2079098 9116037 PCTABS00007 Skin-cleansing compositions with a mildness additive that is a non-water soluble acrylate polymer that is soluble in poorly hydrogen bonding solvents or solvent blends having a solubility parameter of between about 8.4 and 10.4 (cal/cc)1/2. The polymer comprises monomers of formula (I), wherein R1 is H or an alkyl radical containing 1 to 18 carbon atoms in cyclic, straight- or branched-chain configuration and is saturated or unsaturated; R2 is hydrogen, lower alkyl or -CH2CO2R1; and R3 is hydrogen, methyl or --CO2R1; provided, that when R2 is not hydrogen, R3 is hydrogen, and when R3 is not hydrogen, R2 is hydrogen. The incorporation of the indicated polymers reduces the drying and irritating effect of conventional cleansing compositions on the skin.
