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, stabailizing agents, binding agents, thickening agents, surfactants, and antimicrobials.

1-66. (canceled)
A personal care composition, comprising:
- at least one compound of Formula (I):
- wherein
- R1 is methyl or ethyl;

- R2 is a C30-45 alkenyl having at least one trans double carbon-carbon bond, or R2 is a C30-45 alkyl;
- provided that the compound of Formula (I) is not
- and
- optionally, at least one neutral lipid having a formula that is not Formula (I),
- wherein the ratio of compounds of Formula (I) to the neutral lipids having a formula that is not Formula (I) in the personal care composition is greater than 2:3.
A personal care composition, comprising:
- at least one compound of Formula (I):
- wherein
- R1 is methyl or ethyl;
