Choleth-15

What is Choleth-15?

Choleth-15 is a non-ionic surfactant created by ethoxylating cholesterol, a natural sterol lipid from animal cell membranes, with 15 ethylene oxide units. This modification balances hydrophilic and lipophilic properties, making it effective in cosmetic emulsions. Commonly used in skincare products like moisturizing creams, lotions, body washes, and shampoos, it functions by reducing interfacial tension between immiscible oil and water phases. Choleth-15 forms a protective film around oil droplets, preventing coalescence and ensuring long-term stability. This results in products with consistent viscosity, easy spreadability, and uniform distribution of ingredients. Its gentle profile supports formulation of everyday personal care items without compromising texture or performance.
