Abstract
An aqueous isotropic liquid cleansing and moisturizing composition is provided having a surfactant; a thickening agent, and organogel particles with a structure comprising a benefit agent and a gellation agent. In a preferred embodiment the inventive cleansing composition includes a free emollient having a weight average emollient particle size in the range about 1 to about 500 microns.
Claims27
An isotropic liquid cleansing composition comprising:
- (a) a surfactant selected from an anionic, nonionic, amphoteric and cationic surfactant and mixtures thereof;
- (b) a thickening agent;
- (c) about 0.1 to about 25% by weight of organogel particles of from about 0.05 to about 10 millimeters in diameter, the organogel particle comprising a benefit agent that is a liquid at about 75° C. and a gelation agent that is a solid at about 25° C., the proportions of the gelation agent to benefit agent being between about 0.05% to about 70% by weight gelation agent to benefit agent, the solidification or gelation temperature of the mixture being at or above about 25° C.;
- and
- (d) wherein the viscosity of the cleansing composition as measured without the organogel particles is in the range of about 1,000 to about 300,000 cps@1/sec shear rate at 25 C.

A method of depositing a benefit agent from an isotropic liquid cleansing composition, comprising the steps of:
- (a) providing said benefit agent in said cleansing composition including:
- 1. a surfactant selected from anionic, nonionic, amphoteric and cationic surfactants, and mixtures thereof;
- 2. a thickening agent,
- 3. about 0.1 to about 25% by weight of organogel particles of from about 0.05 to about 10 millimeters in diameter, the organogel particles comprising the benefit agent that is a liquid at about 75° C. and a gelation agent that is a solid at about 25° C., the proportions of the gelation agent to benefit agent being between about 0.05% to about 70% by weight gelation agent to benefit agent, the solidification or gelation temperature of the mixture being at or above about 25° C.;
- and
- (c) applying said cleansing composition to the skin or hair.
