CETEARETH-18

Description

Ceteareth-18 is a versatile emulsifier and surfactant widely used in skincare and cosmetic formulations. This synthetic ingredient is derived from the ethoxylation of cetearyl alcohol, a fatty alcohol blend of cetyl and stearyl alcohols. Ceteareth-18 functions primarily as an emulsifying agent, helping to stabilize oil-in-water emulsions and create smooth, creamy textures in various products.

With an HLB (Hydrophilic-Lipophilic Balance) value of approximately 15, Ceteareth-18 excels at forming stable emulsions and enhancing the solubility of other ingredients. It aids in the even distribution of active ingredients throughout formulations, ensuring consistent product performance. This compound also acts as a mild surfactant, contributing to cleansing properties in some applications.

Ceteareth-18 is particularly valuable in leave-on skincare products such as lotions, creams, and serums, where it helps to improve spreadability and absorption. Its emollient properties contribute to a soft, non-greasy skin feel. While generally well-tolerated, as with all ethoxylated ingredients, it may cause irritation in some individuals with sensitive skin. Formulators appreciate Ceteareth-18 for its stability across a wide pH range and compatibility with various cosmetic ingredients.
