Polyethylene Glycol

Description

Polyethylene Glycol (PEG) is a versatile synthetic compound widely used in skincare and cosmetic formulations. This water-soluble polymer is derived from ethylene oxide and comes in various molecular weights, each offering distinct properties and functions. PEG acts as an effective humectant, drawing moisture to the skin and helping maintain hydration. Its emollient properties contribute to a smooth, soft skin feel upon application.

In skincare products, PEG serves multiple purposes. It functions as a thickening agent, enhancing product texture and stability. PEG also acts as a penetration enhancer, facilitating the absorption of other active ingredients into the skin. Its solubilizing properties enable the combination of water and oil-based ingredients, crucial for creating stable emulsions.

While generally considered safe for topical use, some individuals may experience sensitivity to PEG. Higher molecular weight PEGs are less likely to penetrate the skin, reducing the risk of irritation. Formulators often choose specific PEG variants based on desired product characteristics and skin compatibility. When used appropriately, PEG contributes to improved product performance and enhanced skincare efficacy, making it a valuable ingredient in many cosmetic formulations.
