HPMC bụ hydropyylthyl methyl cellulose, nke bụ ihe na-abụghị ionic agwakọta nke a na-ajuru eto akpụ na methylich chloride dị ka nke mmeghachi omume. Ogo nke dochie anya ya bụ 1.2 ruo 2.0. Njirimara ya dịgasị iche dabere na ọnụ ọgụgụ Methoxyl na ọdịnaya hydroxypypyl.
(1) hydroxypylthylthyl na-agbanye mmiri na mmiri oyi, mana ọ ga-ezute ihe isi ike na mmiri ọkụ. Ma ọnọdụ okpomoku ya na mmiri ọkụ dị elu karịa nke methy cellulose. A na-akwalitekwa mmiri oyi na-akwalite ya na methy cellulose.
(2) viscosity nke hydroxylthylthyl Methylcellose bụ ihe dị oke ibu nke oke mmiri ya, na ibu oke molecular, onye dị elu na viscosity.
