natrosol™ hydroxyethylcellulose (HEC)
chemistry: cellulosics
Natrosol™ hydrdoxyethylcellulose (HEC), a nonionic, water-soluble polymer, is a white, free-flowing granular powder. Solutions of Natrosol™ HEC are pseudoplastic or shear-thinning. Natrosol™ HEC is easily dissolved in cold or hot water to give crystal-clear solutions of varying viscosities. Furthermore, low to medium molecular weight types are fully soluble in glycerol and have good solubility in hydro-alcoholic systems containing up to 60 percent ethanol. Natrosol™ HEC is generally insolbuble in organic solvents.
