PEG 90M

Description

PEG 90M, also known as Polyethylene Glycol 90M, is a high molecular weight polymer used extensively in skincare and cosmetic formulations. This synthetic ingredient functions primarily as a thickening agent, emulsion stabilizer, and viscosity modifier. Its large molecular structure allows it to form a protective film on the skin, contributing to improved moisture retention and a smooth, silky feel.

In skincare products, PEG 90M enhances texture and spreadability, making creams and lotions easier to apply evenly. Its water-binding properties help maintain product consistency and prevent separation of ingredients over time. This versatile compound is particularly useful in leave-on formulations, such as moisturizers and serums, where it can provide a long-lasting hydrating effect.

PEG 90M is generally considered safe for topical use and is well-tolerated by most skin types. However, as with all polyethylene glycol compounds, it may potentially enhance the penetration of other ingredients, which formulators must consider when developing products. Its non-irritating nature makes it suitable for sensitive skin formulations, though individuals with compromised skin barriers should exercise caution. When used appropriately, PEG 90M contributes significantly to product stability, texture, and overall efficacy in skincare applications.
