High Water Retention Hydroxypropyl Cellulose for Coatings

Uses of different types of Hydroxypropyl Cellulose
Low-substituted Hydroxypropyl Cellulose：
Low-substituted Hydroxypropyl Cellulose (L-HCC) is mainly used as tablet disintegrating agent and binder. The characteristics of using low-substituted hydroxypropyl cellulose (L-HCC) as binder and disintegrating agent are: easy to press molding, strong applicability, especially the tablets which are not easy to be formed, and the tablets which have large plasticity and brittleness can be improved in hardness and appearance and brightness by adding low-substituted hydroxypropyl cellulose (L-HCC), and also can make the tablets disintegrate quickly. HPC) can improve the hardness and brightness of the tablets and also make the tablets disintegrate rapidly, even if the hardness of the tablets reaches 13kg without crumbling, the disintegration only takes ten minutes to improve the intrinsic quality of the tablets and enhance the therapeutic efficacy; tablets made of low-substituted hydroxypropylcellulose (L-HPC) are kept for a long time and their disintegration will not be affected.
As a tablet binder, generally add 5-20% in wet granulation, 5-20% in powder direct tablet pressing, as a tablet disintegrating agent, the dosage of 2-10%, generally 5%, plus and plus can be added, depending on the specific prescription.
Low-substituted Hydroxypropyl Cellulose (L-HPC) can also be used as food additives, emulsifiers, stabilizers, suspending agents, thickening agents, film-forming agents in the food industry, used in beverages, pastries, jams and other manufacturing.
Low-substituted Hydroxypropyl Cellulose (L-HCC) is also used in the cosmetic industry, as creams, shampoos, lotions and other cosmetic manufacturing.
Highly substituted Hydroxypropyl Cellulose：
1. used as a viscous agent: in the pharmaceutical field, this product is mainly used as a binder, such as as tablets, granules, fine particles of the binder.
2, used as film coating materials for tablets, HPC has excellent film-forming properties, the film is tough and flexible, and plasticizers can be compared with the high and low, by mixing with other anti-wet coating agent, can further improve the performance of the film.
3, used as elixir thickener, detergent additives and emulsion stabilizer. 4, can be used as a skeleton material for the preparation of the film.
4. can be used as a skeleton material to prepare the skeleton of slow-release tablets, slow-release pills and double-layer slow-release tablets.
5. Used as gel agent in ethanol occasion and as ointment base material.
