Hydroxyethyl cellulose (HEC) is a kind of non-ion aqueous agglomerate, white or yellowish fluid powder, no odor no taste, soluble in both hot and cool water, dissolving faster with temperature rising, usually insoluble in most organic solvents, with good PH stability, its viscosity varies little within PH2-12.HEC offers strong water affinity and water-holding, its water solution has surfactant ability, and its thick product owns high plasticity. It can be made into colorless, transparent, aqueous film with medium strength that is hard to pollute, is not to be affected by light. HEC after surface treatment disperses in water does not conglomerate, but dissolving slowly; fast dissolving may be got by adjusting PH to 8-10.
