Methyl cellulose

Details:

Cellulose ether series -------------------------------------------------------------------------------- Pharmaceutical & food grade Methyl Cellulose (MC), Hydroxypropyl Methyl Cellulose (HPMC) Product properties and applications This product is non-ionic cellulose ether, having salt resistance, surface activity, thermal gelation property, PH stability, water retention, film formation, adhesion and other properties. As a multi-purpose pharmaceutic adjuvant it can be used as thickener, dispersant, emulsifier and film-former. Used for film coating, adhesive in tablets, it can significantly increase the drug solubility, and enhance waterproof of tablets. It can be also used for suspension agent, ophthalmic preparations, controlling release agents such as skeleton floating tablets together. It can be directly used for food as emulsifier, binder, thickener and stabilizer; and it also can be used directly as a food packaging material. Porduct specification Meet the China Pharmacopoeia NF standard, United States Pharmacopoeia USP standard, the European Pharmacopoeia EP standard. 1.
