Patent Images
1. An isotropic liquid cleansing composition comprising:
- (a) about 1 to 35 wt. % of surfactant(s) selected from an anionic, nonionic, amphoteric or cationic surfactant or mixtures thereof;
(b) a thickening agent;
(c) about 0.1% to 10% of a cationic polymer;
(d) an effective concentration of a solid particulate optical modifier for exhibiting a specific set of optical properties on skin characterized by one or more skin evaluation methods selected from Tile evaluation method, Hand wash (consumer evaluation) method, Hand wash (lab evaluation) method, or a set of Tristimulus Color Values L, a*, and b*;
a reflectivity change, and an opacity change, that provides at least a 5% change in at least one of the specific optical properties when said cleansing composition is applied to skin and then rinsed off using the In-vitro Visual Assessment Protocol; and
(e) wherein the viscosity of the isotropic cleansing composition is in the range of about 1,000 to 300,000 cps @ 1/sec shear rate at 25 C via the cone and plate method.
