10-Hydroxydecanoic Acid
What is 10-Hydroxydecanoic Acid?
10-Hydroxydecanoic acid is a saturated, straight-chain fatty acid featuring a hydroxyl group at the terminal carbon position, making it an omega-hydroxy acid. It occurs naturally in royal jelly as part of the lipid fraction and is also produced synthetically or obtained through hydrolysis of castor oil derivatives. Primarily categorized as an emollient in cosmetics, it appears in moisturizers, creams, and lotions at low concentrations. This ingredient functions by mimicking the skin's natural lipids, creating an occlusive layer that reduces transepidermal water loss while softening the outer skin layer. Its mild nature supports skin barrier integrity, contributing to a supple feel without penetration deep into the epidermis, distinguishing it from shorter-chain alpha hydroxy acids.
