PEG-45

Description

PEG-45 is a polyethylene glycol derivative widely used in cosmetic and personal care formulations. This synthetic polymer functions primarily as an emollient, emulsifier, and thickening agent. With a molecular weight of approximately 2,000 daltons, PEG-45 is a versatile ingredient that enhances product texture and improves the stability of various skincare and haircare formulations.

In skincare products, PEG-45 helps to create smooth, easily spreadable textures while providing a light moisturizing effect. It aids in the even distribution of active ingredients and can enhance the penetration of other beneficial compounds into the skin. As an emulsifier, it helps to blend oil and water-based ingredients, creating stable emulsions that resist separation over time.

PEG-45 is generally considered safe for topical use and is well-tolerated by most skin types. However, individuals with sensitive skin should perform patch tests before regular use. While it offers functional benefits in formulations, PEG-45 does not provide significant direct skincare benefits on its own. Its primary role is to improve product performance and user experience by enhancing texture, stability, and the delivery of other active ingredients.
