Isopropyl jojobate is the ester of isopropyl alcohol and the acids derived from jojoba oil.[1] Isopropyl jojobate is commonly used in cosmetic formulations.

Chemical structure

[edit]

Isopropyl jojobate is the isopropyl ester of the unfractionated saponification product of jojoba oil. It consists of a mixture of jojoba alcohols and the esters of isopropyl alcohol and jojoba acids. There are typically also unsaponified wax esters present in isopropyl jojobate.

Physical properties

[edit]

Isopropyl jojobate is an odorless, pale amber liquid at room temperature. The viscosity of isopropyl jojobate is much lower than that of jojoba oil.

Uses

[edit]

Isopropyl jojobate is often used in cosmetic formulations as a pigment wetting agent and emollient. It is often found in lipsticks, eye shadows, blushers, foundations, (especially stick foundations) and hair dyes.
