HPMC introduction:
Function:
Thickening,dispersing,emulsifying, excipients.
Chemical hpmc advantage
1. Water soluble and thickening ability: this product can soluble in cold water, form transparent sticky solution. In organic
solvent of dissolved: because it contains a certain amount of hydrophobic methoxyl, therefore, this product can soluble in
some organic solvent, also can soluble in water and organic mixed solvent.
2. Hydroxypropyl methyl cellulose (HPMC) salt resistance: because in this product are ion and the polyelectrolyte,
therefore, it is metal salt or organic electrolyte aqueous solution is stable.
3. Surface activity: HPMC for daily chemical aqueous solution has the surface activity, make its have emulsification,
protective colloid and relative stability.
4. Low ash content: because in this product are ionic, in preparation process can use hot water washing effectively
refined, so its ash content is very low.
5. PH stability: HPMC aqueous solution viscosity in PH3.0-11.0 range are more stable.
6. Water retention effect: because in this product is hydrophilic and its solution is of high viscosity. Film-7,forming property:
HPMC can generate strong pliable, transparent sheet, has the good oil resistance to ester performance.
