Abstract:
A method for the treatment of acne on the skin of a human subject comprising applying to said skin a skin care emulsion composition comprising:(a) from about 0.1% to about 12% of an acne regulating agent selected from the group consisting of antiinfectives, nicotinic acid, niacinamide, cucumber extract, panthenol, pantothenic acid, pyridoxine, riboflavin, hesperitin, phloretin, retinoids, antiinflammatories, keratolytic agents, antiandrogens, and mixtures thereof;(b) an anhydrous silicone mixture comprising(i) from about 0.1% to about 10% of an ethylene oxide/propylene oxide silicone copolymer of the formula ##STR5## wherein R.sup.a is an alkyl group of one to six carbon atoms; R.sup.b is the radical --C.sub.m H.sub.2m --; R.sup.c is a terminating radical which is hydrogen, an alkyl group of one to six carbon atoms, or phenyl; ""mm"" has a value of two to eight; ""p"" and ""s"" have values such that the oxyalkylene segment --(C.sub.2 H.sub.4 O).sub.p --(C.sub.3 H.sub.6 O).sub.s -- has a molecular weight in the range of 400 to 5,000; ""x"" has a value of 80 to 120; and ""y"" has a value of 2 to 10;(ii) from about 0.01% to about 10% of an ethylene oxide silicone copolymer of the formula ##STR6## wherein R.sup.a is an alkyl group of one to six carbon atoms; R.sup.b is the radical --C.sub.m H.sub.2m --; R.sup.c is a terminating radical is hydrogen, an alkyl group of one to six carbon atoms, or phenyl; ""m"" has a value of two to eight; ""p"" has a value of 8 to 16; ""x"" has a value of 6 to 12; and ""y"" has a value of 1 to 8;(iii) from about 0.1% to about 10% of a silicone gum; and(iv) from about 0. 1% to about 15% of a silicone fluid; and(c) water.
