'''Hydrogenated jojoba oil''' is the end product of the complete [[hydrogenation]] of [[jojoba oil]].
=== Chemical structure ===
Hydrogenated jojoba oil is a straight-chain [[wax ester]] of 36 to 46 carbons in length, an ester bond in the approximate middle of the chain, no branching, no points of unsaturation, and terminal methyl groups at each end. As with jojoba oil, there is no [[triglyceride]] component of hydrogenated jojoba oil.
=== Physical properties ===
Hydrogenated jojoba oil is a hard, crystalline wax ester. The melting point is 68-70 °C and the iodine value is < 2.0, making it one of the very few commercially available, high-melting-point wax esters of botanical origin. Hydrogenated jojoba oil is relatively colourless and odourless. Hydrogenated jojoba oil contains no trans isomers.
=== Uses ===
Hydrogentated Jojoba Oil has particular functionality in cosmetics, due to its ability to strengthen the wax matricies of "stick" formulations such as lipstick, eyeliner, lip balm et.al. Hydrogenated jojoba oil is often used as a material for [[Exfoliation (cosmetology)|exfoliation]] particles due to its uniform color, hardness, and controllable crystalinity.
