Hydroxypropyl Methyllose /Methyllose
HS Code: 3912,900
CAS: 9004-65-3
Composition and chemical structure:
Hydroxypropyl methyl lose is a kind of white or slightly yellowish powder, odorless, tasteless, and non-oduct 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. Stability: the aqueous solution viscosity of this product is relatively stable in the range of 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 methyllose products can fully meet the standards for use of medicine, food, construction and personal care products.

sical and chemical properties
*Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
*Charring temperature: 280-300℃.
*Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
*Real specific gravity:1.26-1.31.
*Browning temperature: 190-200℃.
Surface tension:(2% water solution) .
*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 Methyllose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.
Packing and Storage
Standard Packing: In 25kg bags out HDPE bags with inner plastic bags. Store it in a cool, dry place below 30degree and protected against humidity and pressing, since the goods is thermoplastic, storage time should not exceed six months.
