Abstract
Disclosed are facial cleansing compositions in the form of an oil-in-water emulsion which contain specific surfactants with an HLB above about 10 in combination with specific polyalphaolefins and specific carboxylic copolymers which provide improved cleansing efficacy as well as improved rinsability and improved skin feel (such as a nongreasy feeling).
Claims10
A cleansing composition for removing make-up in the form of an oil-in-water emulsion comprising:
- a. from about 0.5% to about 10% of a surfactant with an HLB greater than about 10 selected from the group consisting of anionic, nonionic, zwitterionic, amphoteric and ampholytic surfactants and mixtures thereof;
- b. from about 2% to 30% of polyalphaolefin of the formula:
- R.sub.1 --C.dbd.C--R.sub.2
- wherein R.sub.1 and R.sub.2 are independently from about C.sub.20 to about C.sub.30 alkyl, wherein said polyalphaolefin has a viscosity of from about 2 to about 4 centistokes at 100.degree. C.;
- and
- c. from about 0.025% to about 0.75% of a carboxylic copolymer comprising polymers of a monomeric mixture containing 95.9 to 98.8 weight percent of an olefinically unsaturated carboxylic monomer selected from the group consisting of acrylic, methacrylic and ethacrylic acids, about 1 to about 3.5 weight percent of an acrylate ester of the formula:
- ##STR7## wherein R is an alkyl radical containing 10 to 30 carbon atoms and R.sub.1 is hydrogen, methyl or ethyl, and 0.1 to 0.6 weight percent of a polymerizable cross-linking polyalkenyl polyether of a polyhydric alcohol containing more than one alkenyl ether group per molecule wherein the parent polyhydric alcohol contains at least 3 carbon atoms and at least 3 hydroxyl groups.
