KLUCEL H CS has excellent film-forming properties and thickens non-aqueous systems and provide lubricious skin feel. Klucel™ CS Grade is a nonionic, water-soluble cellulose ether with a versatile combination of properties. It combines solubility in aqueous and polar organic solvents, thermoplasticity, and surface activity with the thickening and stabilizing properties of other water-soluble cellulose polymers. HPC films are flexible without plasticizers and non-tacky at high humidity.
