Name：Hydroxypropylmethyl cellulose phthalate CAS NO.9050-31-1 It is a kind of white or off-white granule solid, no odor. USE: An enteric coating agent is used to protect drugs from degrs dation by gastric acid or to prevent them from causing side effects in the stomach. HPMCP was developed and used originally as an enteric coating agent, its favroable properties have led to extension of its range of applications into other fields, inlcuding sustained release preparations, binders and microcapsule bases, in the above-mentioned applications.HPMCP is usually used alone, but can be used in combination with other polymers, as in the case of the sustained release preparations Specification Test items Specification Viscosity 0.032~0.048 pa.s Residue on Ignition ≤0.2% Water ≤5.0% Chloride ≤0.07% Arsenic ≤2ppm Heavy metals ≤0.001% Free phthalic acid ≤1.0% Phthalyl content 21.0%~35.0% Methoxy 18.0%~22.0% Hydroxypropoxy 5.0%~9.0%
