Introduction and application of CAS 9004-64-2|Hydroxypropyl cellulose
Low-substituted hydroxypropylcellulose (L-HPC) is mainly used as a tablet disintegrant and binder. The characteristic of using low-substituted hydroxypropylcellulose (L-HPC) as a binder and disintegrant is that it is easy to press and form. , strong applicability. As a tablet binder, 5~20% is generally added when wet granulation, and 5~20% is used when the powder is directly compressed into tablets. As a tablet disintegrating agent, the dosage is 2~10%, usually 5%, and is added internally. Any addition is possible, depending on the specific prescription. Low-substituted hydroxypropylcellulose (L-HPC) can also be used as a food additive. It is used as an emulsifier, stabilizer, suspending agent, thickener, and film-forming agent in the food industry, and is used in beverages, pastries, jams, etc. It is also used in the daily chemical industry for the manufacture of cosmetics such as creams, shampoos, and lotions.
White or slightly yellow or gray granules or fibrous powder. Odorless, tasteless, flammable, thermoplastic. Swells in water to form a transparent to milky white viscous colloidal solution. Soluble in ethanol, insoluble in ether. Insoluble in water above 38°C. Uses emulsifier, coating agent, protective colloid, stabilizer, suspending agent, thickener. In Japan, 70% is used in medicine as tablet adhesives, film coatings, etc.
use
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, coatings, and ink industries.
1. Used as a viscosity agent: In the pharmaceutical field, this product is mainly used as a binder, such as as a binder for tablets, granules, and fine granular materials. It is generally 1-5% of the weight of the drug. Choose RT- L or RT-J type.
2. Used as film coating material for tablets. HPC has excellent film-forming properties, and the resulting film is tough and elastic, which can be compared with plasticizers. By mixing with other temperature-resistant coating agents, the performance of the film can be further improved. Generally, RT-L type is selected.
3. Used as a thickener for elixirs, an addition to lotions and a stabilizer for emulsions. Generally, RT-M type is selected. 4. It can be used as a matrix material to prepare matrix sustained-release tablets, sustained-release pellets and double-layer sustained-release tablets. RT-M type is generally used.
5. Used as a gel in ethanol situations and as an ointment base
