ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The subject matter of the present invention is a hair treatment composition containing a terpolymer of vinyl pyrrolidone, vinyl caprolactam and a basic acrylamide monomer and an additional cation-active hair-care material.
2. Prior Art
Hair treatment compositions, which impart volume and hold to the hair, are known. The cosmetic polymers normally used for this purpose have good fixing properties in aqueous or alcoholic solutions, which shape and fix the hair more or less well after application and can also impart more volume to the hair. However frequently this effect does not last long and the desired volume imparting effect is already partially lost by combing the hair thoroughly. The hair style already collapses in a few hours especially with fine hair, i.e. the volume effect does not last over an entire day from morning to evening. Many of the fixing or volume imparting polymers have frequently undesirable side effects, which are made noticeable because the treated hair feels rough, has too high a load or insufficient elasticity or too much visible residue builds up on the hair.
Terpolymers of vinyl pyrrolidone, vinyl caprolactam and 3-(N-dimethylaminopropyl)methacrylamide are known from WO 96/19971. The use of these polymers in fixing compositions, especially in aerosol and pump sprays, is also known. These polymers are especially suitable for use in aqueous spray formulations with a reduced content of readily volatile organic ingredients (low VOC sprays). The polymers have good fixing properties, but impart a relatively rough feel to the hair and produce a comparatively high load on the hair.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a hair treatment composition that has the advantages of a typical styling composition, and especially is characterized by a long-lasting volumizing effect, while at the same time it guarantees good hair care properties, especially in regard to elasticity, reduced load and reduced residue on the hair.
It is also an object of the present invention to provide a hair treatment composition with ingredients, which are compatible with each other, i.e. the composition should be homogeneous, clear and unintended precipitation of ingredients should be avoided.
It has now been found that these objects are attained by a hair treatment composition comprising
(A) at least one terpolymer of vinyl pyrrolidone, vinyl caprolactam and a basic acrylamide monomer, and
(B) at least one hair-care material with at least one cationic group.
The terpolymer (A) is contained in the composition according to the invention preferably in an amount of from 0.01 to 20, especially preferably from 0.1 to 5, percent by weight, and the cationic hair-care material is contained in an amount of from 0.01 to 10 percent by weight, especially preferably from 0.05 to 5 percent by weight.
DETAILED DESCRIPTION OF THE INVENTION
Suitable terpolymers (A) include those in which the acrylamide monomer is selected from the group consisting of dialkylaminoalkylmethacrylamides having alkyl group containing one to four carbon atoms and dialkylaminoalkylacrylamides having alkyl group containing one to four carbon atoms. Dimethylaminopropylmethacrylamide is especially preferred. A method of making a polymer of this type is described in WO 96/19971. This polymer can be obtained commercially under the trademark AQUAFLEX® SF 40 (ISP).
The cationic material (B) is a substance, which has a substantive action on human hair because of its cationic or cationizable groups, especially primary, secondary, tertiary or quaternary amine groups. Suitable cation-active substances are selected from the group consisting of cationic surfactants, amphoteric betainic surfactants, cationic polymers, silicone compounds with cationic or cationizable groups, cationic derivatized proteins or protein hydrolyzates and betaine.
Suitable cation-active surfactants are surfactants which contain a quaternary ammonium groups. Cation-active surfactants include cationic or amphoteric betainic surfactants. Suitable cationic surfactants contain amino groups or quaternarized hydrophilic ammonium groups, which carry a positive charge in solution and can be represented by the general formula I:

(−)
represents an anion, especially halogen, acetate, phosphate, nitrate or alkylsulfate, preferably chloride. The aliphatic groups can also have cross-linkages or other groups such as amino groups.
For example, the following are suitable cationic surfactants: the chlorides or bromides of alkyidimethylbenzyl ammonium salts, alkyltrimethyl ammonium salts, especially cetyltrimethyl ammonium chloride or cetyltrimethyl ammonium bromide, tetradecyltrimethyl ammonium chloride or tetradecyltrimethyl ammonium bromide, alkyldimethylhydroxyethyl ammonium chloride or alkyldimethylhydroxyethyl bromide, dialkyldimethyl ammonium chloride or dialkyldimethyl ammonium bromide, alkylpyridinium salts, especially laurylpyridinium chloride or cetylpyridinium chloride, alkylamidoethyl trimethyl ammonium ether sulfate and compounds with cationic character, such as amine oxides, especially alkylmethylamine oxide or alkylaminoethyldimethylamino oxide. Cetyltrimethyl ammonium chloride is particularly preferred, for example in the form of a 26 percent aqueous solution marketed under the trademark DEHYQUART® A of Hinkel KGaA, Düsseldorf, Germany; and under the trademark GENAMIN® CTAC of Hoechst AG, Frankfurt, Germany and in the form of a 50 percent solution in isopropanol under the trademark ARQUAD® 16-50 of Akzo Chemicals GmbH, Düren, Germany.
Suitable amphoteric surfactants are derivatives of aliphatic quaternary ammonium, phosphonium and sulfonium compounds of formula (II):
