DEFINITION
Hypromellose Acetate Succinate is a mixture of acetic acid and monosuccinic acid esters of hydroxypropyl methylcellulose. It contains NLT 12.0% and NMT 28.0% of methoxy groups (–OCH3), NLT 4.0% and NMT 23.0% of hydroxypropoxy groups (–OCH2CHOHCH3), NLT 2.0% and NMT 16.0% of acetyl groups (–COCH3), and NLT 4.0% and NMT 28.0% of succinoyl groups (–COC2H4COOH), calculated on the dried basis.
