GLYCERETH-18

Description

Glycereth-18 is a polyethylene glycol (PEG) ether of glycerin, functioning primarily as an emollient and humectant in skincare and cosmetic formulations. This synthetic ingredient is derived from the ethoxylation of glycerin, resulting in a compound with enhanced water-binding properties.

In skincare products, Glycereth-18 helps to improve moisture retention in the skin by forming a protective barrier on the surface. This action helps to reduce transepidermal water loss and maintain skin hydration. Its emollient properties contribute to a smoother, softer skin texture upon application.

Glycereth-18 is particularly valued for its ability to enhance the spreadability and texture of formulations, making products more pleasant to use. It also serves as a solubilizer, helping to incorporate oil-soluble ingredients into water-based formulations.

This ingredient is generally well-tolerated by most skin types and is considered safe for use in cosmetics. However, as with all PEG compounds, there is a slight risk of contamination with potentially harmful byproducts during manufacturing, necessitating careful sourcing and quality control.

Glycereth-18 is commonly found in moisturizers, serums, and other leave-on skincare products, where its hydrating and texture-enhancing properties are most beneficial.
