peg 32

Description

Polyethylene Glycol 32 (PEG-32) is a synthetic polymer widely used in skincare and cosmetic formulations. This versatile ingredient functions primarily as an emollient, humectant, and solubilizer. PEG-32 has a molecular weight of approximately 1,450 daltons, allowing it to penetrate the stratum corneum and enhance the delivery of other active ingredients.

In skincare products, PEG-32 helps to improve texture and spreadability while providing mild moisturizing properties. It attracts and retains water, contributing to skin hydration without feeling heavy or greasy. As a solubilizer, PEG-32 aids in dissolving and stabilizing other ingredients, ensuring uniform distribution throughout the formulation.

This ingredient is generally well-tolerated by most skin types and is considered safe for use in cosmetics by regulatory bodies. However, individuals with sensitive skin should perform patch tests, as some may experience mild irritation. PEG-32 is often found in cleansers, moisturizers, and serums due to its ability to enhance product performance and stability.

When formulating with PEG-32, it's important to consider its potential to enhance penetration of other ingredients, which can be both beneficial and potentially sensitizing depending on the overall formulation.
