Abstract

An emollient composition is derived from jojoba oil comprises:

at least 10% by weight fatty alcohols comprising:

R.sup.1 CH.sub.2 --OH

at least 10% by weight of alkyl esters comprising:

R.sup.1 --COO--R.sub.4

and

wax esters selected from the group consisting of:

R.sup.1 --COO--CH.sub.2 --R.sup.2

and

R.sub.2 --COO--CH.sub.2 --R.sub.1,

wherein R⁴ comprises an alkyl or other aliphatic group,

R¹ comprises CH₃ --(CH₂)₇ --CH═CH--CH₂ --(CH₂)_x --, and

R² comprises CH₃ --(CH₂)y wherein

x is 6, 8, 10 and 12, and y is 16, 18, 20 and 22.

These emollient compositions may be used as emollient carriers for various materials to be externally applied to the skin.
