Glycereth-18

Description

Glycereth-18 is a polyethylene glycol (PEG) derivative of glycerin, functioning as an emollient and humectant in skincare and cosmetic formulations. This versatile ingredient is created through the ethoxylation process, where ethylene oxide is added to glycerin, resulting in a compound with enhanced water-binding properties.

As a humectant, Glycereth-18 attracts and retains moisture in the skin, helping to maintain hydration levels and improve overall skin texture. Its emollient properties contribute to a smooth, silky feel when applied topically, making it a popular choice in lotions, creams, and other personal care products.

Glycereth-18 is particularly useful in formulations where a less greasy or tacky feel is desired, as it provides moisturization without leaving a heavy residue. Its molecular structure allows for efficient penetration into the skin's upper layers, enhancing the delivery of other active ingredients.

This compound is generally well-tolerated by most skin types and is considered safe for use in cosmetic applications. However, as with any PEG-based ingredient, individuals with sensitive skin should perform a patch test before regular use to ensure compatibility.
