PEG-90

Description

PEG-90 is a polyethylene glycol compound widely used in skincare and cosmetic formulations as an emollient, solvent, and viscosity-controlling agent. This synthetic polymer is derived from ethylene oxide and has an average molecular weight of approximately 4,000 daltons. PEG-90 is water-soluble and hygroscopic, meaning it can attract and retain moisture from the surrounding environment.

In skincare products, PEG-90 functions as a humectant, helping to maintain skin hydration by drawing water from the atmosphere and deeper skin layers to the surface. It also acts as an effective solubilizer, aiding in the dissolution of other ingredients and improving the overall stability of formulations. PEG-90's viscosity-controlling properties contribute to the texture and spreadability of products.

This ingredient 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. PEG-90 is often found in moisturizers, serums, and cleansers, where it enhances product consistency and aids in the delivery of active ingredients. Its versatility and compatibility with various cosmetic ingredients make it a valuable component in modern skincare formulations.
