Abstract
Abstract A cosmetic cleansing composition capable of removing eye make-up comprises in an aqueous solution a cleansing agent comprising a mixture of surface active agents in the indicated amounts: (i) from 0.1 to 2 percent by weight, based on the total weight of said composition, as active material, of a glucoside alkylether having the formula ##STR1## wherein R represents alkyl having 8-12 carbon atoms, n is equal to 0, 1, 2, 3, 4 or 5; (ii) from 0.1 to 2 percent by weight, based on the total weight of said composition, as active material, of an amphoteric material of the formula ##STR2## wherein n is 0 or 1, y is 1 or 2, R represents a fatty chain having from 7 to 17 carbon atoms and R' represents --CH 2 --CH 2 OH or --(CH 2 ) 2 --O--(CH 2 ) 2 --COONa, optionally in admixture with an oxyethylenated alkyl sulfate of the formula C 13 H 27 --(OCH 2 CH 2 ) m --OSO 3 Na wherein m is 1-4 (III); and (iii) from 0.3 to 5 percent by weight, based on the total weight of said composition, as active material, of a compound selected from the group consisting of (a) the monolaurate or the mono-oleate of sorbitan polyoxyethylenated with 20 moles of ethylene oxide, (b) the monolaurate or the mono-oleate of glycerol polyoxyethylenated with 20 moles of ethylene oxide, and (c) a non-ionic compound having the formula ##STR3## wherein R represents a fatty chain having 8-10 carbon atoms, R' represents a fatty chain having 10-16 carbon atoms, and n ranges from 10 to 12, the ratio n/R+R' being between 0.4 and 0.6.
