Hydroxypropyl MethylCellulose /MethylCellulose

HS Code: 3912,900

CAS: 9004-65-3

Composition and chemical structure:

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. PH Stability: the aqueous solution viscosity of this product is relatively stable in the range of PH 3.0—11.0. 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 methylcellulose products can fully meet the standards for use of medicine, food, construction and personal care products.

Specifications

Physical and chemical properties

*Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.

*Charring temperature:

*Bulk density: 0.25-0.70 g/cm³ (Usually around 0.5 g/cm³ )

*Real specific gravity:

*Browning temperature: 190-200℃.

Surface tension:(2% water solution) 42-56dyn.cm.

*Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.
