Abstract
An ordered liquid crystalline phase cleansing composition is disclosed that contains particles with a structure comprising a benefit agent and a gellation agent and provides high foaming with in a preferred embodiment levels of free emollient equal to or in excess of the level of surfactant. A method of depositing a benefit agent to the skin or hair with the ordered liquid crystalline phase cleansing composition is also disclosed.
Claims24
An ordered liquid crystalline phase cleansing composition comprising:
- (a) about 3 to about 30% by weight of a surfactant system including at least one surfactant selected from an anionic, amphoteric, cationic and nonionic surfactant and mixtures thereof, wherein at least one anionic surfactant must be present;
- (b) about 0.1% to about 15% by wt. of an ordered liquid crystalline phase inducing structurant;
- (c) about 0.1 to about 25% by weight of organogel particles of from about 0.05 to about 10 millimeters in diameter, the 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
- wherein said ordered liquid crystalline phase composition has a viscosity of about 40,000 to about 300,000 cps at 25 C.
A method for depositing a benefit agent on to the skin or hair with an ordered liquid crystalline phase cleansing composition, said composition comprising:
- (a) about 3 to about 30% by weight of a surfactant system including at least one surfactant selected from an anionic, amphoteric, cationic and nonionic surfactant and mixtures thereof, wherein at least one anionic surfactant must be present;
- (b) about 0.1% to about 15% by wt. of an ordered liquid crystalline phase inducing structurant;
- (c) about 0.1 to about 25% by weight of particles of from about 0.05 to about 10 millimeters in diameter, the 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
- wherein said ordered liquid crystalline phase composition has a viscosity of about 40,000 to about 300,000 cps at 25 C.
