jojoba ester
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.
==Chemical structure==
Jojoba esters are proper waxes; there is no triglyceride component of jojoba esters.
Chemically, jojoba esters are a complex mixture of long chain (C36-C46) fatty acids and fatty alcohols joined by an ester bond. Jojoba esters are produced by the interesterification of jojoba oil, hydrogenated jojoba oil, or a mixture of the two. Pure jojoba oil and pure hydrogenated jojoba oil are also correctly described as jojoba esters. The CTFA does not regard ''partially''-hydrogenated jojoba oil as jojoba esters. For this reason, jojoba esters must not contain any trans-unsaturation. Jojoba esters' chemical structure is very similar to that of human sebum and of whale oil.
