STEARETH-40

Description

STEARETH-40 is a versatile synthetic emulsifier and surfactant widely used in cosmetic and personal care formulations. This non-ionic compound is derived from ethoxylated stearyl alcohol, with an average of 40 ethylene oxide units per molecule. Its chemical structure allows it to effectively bridge the gap between oil and water phases, making it invaluable in creating stable emulsions and enhancing product texture.

In skincare formulations, STEARETH-40 functions as an emollient and thickening agent, contributing to improved product consistency and skin feel. Its high molecular weight and large number of ethylene oxide units make it particularly effective in stabilizing oil-in-water emulsions, such as lotions and creams. This ingredient also aids in the dispersion of pigments and other active ingredients, ensuring uniform distribution throughout the product.

STEARETH-40 is known for its mild nature and good compatibility with various skin types. It helps to reduce surface tension, allowing for better spread and absorption of formulations. Additionally, it can act as a solubilizer, assisting in the incorporation of fragrances and essential oils into water-based products. While generally considered safe for cosmetic use, as with any ingredient, patch testing is recommended for individuals with sensitive skin.
