PEG-75

Description

PEG-75 is a polyethylene glycol (PEG) compound widely used in skincare and cosmetic formulations. This synthetic polymer acts as an emulsifier, solubilizer, and humectant, playing a crucial role in product stability and performance. With a molecular weight of approximately 3,400 Daltons, PEG-75 is composed of 75 ethylene oxide units, giving it unique properties that benefit various skincare applications.

As an emulsifier, PEG-75 helps blend oil and water-based ingredients, creating stable emulsions in creams and lotions. Its solubilizing properties aid in incorporating oil-soluble ingredients into water-based formulations, enhancing product versatility. The humectant properties of PEG-75 attract and retain moisture, contributing to improved skin hydration.

PEG-75 is generally considered safe for topical use and is compatible with most skincare ingredients. It helps improve the texture and spreadability of products, enhancing user experience. While it's synthetic in nature, PEG-75 is non-irritating for most skin types and doesn't clog pores. Its molecular size typically prevents it from penetrating deep into the skin, primarily functioning on the surface level to maintain product integrity and deliver other active ingredients effectively.
