PEG-200, also known as polyethylene glycol 200, is a polyethylene glycol polymer used in the cosmetics and pharmaceutical industry. It is water soluble and has emollient and moisturizing properties. PEG-200 is used as a texture agent, emulsifier and solubilizer in skin care products, hair products, creams, lotions and gels. It helps to improve the texture, consistency and stability of formulations, while promoting the penetration of active ingredients. PEG-200 is well tolerated by the skin and is often used as an alternative to irritating ingredients.
