Natrosol 250 HR Hydroxyethylcellulose, PC Grade is a nonionic water-soluble polymer. This white, free-flowing granular powder can be used in a variety of applications, including hair conditioner, liquid soaps, shave gels and foams, toothpaste (high salt), wipes (baby and adult), makeup/mascara, AP/Deodorant solids, and lubricant gels. Solutions of Natrosol HEC are pseudoplastic or shear-thinning. As a result, personal care products formulated with Natrosol HEC dispense rich and thick from the container, but spread easily on hair and skin.
