Hpmc Hydroxy Propyl Methyl Cellulose, Brand Name : BOTAI

Hydroxypropyl Methyl Cellulose (MHPC)
VAMCELL™ MHPC Hydroxy Propyl Methyl Cellulose
VAMCELL™ is our registered trademark of Hydroxy Propyl Methyl Cellulose.
Introduction:
VAMCELL™ HPMC is made by propylene oxide, methyl chloride with alkali-cellulose after a chemical process called Etherification under rigidly controlled conditions. The resultant nonionic polymer is purified, dried and ground to a fine white powder, this water-insoluble cellulose is turned into water-soluble nonionic polymer, HPMC is a good film-former and varies somewhat in physical and chemical properties. HPMC is quite hydrophilic and readily soluble in cold water.
