PEG-22 is widely used in the cosmetics and personal care industry as an emulsifier, thickener, and stabilizer. It helps to blend water and oil-based ingredients in products like creams, lotions, and serums, ensuring a smooth and consistent texture. Additionally, it enhances the moisturizing properties of skincare formulations by retaining hydration on the skin. In haircare products, it improves the spreadability and conditioning effects, leaving hair soft and manageable. Its non-irritating nature makes it suitable for sensitive skin formulations. PEG-22 is also utilized in pharmaceutical applications as a solubilizing agent, aiding in the delivery of active ingredients in topical treatments.
