Abstract

The use of long-chain alkenones to impart desired characteristics in personal care compositions for topical applications is described. The preparation of mixtures long-chain alkenones and synthetic derivatives thereof is presented. Examples of compositions include abrasive soaps, with alkenones serving as natural exfoliating agents. Alkenones and their derivatives can serve as emollients, occlusive agents, encapsulating agents, stabilizing agents, binding agents, thickening agents, surfactants, and antimicrobials.
