Specification :
NATROSOL 250 hydroxyethylcellulose ( HEC) is a series of off-white powders that are easily dispersed and
dissolved in cold or hot water, to produce solutions of varying viscosities. Chemically, it is cellulose of short to
very long chain length that has been etherified to a hydroxyethyl ether to achieve an optimum balance of
properties. NATROSOL 250 is used as a viscosity and rheology modifier, protective colloid, water retention
agent, stabilizer, and suspending agent, particularly in those applications where a nonionic material is desired.
