Abstract

Abstract A cosmetic composition comprises an aqueous solution of an anionic surface active agent selected from the group consisting of (a) a surface active agent of the formula RX-(AO)m--(A'O)n--A''-X'-CH-COOH (I) ¦ R' wherein R is selected from the group consisting of alkyl and alkenyl, each having 8 to 22 carbon atoms and alkylphenyl having 12 to 22 carbon atoms; X and X' are each selected from the group consisting of oxygen, sulfur and sulfoxide; A is selected from the group consisting of ethylene, propylene and butylene; A' is selected from the group consisting of -C2H3(CH2OH)- and -CH2CHOH-CH2-; A'' is selected from the group consisting of -CH2CHOH-CH2-, -CH2CH2CH2- and -CH2CH(CH3)- with the proviso that at least one of A' and A'' is hydroxyalkylene as set forth in the respective definitions of A' and A'' above; M AND N REPRESENT NUMBERS HAVING A STATISTICAL AVERAGE VALUE BETWEEN 0 AND 10 INCLUSIVE WITH THE PROVISO THAT N IS OTHER THAN 0 WHEN A'' is other than hydroxyalkylene and when m and n are both zero, X' is sulfoxide; R' is selected from the group consisting of hydrogen and a lower alkyl having from 1-12 carbon atoms; B. THE MAGNESIUM SALT OF (A); AND C. THE ALKANOLAMINE SALT OF (A), SAID SURFACE ACTIVE AGENT BEING PRESENT IN AMOUNTS RANGING FROM 0.1-20% BY WEIGHT OF SAID COMPOSITION.
