Cosmetic skin compositions containing a weak carboxylic acid and a random copolymer of ethylene oxide and propylene oxide. The copolymer reduces skin irritation that is sometimes caused by the weak acid active without reducing delivery of weak acids to skin tissues. A method of reducing skin irritation that may be caused by the topical application of a weak carboxylic acid is also described.

Cette invention concerne des compositions cosmétiques pour la peau renfermant un acide carboxylique faible ainsi qu'un copolymère d'oxyde d'éthylène et un oxyde de propylène statistiques. Le copolymère atténue l'irritation de la peau provoquée dans certains cas par la faible activité acide sans compromettre l'administration d'acides faibles aux tissus cutanés. L'invention concerne également une méthode permettant d'atténuer l'irritation de la peau provoquée par l'application topique d'un acide carboxylique faible.
