Hydroxypropyl Methylcellulose(HPMC)
VAMCELL® HPMC Hydroxy Propyl Methyl Cellulose
VAMCELL® is our registered trademark of Hydroxy Propyl Methyl Cellulose.
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 rater-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.

Hydroxypropyl methylcellulose (HPMC) is a derivative of Methyl cellulose. HPMC is a non-ionic cellulose ether made from natural renewable polymer, such as cotton or wood pulp. It is an odourless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution.

Hydroxypropylmethylcellulose is a type of non-ionic cellulose mixed ether. It is a semi synthetic, inactive, viscoelastic polymer commonly used as a lubricant in ophthalmology, or as an excipient or shaping agent in oral medicine.
Appearance: White or almost white fibrous or granular powder
Stability: Solids are flammable and incompatible with strong oxidizing agents.
Used as a thickener, dispersant, binder, excipient, oil resistant coating, filler, emulsifier, and stabilizer in the textile industry. It is also widely used in industries such as synthetic resins, petrochemicals, ceramics, papermaking, leather, pharmaceuticals, food, and cosmetics.
Pharmaceutical industry: coating materials; Membrane material; Control rate polymer materials for sustained-release formulations; Stabilizer; Suspension aids; Tablet adhesive; Thickener.
