Abstract
A rinse-off liquid personal cleansing composition comprising surfactant and water wherein the composition comprises less than 8% of a first surfactant selected from a crystallizing anionic surfactant and greater than 3% of a second surfactant selected from non-crystalizing anionic surfactants, amphoteric surfactants, nonionic surfactants, zwitterionic surfactants, and mixtures thereof, and wherein the composition has a Mean Rinse Feel Value of 3.5 or less as measured by the Rinse Feel Panel Test. The personal cleansing compositions of the invention provide excellent rinse feels and skin mildness.
Claims25

- wherein R1 is H or C1-C4 alkyl, R4 is C1-C4 alkyl, R2 is H or C1-C4 alkyl or C2-C4 alkenyl, and R3 is H or C1-C4 alkyl or C2-C4 alkenyl, n is an integer from 0 to 3 and m is an integer of from 1 to 1000 and having a number average molecular weight of from about 600 to about 1000, and
- (iii) hydrophobically modified silicones having the following formula:
- wherein R is C1-C4 alkyl or phenyl, R′ is C1-C20 alkyl or phenyl, z is 5 to 21, and x has a number average value in the range of from about 20 to 400, y has a number average value in the range of from about 0 to about 10 and x+y lies in the range of 30 to 400;
- (d) tip to 10% by weight of petrolatum and mineral oil;
- and
- (e) water,
- wherein the composition has a Mean Rinse Feel Value of 3.5 or less as measured by a Rinse Feel Panel Test.
