PEG/PPG-300/55 COPOLYMER

Description

PEG/PPG-300/55 Copolymer is a synthetic polymer blend composed of polyethylene glycol (PEG) and polypropylene glycol (PPG) units. This versatile ingredient functions as an emollient, surfactant, and viscosity-controlling agent in skincare and cosmetic formulations. Its unique structure allows it to form stable emulsions, making it valuable in creating smooth, easily-spreadable products.

The copolymer's high molecular weight contributes to its film-forming properties, which can help improve product texture and provide a protective barrier on the skin's surface. This barrier effect may assist in reducing transepidermal water loss, potentially enhancing skin hydration. Additionally, PEG/PPG-300/55 Copolymer can act as a solubilizer, aiding in the incorporation of oil-soluble ingredients into water-based formulations.

In skincare applications, this ingredient is often used in moisturizers, serums, and sunscreens due to its ability to enhance product feel and stability. It's generally considered safe for topical use, with low risk of skin irritation. However, as with any synthetic polymer, individuals with sensitive skin should perform patch tests before widespread application. The "300/55" in its name refers to the average molecular weights of the PEG and PPG components, respectively, indicating its specific composition and properties.
