It could dissolves at ordinary temperature in water or in any organic solvents,such as absolute methanol, ethanol,isopropanol propylene glycol and methylene chloride,also inacetone,chloroform,toluene,or cellosolves. The solution is very clear and transparent.
H-HPC is a highly thermoplastic substance,and shows and excellent film forming property. The film obtained is very tough. Ash content is exceedingly low, so that the product has excellent binding property,stabilizing property for viscosity-increasing emulsions and in dispensability .
H-HPC sows no medicinal action by itself,has no toxicity and is physiologically harmless.
H-HPC is chemically inert,so that is hardly reacts with other reagents
The addition of antifungal agents is not necessary when H-HPC is used.
Equilibrium moisture content of H-HPC is low
Use as binders: in the pharmaceutical field, as a binder for tablets,granules and fine grains or as the paste of ointments. It is used in and amount of 1% to 5% by weight of the drug.
As film coating agents: H-HPC has an excellent film-forming property.
H-HPC is used as gelation agents for water and alcohols.
Package,storage,transportation
It is packed in fiber drum and lining with polyethylene film bag. Net weight 25kg per drum. Direct sunshine and raining,moisture must be avoided .
