Jojoba esters are the hydrogenation or interesterification product of Jojoba oil. Jojoba Esters are commonly used in cosmetic formulations as an emollient, due to its remarkable similarity to the natural oils produced by the human skin, and its high oxidative stability. Fully hydrogenated jojoba esters are most often small beads used to exfoliate the skin.
Physically, jojoba esters are an odourless, colourless liquid, white cream, or hard white wax, with melting points ranging from 15°C to 70°C. Their texture and crystallinity may be modified by rapid cooling, thus altering their cosmetic properties. Jojoba esters are very resistant to oxidation, more so than castor oil, coconut oil, macadamia oil, even many fractions of mineral oil.
Jojoba esters are mainly used as emollients in cosmetics such as lipsticks, shampoos and moisturizing lotions.
