Abstract:
A cosmetic foaming composition, comprising 0.005-20 weight percent of a foaming agent and a solvent, the foaming agent comprising a mixture of first and second nonionic surfactants and having a total HLB as measured by the Griffin method of at least 12, the first nonionic surfactant being selected from the group consisting ofa) a polyoxyethylene alkyl ether surfactant having the following general formula (I):CH.sub.3 --(CH.sub.2).sub.a --(OCH.sub.2 CH.sub.2).sub.n --OH (I)wherein a has an average value of from 9 to 21 and n has an average value of from 2 to 200;b) a polyoxyethylene alkenyl ether surfactant having the following general formula (II):CH.sub.3 --(CH.sub.2).sub.b --CH.dbd.CH--(CH.sub.2).sub.c --(OCH.sub.2 CH.sub.2).sub.n --OH (II)wherein b has an average value of from 1 to 10, c has an average value of from 1 to 10, and n has an average value of from 2 to 200;c) a polyoxypropylene polyoxyethylene ether surfactant having the following general formula (III):R.sub.1 --(OCH(CH.sub.3)CH.sub.2).sub.x --(OCH.sub.2 CH.sub.2).sub.y --OH (III)wherein R.sub.1 is selected from the group consisting of alkyl alkenyl groups, iso-alkyl alkenyl groups and dimethylpolysiloxane groups, x has an average value of from 2 to 100, and y has an average value of from 2 to 100; andd) mixtures thereof; and the second nonionic surfactant being selected from the group consisting of:e) a polyoxyethylene long chain alkyl fatty acid or benzene ether surfactant having the following general formula (IV):R.sub.2 --(OCH.sub.2 CH.sub.2).sub.n --OH (IV)wherein R.sub.2 is selected from the group consisting of castor oil triglyceride castorate, cholesterol, coconut oil triglyceride cocoate, alkyl phenol, glyceryl laurate, glyceryl oleate, glyceryl cocoate, glyceryl isostearate, glyceryl stearate, hydrogenated castor oil triglyceride hydrogenated castorate, hydrogenated lanolin, nonyl phenyl and dimethylpolysiloxane groups, and n has an average value of from 2 to 200;f) a polyoxyethylene ether surfactant having the following general formula (V):R.sub.3 --C(O)--(OCH.sub.2 CH.sub.2).sub.n --O--C(O)--R.sub.4 (V)wherein R.sub.3 and R.sub.4 are respectively selected from the group consisting of alkyl groups, iso-alkyl groups and alkenyl groups, and n has an average value of from 2 to 200;g) a polyoxypropylene ether surfactant having the following general formula (VI):R.sub.5 ---(OCH(CH.sub.3)CH.sub.2).sub.n --OH (VI)wherein R.sub.5 is selected from the group consisting of alkyl groups, iso-alkyl groups and alkenyl groups, and n has an average value of from 2 to 200; andh) mixtures thereof.
