3.2.1.1 Cellulose
Hydroxypropyl helps increase the water solubility of HPMC, making it easier to incorporate into formulations and ensuring better bioavailability of the active ingredients. Methyl groups, on the other hand, affect the viscosity and film-forming properties of HPMC, which can control the texture and appearance of the final product.
(3) Sustained release agent:
In some vitamin preparations, sustained release of the active ingredient is required to prolong its absorption in the body. HPMC can be used to control the release rate of vitamins, ensuring stable, sustained release over time.
