Jojoba oil

Liquid wax obtained by cold pressing the ripe seeds of Simmondsia chinenesis, the jojoba shrub.

The so-called "jojoba oil" is an almost odorless, oily, clear to yellow liquid at room temperature, which becomes viscous or solid at low temperatures. It is soluble in acetone, miscible with ether, fatty oils and kerosenes. In contrast to most vegetable oils, jojoba oil is not a fat but consists of wax esters (1 mole of a long-chain alcohol is esterified with 1 mole of a long-chain fatty acid). This composition of wax esters leads to the special characteristics of jojoba wax, in particular its high resistance to oxidation (rancidity). Jojoba oil is mainly used for cosmetic and skin care purposes.

In the cosmetics industry, see Hydrogenated jojoba oil (INCI), see also Hydrogenated jojoba wax (INCI).

Jojoba oil contains provitamin A and vitamin E and has a pleasantly caring character due to its favourable fatty acid composition (long-chain wax esters). Thus "Jojoba oil" does not leave an oily film on the skin when applied. It has a "non-occlusive effect (Patzelt A et al. 2012)" and because of these properties it is often used as massage oil.

Jojoba oil has an anti-inflammatory effect and can be used for a number of skin diseases (skin infections, skin aging, wound healing). A demonstrable effect of pure jojoba oil can be demonstrated in a mild Ache vulgaris (Meier L et al. 2012). It is also used in cosmetic formulations. Jojoba oil has a natural sun protection factor of about 3 and is therefore also used as base oil for sun protection products (Pazyar N et al. 2013; Touitou E et al. 2008).
