What is Isocetyl Alcohol?

Isocetyl Alcohol is a branched-chain primary alcohol with 16 carbon atoms, often derived from natural fatty acids like those in coconut oil or synthesized for purity. It belongs to the category of emollient alcohols used widely in skincare products such as lotions, creams, and makeup. In formulations, it functions by aligning with skin lipids to lubricate the surface, promoting smoothness and ease of application without greasiness. It also controls viscosity by influencing the flow and thickness of emulsions, ensuring even distribution and stability. As a skin conditioner, it supports the skin's barrier by reducing transepidermal water loss when combined with other ingredients, contributing to a supple texture. Its branched structure makes it less occlusive than linear alcohols, ideal for lighter textures.
