PEG-3 STEARATE

Description

PEG-3 Stearate is a versatile emulsifying agent and surfactant commonly used in skincare and cosmetic formulations. This synthetic ingredient is derived from the esterification of stearic acid with polyethylene glycol (PEG). Its molecular structure consists of a hydrophilic PEG component and a lipophilic stearate chain, allowing it to effectively bridge oil and water phases in product formulations.

In skincare applications, PEG-3 Stearate functions primarily as an emulsifier, helping to create stable emulsions by reducing surface tension between oil and water components. This property is particularly valuable in lotions, creams, and other moisturizing products. Additionally, it acts as a mild surfactant, aiding in the cleansing process and enhancing the spreadability of formulations.

PEG-3 Stearate is generally well-tolerated by most skin types and is considered safe for use in cosmetic products. It helps improve the texture and feel of skincare formulations, contributing to a smooth and non-greasy finish. The ingredient also assists in the even distribution of active ingredients throughout a product, potentially enhancing their efficacy. While PEG-3 Stearate is not an active ingredient itself, its role in formulation stability and texture improvement makes it a valuable component in many skincare products.
