Cetyl Alcohol: Emollient and Thickening Agent for Topical Formulations
Cetyl alcohol (1-hexadecanol, C16 fatty alcohol) is a long-chain fatty alcohol used as an emollient, emulsion stabilizer, and thickening agent in pharmaceutical creams, ointments, and cosmetic products. It imparts a characteristic smooth, velvety texture and contributes to the structural integrity of semi-solid formulations.

Formulation Applications
Cetyl alcohol serves dual roles in topical formulations: as a co-emulsifier that stabilizes O/W emulsions by participating in gel-network formation at the oil-water interface, and as an emollient that reduces transepidermal water loss. It is frequently combined with stearyl alcohol as cetostearyl alcohol or paired with nonionic surfactants for stable emulsion systems. In hair care products, it provides conditioning and detangling benefits. Cetyl alcohol has a melting point of approximately 49°C and is processed by melting into the oil phase during emulsion preparation. It is generally non-irritating and well-tolerated by most skin types.
