Propylene Glycol Ether of Methylcellulose; Modified Cellulose, HPMC
INS: 464 CAS: [9004-65-3]

DESCRIPTION
Hydroxypropyl Methylcellulose occurs as a white to off-white, fibrous powder or as granules. It is the propylene glycol ether of methylcellulose in which both the hydroxypropyl and the methyl groups are attached to the anhydroglucose rings of cellulose by ether linkages. Several product types are available that are defined by varying combinations of methoxyl and hydroxypropoxyl content. It is soluble in water and in certain organic solvent systems. Aqueous solutions are surface active, form films upon drying, and undergo a reversible transformation from sol to gel upon heating and cooling, respectively.
Function: Thickening agent; stabilizer; emulsifier.

REQUIREMENTS
Identification:
A. Add 1 g of sample to 100 mL of water. It swells and disperses to form a clear to opalescent, mucilaginous solution, depending on the intrinsic viscosity, which is stable in the presence of most electrolytes.
B. Add 1 g of sample to 100 mL of boiling water, and stir the mixture. A slurry forms that when cooled to 20C, dissolves to form a clear or opalescent, mucilaginous solution.
C. Pour a few milliliters of the solution prepared for Identification Test B onto a glass plate and allow the water to evaporate. A thin, self-sustaining film forms.
Assay for Hydroxypropoxyl Groups: Between a minimum of 3.0% and a maximum of 12.0% of hydroxypropoxyl groups (-OCH2CHOHCH3), within the range claimed by the vendor for any product type.
Assay for Methoxyl Groups: Between a minimum of 19.0% and a maximum of 30.0% of methoxyl groups (-OCH3), within the range claimed by the vendor for any product type.
Lead: Not more than 3 mg/kg.
Loss on Drying: Not more than 5.0%.
Residue on Ignition: Not more than 1.5% for products with viscosities of 50 centipoises or above; not more than 3.0% for products with viscosities below 50 centipoises.
Viscosity: The viscosity of an aqueous solution containing 2 g of sample per 100 g of solution is not less than 80.0% and not more than 120.0% of that stated on the label for viscosity types of 100 centipoises or less, and not less than 75.0% and not more than 140.0% of that stated on the label for viscosity types higher than 100 centipoises.
