ingredients, and a hair treatment composition with a content of this polymeric combination. More particularly, the subject matter of the present invention is a hair treatment composition with a combination of at least one terpolymer selected from the group consisting of vinyl pyrrolidone, vinyl caprolactam and a basic acrylamide monomer as well as at least one polymer compound having an anionic or anionizable group.
2. Prior Art
The following examples illustrate the subject matter of the invention in further detail. The polymer compound amounts given in the examples are related to the amount of solid materials contained in the composition.
Comparative Tests
Seventeen polymer solutions were tested. All test solutions contained 3 percent by weight solids content in polymers, 4.5% by weight ethanol and 92.5% by weight water. Polymers containing acid groups were neutralized up to 100% with aminomethylpropanol. The samples E1 to E7 contained on respective single polymers in an amount of 3% by weight. The samples K1 to K10 contained combinations of two of these polymers in an amount of 1.5% by weight of each polymer. The samples K4 to K10 were not of the invention and the samples K1 to K3 were compositions according to the present invention. The following polymers and polymer combinations were tested:
