HEC is a modified cellulose polymer that is commonly used in various industries, including cosmetics and personal care. In skincare and beauty products, HEC serves as a thickening and gelling agent. It helps improve the texture and consistency of formulations such as creams, lotions, and gels. Additionally, HEC may contribute to the overall stability and viscosity of the product, enhancing its performance and user experience. Always refer to the specific product label for detailed information on its inclusion and purpose in a particular cosmetic product.
