LAURETH-21

Description

Laureth-21 is a versatile synthetic emulsifier and surfactant widely used in cosmetic and personal care formulations. This nonionic compound is derived from lauryl alcohol and ethylene oxide, resulting in a polyethylene glycol ether of lauryl alcohol with an average of 21 ethylene oxide units. Its molecular structure grants it excellent solubilizing properties, making it particularly effective in creating stable emulsions and facilitating the incorporation of oil-soluble ingredients into water-based products.

In skincare formulations, Laureth-21 serves multiple functions. It acts as an emollient, helping to soften and smooth the skin's surface. Its emulsifying capabilities allow for the seamless blending of oil and water phases in creams, lotions, and serums. Additionally, Laureth-21 enhances the spreadability of products, improving their texture and application experience.

This ingredient is also valued for its ability to reduce surface tension, which aids in the even distribution of active ingredients across the skin. While generally well-tolerated, Laureth-21 may cause mild irritation in individuals with sensitive skin. Its efficacy and multifunctionality make it a popular choice among formulators seeking to create stable, effective skincare products with desirable sensory attributes.
