natrosol™ 250 pharm hydroxyethylcellulose
chemistry: cellulosics
SDS Link >Natrosol™ pharm HEC grades are non-ionic, water-soluble polymer widely used in pharmaceutical formulations. This product is easily dispersed in cold or hot water to give solutions of varying viscosities and desired properties, though it is insoluble in organic solvents. It is used in solutions and gels to control rheology, in emulsions for high-salt tolerance and surfactant compatibility, and in modified-release matrix tablets where high-viscosity grades provide effective diffusion-limiting release of active pharmaceutical ingredients (API) with low water solubility.
