Description
A liquid wax extracted from the seeds of evergreen shrubs, Simmondsia californica and Simmondsia chinensis, that are native to Arizona, California and northern Mexico. Jojoba oil is composed of C20 and C22 straight chain hydrocarbon acids and alcohols. Jojoba oil is stable, resistant to biological growth and can be stored for years without becoming rancid. The oil is substituted for sperm whale oil and is used in lubricants, lotions, shampoos, and leather dressing. The hydrogenated oil, called jojoba wax, is substituted for Beeswax and Carnauba wax in candles and cosmetics.
