PEG-3 Distearate

PEG / Ethoxylated

What is PEG-3 Distearate?

PEG-3 Distearate is a non-ionic synthetic compound formed by esterifying distearic acid with polyethylene glycol containing three oxyethylene units. This ethoxylated ingredient serves primarily in cleansing and moisturizing cosmetics, including shampoos, conditioners, lotions, creams, and body washes. It functions by reducing interfacial tension between immiscible oil and water phases, forming a protective film that stabilizes emulsions and prevents ingredient separation during storage or use. Its surfactant properties also promote wetting and dispersion, aiding in the even spread of products on skin or hair. Commonly derived from stearic acid sourced from vegetable oils or animal fats, it appears as a waxy solid and integrates seamlessly into formulations for enhanced consistency and mild performance across rinse-off and leave-on applications.
