HPC hydroxypropyl cellulose
SidleyCel® H-HPC can be used as a binder in pharmaceutical field such as tablet and particle binder, which can increase the stability and hardness of tablets. H-HPC has excellent film forming property and film can be tenacious and elastic. It's also an excellent film coating material.
Highly substituted hydroxypropyl cellulose (H-HPC) is a thermoplastic, non-ionic cellulose ether that is soluble in water and many organic solvents. Aqueous solutions have moderate surface activity and produce thickening and stabilizing effects in water-dispersed systems. At very high concentrations, HPC exhibits liquid crystal properties.
Water soluble - soluble in cold water, the aqueous solution is heated to 40 ~ 45ºC turbidity point, polymer begins to precipitate out of the solution, if there are other components in the solution will affect its turbidity point.
Organic solvent - HPC can also be dissolved in a variety of organic solvents to obtain the flow characteristics of the solution, such as ethanol, glycol and fibrinolytic agent, can also be dissolved in organic solvent-water system.
Pseudoplasticity - HPC solution has pseudoplastic flow characteristics viscosity increases rapidly with the increase of concentration, at a high concentration, HPC presents liquid crystal characteristics. Its solids can be molded or extruded above 100 ° C.
Anti-enzyme - has a strong anti-enzyme ability, excellent resistance to biodegradation.
Water absorption - has a low equilibrium moisture content.
