Dicaprylyl Carbonate description

Dicaprylyl carbonate is a skin-conditioning agent, emollient, and solvent that helps enhance the absorption of other ingredients in a cosmetic formula. It may be derived from synthetic or animal sources; Paula’s Choice Skincare uses the synthetic form. Dicaprylyl carbonate is produced by BASF, where it’s listed under the trade name Cetiol® CC. BASF says that it is a fast-spreading, dry emollient whose ability to dissolve crystalline UV filters and to disperse pigments makes it particularly suitable for sun care products. It has been deemed safe as used in cosmetics products, where it may be used in concentrations up to 34.5% in leave-on products.
