Laureth-4

Description

Laureth-4 is a versatile synthetic emulsifier and surfactant widely used in cosmetic and personal care formulations. Derived from lauryl alcohol and ethylene oxide, this non-ionic compound acts as a solubilizer, helping to blend oil and water-based ingredients in skincare products. Its emulsifying properties contribute to the stability and texture of creams, lotions, and cleansers.

In skincare formulations, Laureth-4 functions as a mild cleansing agent, helping to remove dirt and oil from the skin's surface without excessive drying. It also aids in the dispersion of fragrances and essential oils within aqueous solutions. The ingredient's low molecular weight allows it to penetrate the skin's upper layers, potentially enhancing the delivery of other active ingredients.

While generally considered safe for use in cosmetics, Laureth-4 may cause irritation in individuals with sensitive skin. It's important to note that this ingredient can be contaminated with 1,4-dioxane, a potential carcinogen, during the manufacturing process. However, proper purification techniques can minimize this risk. Formulators should consider the concentration of Laureth-4 in products, as higher levels may lead to increased skin permeability and potential irritation.
