Patent ID: 7300912

Claim:
A cleansing system that foams upon contact with water and that comprises a plurality of delivery particles, wherein each delivery particle contains one or more components selected from the group consisting of dry acids, dry bases, and film-forming cleansing agents, wherein when a delivery particle contains both dry acid(s) and dry base(s), the acid(s) and the base(s) are not in direct contact with each other, and wherein the plurality of delivery particles are core-shell delivery particles that each comprise: a core portion made of one or more optionally coated components selected from the group consisting of dry acids, dry bases, and hair and skin conditioners; and a shell portion made of one or more components selected from the group consisting of film-forming cleansing agents, and mixtures of film-forming cleansing agents and hair and skin conditioners, and wherein when the delivery particles are exposed to water, the particles will dissolve or break apart thereby releasing the components contained therein, the released acids(s) and the released bases(s) will then react to form a gas and the cleansing agents(s) will form a liquid film, and the gas and the liquid film will then interact to form or generate a foam.
