hydropropylcellulose (HPC) is a non ionic water-soluble cellulose ether with a versatile combination of
properties. It combines organic solvent solubility, thermo plasticity, and surface activity with the thickening and
stabilizing properties of other water-soluble cellulose polymers. Klucel is a white powder with no odor or taste. It is available in various chain lengths, which means different viscosity.
Properties and Uses
Klucel®is soluble in many polar organic solvents and in water below 38°C, but is insoluble in water above 45°C.
Klucel® is highly surface-active, with low surface and interfacial tensions of solutions. In films and coatings, Klucel® is heat-sealable, and it is extremely flexible without plasticizers. The versatility of Klucel® is apparent in a wide variety of pharmaceutical applications, including tablet coatings, controlled-release products, encapsulation, tablet binding and as a suspension aid. A solution in non-aqueous/denatured ethyl alcohol enables a water spot-free gluing of wall-paper or stabilization of paints.
