HEC consists of two parts: one is cellulose, and the other is
hydroxyethyl branched chain. Hydroxyethyl cellulose is
made by first reacting purified cellulose with sodium
hydroxide to generate alkaline cellulose colloid, and then
adding ethylene oxide to the colloid.
The substitution value of HEC is between 1.5 and 2.5. It is
easily soluble in hot water and cold water, provides a
solution with broad viscosity, and can accept the
electrolyte concentration in the solution.
