Abstract
Abstract A facial cleanser especially useful for the removal of eye make-up is disclosed. A combination of mineral oil, certain phosphate esters and high molecular weight carboxy vinyl polymers, in the absence of water, forms a minimally irritating clear gel having a higher rinsability than mineral oil gelled by prior art methods.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
173 words
A composition of matter for use as a facial cleanser, consisting essentially of an anhydrous mixture of: (a) about 97 to about 49.5 parts by weight of mineral oil; (b) about 3 to about 50 parts by weight of at least one phosphate ester selected from the group consisting of compounds having the structure ##STR3## and mixtures thereof wherein M + is a univalent metal cation; R is a straight branched chain hydrocarbon radical containing 9 to 21 carbon atoms and 0 to 3 double bonds; Z is a member of the group consisting of ##STR4## and x is any number (on an average) from 1 to 10 sufficient to maintain the solubility requirement, depending on the value of R; (c) about 0.1 to about 5 parts by weight of a high molecular weight carboxy vinyl polymer comprised of acrylic acid which is cross-linked with a polymer of a co-polymerized polyalkenyl polyether, said mixture being a clear gel and said phosphate compound being soluble in said oil to at least 7% by weight.
