Available as crude wax (jojoba oil), hydrogenated jojoba wax, jojoba butter, and wax beads. Jojoba is an ingredient in cosmetics and hair treatments.
Jojoba oil is obtained from Simmondsia chinensis and S. californica seeds by expression or solvent extraction.
The highly stable jojoba oil (also referred to as liquid wax) contains longchain polycarbon esters of fatty acids and alcohols (eicosenoic, docosenoic, oleic and palmitoleic acids, eicosenol, docosenol); simmondsin; small quantities of campesterol, stigmasterol, and sitosterol; vitamin E; B vitamins; silicon; chromium; copper; zinc; and iodine.
Jojoba oil is considered to have emollient properties that soothe chapped skin, psoriasis, and sunburn; relieve dry scalp; remove embedded sebum to help such scalp disorders as dandruff and hair loss; and reduce the acidity of the scalp. An atherogenic diet containing 2% jojoba oil lowered cholesterol levels in rabbits. Antioxidant activity is probably related to the alpha-tocopherol content in jojoba .
Interest in jojoba has centered around its application as a dietary supplement for animal and poultry feed . Supplementation of the diet of broiler breeder hens with jojoba was found to promote smaller-sized eggs at a reduced rate of production. It was suggested that jojoba interfered with follicle growth, yolk deposition, progesterone production, and follicular maturation in the chickens .
Jojoba has been claimed to be effective in promoting hair growth and relieving skin problems. Its primary applications are to treat chapped and dry skin, dandruff, dry scalp, and psoriasis. Jojoba wax beads are used as an exfoliating agent in facial scrubs, skin conditioners, and soaps. Jojoba is also used as a replacement for petrolatum in creams, ointments, lotions, and lipsticks. Other claims include treatment of acne vulgaris, athlete's foot, cuts, eczema, hair loss, mouth sores, pimples, seborrhea, skin abrasions, warts, and wrinkles. Although little clinical evidence is available to support these claims, most applications appear to be based on theory and a long history of anecdotal use.
