Hydroxyethy Cellulose(HEC) is a non-ionic cellulose ether . It is easily dispersed and dissolved in water to produce solution of high viscosity. HEC is used as a viscosity and rheology modifier, protective colloid, water retention agent, stabilizer and suspending agent, particularly in those applications where a non-ionic material is desired. The product has higher and more uniform degree of substitution, improved the enzyme resistance.
