White powder Gelatining agent HPMC E5 CAS 9004-65-3 for Tablet Coating
HPMC Hydroxy Propyl Methyl Cellulose is a kind of cold-water-soluble non-ionic polymer. It has different solubility, surface activity, gelatinization based on different methoxyl substitution degrees and viscosities. Currently HPMC Hydroxy Propyl Methyl Cellulose is one of the most popular pharmaceutical excipients all around the world. It can be used as tablet binder, disintegrating agent, controlled release agent, film-forming agent etc.. Its aqueous solution or alcoholic solution, as the binder, can form a layer of thin film on the particle surface, which can help improving the stability of the medicines. And it is especially good for some unstable medicines. Generally viscosity 5cps can be used for tablet coating, 15cps to 50cps be used as the binder and more than 100cps can be used for controlled releasing. Common concentration of HPMC Hydroxy Propyl Methyl Cellulose for binder should be 2%-5%.
HPMC is white powder with tasteless, odourless and non-toxic. In human body it has no change and is eliminated from the body completely. It is easily dissoved in water and form a kind of colourless and transparent viscous liquid.

The production process of HPMC is like this, purified cotton → add caustic soda → solvent treatment → etherification → water scrubbing → centrifugalization → dry. In food industry, HPMC can be used as thickening agent, stabilizer, emulgator and gelatinizing agent.
HPMC, as hydrophilic gel matrix material, is the most popular controlled released preparation now. The matrix will expand with water or digestive juic and then form gel barrier to control the release of medicines. Controlled release tablets with HPMC as the matrix has a simple production technology and it has a very good effect of controlled release for different medicines. Besides, its physical properties has no relationship with PH at a range of physiological condition. So it is a perfect and widely used excipient of controlled release medicine.
