PEG-3 DIOLEATE

Description

PEG-3 Dioleate is a versatile emollient and emulsifier widely used in skincare and cosmetic formulations. This synthetic ingredient is derived from polyethylene glycol (PEG) and oleic acid, combining the hydrophilic properties of PEG with the lipophilic characteristics of fatty acids. Its molecular structure allows it to effectively bridge the gap between oil and water-based components in product formulations.

In skincare applications, PEG-3 Dioleate functions primarily as an emulsifier, helping to create stable emulsions by reducing surface tension between immiscible liquids. This property enables the uniform dispersion of active ingredients throughout the product, ensuring consistent efficacy. Additionally, it acts as a mild surfactant, aiding in the cleansing process without excessive drying of the skin.

The ingredient also exhibits emollient properties, contributing to improved skin texture and softness. It helps to form a protective barrier on the skin's surface, reducing transepidermal water loss and promoting hydration. PEG-3 Dioleate is generally well-tolerated by most skin types and is often used in leave-on and rinse-off products, including moisturizers, cleansers, and serums. Its low comedogenicity makes it suitable for formulations intended for acne-prone skin.
