Description
PEG (polyethylene glycol) is a group of synthetic compounds that are widely used in cosmetic products due to their ability to retain moisture, improve the texture of products, mix fatty and aqueous components, and enhance the penetration of actives. PEGs come in different sizes and functions, depending on their molecular weight and structure. In cosmetics, PEGs act as emulsifiers, moisturizers, softeners, conditioners, and solubilizers (helping to dissolve water-insoluble substances). They are added to creams, serums, shampoos, gels, cleansers, toothpastes, and more. PEGs can also improve the sensory characteristics of a product, making the texture pleasant, light, and non-sticky. In some formulas, they act as carriers, improving the delivery of other ingredients into deeper layers of the skin.
