About

A long-chain saturated fatty alcohol that functions as a skin conditioning emollient with excellent safety.

Pentadecyl alcohol (C15H31OH) is a saturated fatty alcohol with 15 carbons in its chain. Like other fatty alcohols in this class, it is valued for its emollient properties and skin-inert characteristics. It is not restricted under EU cosmetics regulation and has been evaluated by cosmetic safety bodies as safe for use in leave-on and rinse-off products. The odd-carbon chain length distinguishes it from more common even-carbon fatty alcohols.
