Hydroxypropyl methyl cellulose is a kind of white or slightly yellowish powder, odorless, tasteless, and non-toxic. The product can be dissolved in cold water to form a transparent viscous solution. The aqueous solution of this product has surface activity so that it has emulsification, protective colloids and relative stability. As the product is non-ionic, and in the preparation process can be effectively purified by washing with hot water, it has a very low ash content.Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether made from natural high polymer cellulose by series of chemical processing. It is odorless, tasteless and non-toxic white powder, which could be dissolved in cold water to form transparent and thick solution. It possess thickening, binding, dispersing, emulsifing, film forming, suspending, absorbing, gelling, surface activity, water maintaining and protective colloid properties.

The HPMC Properties:

 

1) appearance : HPMC cellulose is a non-ionic cellulose ether, white off-white powder or particle, odorless and tasteless, soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone according to the degree of substitution, actually insoluble in hot water, ethylene glycol and toluene.HPMC is dissolved in the mixture of 10% methanol and 90% dichloromethane to form a colloidal solution.

2) HPMC solution has high surface activity, high transparency and stable performance.When heated at a certain temperature, the solution becomes cloudy or forms a flocculating gel.However, the solution becomes clear when it cools.Different types of HPMC have different gelation temperatures.Solubility varies with viscosity.The lower the viscosity, the higher the solubility.Different types of HPMC have different properties, and their solubility in water is not affected by pH value.

3) particle size :80 mesh qualified rate 100%.

4) apparent density :0.25-0.70 g/mL(usually about 0.5 g/mL), specific density: 1.26-1.31mL.

5) color changing temperature :190-200℃;Carbonization temperature: 280-300 °C.

6) surface tension :42-56 dyn/cm(2% aqueous solution).

7) the higher the content of methoxy in HPMC, the lower the gelation temperature, the higher the water-solubility and surface activity.

8) HPMC also has the characteristics of thickening, pH stability, water retention, good film formation, good dispersion and adhesion
