Usage
White or slightly yellowish or grayish granules or fibrous powder. Odorless and tasteless, flammable, with thermoplasticity. It swells in water to form a transparent to milky white viscous colloidal solution. Soluble in ethanol, insoluble in ether. Insoluble in water when the temperature is above 38℃.
Emulsifiers, coating agents, protective colloids, stabilizers, suspending agents, and thickeners. In Japan, 70% of these are used in the pharmaceutical industry, as tablet binders, film coatings, and other applications.
It is used as a binder and film-forming agent in the pharmaceutical industry, and as a film-forming agent, dispersant, stabilizer, thickener, etc. in the cosmetics, coating, and ink industries.
- Used as an adhesive: In the pharmaceutical field, this product is mainly used as a binder, such as a binder for tablets, granules, and fine granules, generally accounting for 1-5% of the weight of the pharmaceutical. The RT-L or RT-J type is selected.
- Used as a film coating material for tablets. HPC has excellent film-forming properties, and the resulting film is tough and elastic, which can be comparable to plasticizers. By mixing with other Chemicalbook temperature-resistant coating agents, the performance of the film can be further improved. Generally, the RT-L type is selected.
- Used as a thickener for elixirs, an additive for lotions, and a stabilizer for emulsions. Generally, the RT-M type is selected.
- It can be used as a matrix material to prepare matrix sustained-release tablets, sustained-release pellets, and double-layer sustained-release tablets. Generally, the RT-M type is selected.
5. Used as a gelling agent in ethanol occasions and as an ointment base
