PEG-80 STEARATE

Description

PEG-80 Stearate is a versatile emulsifying agent widely used in cosmetic and personal care formulations. This synthetic ingredient is derived from the esterification of stearic acid with polyethylene glycol (PEG). It functions primarily as an emulsifier, helping to blend oil and water-based components in skincare products, creating stable and uniform formulations.

The "80" in PEG-80 Stearate refers to the average number of ethylene oxide units in the molecule, which influences its hydrophilic-lipophilic balance (HLB). This property makes it effective in creating oil-in-water emulsions, contributing to the smooth texture and easy spreadability of creams and lotions. PEG-80 Stearate also acts as a surfactant, reducing surface tension and enhancing the product's ability to cleanse and foam.

In skincare formulations, PEG-80 Stearate is generally considered safe and well-tolerated by most skin types. It helps improve the stability and shelf life of products while also enhancing their aesthetic qualities. This ingredient is commonly found in moisturizers, cleansers, and various other skincare and cosmetic products, where it plays a crucial role in maintaining product consistency and efficacy.
