PEG-20 STEARATE

Description

PEG-20 Stearate is a versatile emulsifying agent widely used in cosmetic and skincare formulations. This synthetic compound is derived from the esterification of stearic acid with polyethylene glycol (PEG). Its molecular structure consists of a hydrophilic PEG chain and a lipophilic stearate component, allowing it to effectively bridge oil and water phases in emulsions.

In skincare products, PEG-20 Stearate functions primarily as an emulsifier and surfactant, helping to create stable, homogeneous mixtures of oil and water-based ingredients. It contributes to the smooth texture and improved spreadability of creams, lotions, and other topical formulations. The ingredient also acts as a mild cleansing agent and can enhance the solubility of other components in the formula.

PEG-20 Stearate is generally considered safe for use in cosmetics, with a low risk of skin irritation. Its molecular weight allows for minimal skin penetration, reducing the potential for systemic absorption. The ingredient is often used in concentrations ranging from 0.1% to 5%, depending on the specific formulation requirements. While effective, formulators should consider potential ethylene oxide contamination and ensure proper purification of the raw material.
