Cosmetic compositions containing hydrophobically modified nonionic polymer and unsaturated quaternary ammonium surfactant

A cosmetic composition useful in application to the hair or skin, comprising:

• (a) from about 80% to about 100% by weight of the cosmetic composition of a vehicle system which comprises:
• (A) from about 0.1% to about 10.0% by weight of the cosmetic composition of a nonionic water-soluble polymer which comprises a water-soluble polymer backbone having grafted thereto hydrophobic groups selected from the group consisting of C.sub.8 -C.sub.22 alkyl, aryl alkyl, alkyl aryl groups and mixtures thereof, wherein the ratio of the hydrophilic backbone to the hydrophobic groups of the polymer is from about 10:1 to about 1000:1;
• (B) from about 0.02% to about 10.0% by weight of the cosmetic composition of unsaturated quaternary ammonium surfactant component of the formula:
• ##STR18## wherein X is a salt-forming anion, a is the ionic charge of X, the quaternary ammonium radicals R.sub.1, R.sub.2, R.sub.3, and R.sub.4 independently are C.sub.1 -C.sub.22 alkyl, C.sub.14 -C.sub.22 alkyl amido C.sub.2 -C.sub.6 alkylene, or benzyl, and from two to three of said quaternary ammonium radicals are C.sub.14 -C.sub.22 alkyl or C.sub.14 -C.sub.22 alkyl amido C.sub.2 -C.sub.6 alkylene or mixtures thereof, no more than two of said radicals being C.sub.14 -C.sub.22 alkyl amido C.sub.2 -C.sub.6 alkylene or a combination of C.sub.14 -C.sub.22 alkyl and C.sub.14 -C.sub.22 alkyl amido C.sub.2 -C.sub.6 alkylene, from one to two of said quaternary ammonium radicals are C.sub.1 -C.sub.6 alkyls, and no more than one of said radicals is benzyl;
• or ##STR19## wherein X is a salt-forming anion, a is the ionic charge of X, radicals R.sub.1, R.sub.2, and R.sub.3 independently are C.sub.1 -C.sub.22 alkyl or benzyl, and two or three of said radicals are C.sub.14 -C.sub.22 alkyl, or C.sub.14 -C.sub.22 alkyl amido C.sub.2 -C.sub.6 alkylene or a mixture thereof, zero or one of said radicals are C.sub.1 C.sub.6 alkyl, zero or one of said radicals is benzyl, or a mixture of a Formula I and II surfactants;
• wherein said quaternary ammonium surfactant component has a sufficient level of unsaturation in the C.sub.14 -C.sub.22 alkyl or C.sub.14 -C.sub.22 alkyl amido C.sub.2 -C.sub.6 alkylene radicals, or mixture thereof, such that average iodine value of said component is at least 15;
• and
• (C) from about 65% to about 99% by weight of the cosmetic composition of a compatible solvent for the nonionic water-soluble polymer;
• and
• (b) from 0% to about 20% by weight of the cosmetic composition of an additional cosmetic component;
• wherein said cosmetic composition comprises no more than about 1.0% by weight of water soluble surfactants.
