PEG-115M

Description

PEG-115M is a high molecular weight polyethylene glycol (PEG) derivative commonly used in skincare and cosmetic formulations. This synthetic polymer functions primarily as an emollient, humectant, and viscosity-controlling agent. With an average molecular weight of approximately 115,000 Daltons, PEG-115M forms a protective film on the skin's surface, helping to reduce transepidermal water loss and maintain skin hydration.

In skincare products, PEG-115M enhances texture and improves spreadability, creating a smooth, non-greasy feel upon application. Its humectant properties allow it to attract and retain moisture, contributing to increased skin hydration. As a viscosity modifier, it helps stabilize emulsions and suspensions, ensuring consistent product performance.

PEG-115M is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations. However, individuals with sensitive skin should perform patch tests before regular use. This ingredient is often found in moisturizers, serums, and other leave-on skincare products where long-lasting hydration and improved texture are desired. Its high molecular weight limits skin penetration, making it primarily a surface-active ingredient that works to enhance the overall feel and efficacy of skincare formulations.
