UNICEL HEC 30K (HYDROXYETHYL CELLULOSE)
GENERAL INFORMATION
UNICEL HEC 30K is an odorless, white to off-white powder obtained by etherification of cellulose with ethylene oxide. It dissolves easily in cold and hot water, forming clear viscous solutions. It is widely used to improve viscosity, stability, and texture in paints, personal care products, and adhesives.
