Hydroxy Propyl Methyl Cellulose, Brand Name : BOTAI

We are offering hydroxy propyl methyl cellulose,
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.
