A na-eji hydroxypropylmethylcellulose (HPMC), nke a makwaara dị ka hydroxypropylmethylcellulose, nke a na-eji na ngwaahịa anyị emepụtara. Ugbu a, n'oge gara aga, enwere ike ịdepụta ọdịnaya ndị a na labelụ:

Mana FDA gbanwere ụkpụrụ ịde aha iji chọọ ka edepụta okpu onye anaghị eri anụ dị ka hydroxypropyl methylcellulose ma ọ bụ hydroxypropyl methylcellulose.
Ya mere, ekwesịrị iburu n'uche na hydroxypropyl methylcellulose phthalate (HPMCP) bụ ihe dị iche na HPMC kpọmkwem (hydroxypropyl methylcellulose ma ọ bụ hydroxypropyl methylcellulose). Ee, okwu a na-eweta ụwa dị iche.
Dị ka tebụl nkọwapụta nke onye na-emepụta okpu anụ anaghị eri anụ si dị:
HPMC bụ ngwaahịa osisi nke bụ ụdị cellulose dị ọcha nke ewepụtara na pulp osisi. Dị ka Mgbakwunye I nke EU Regulation No. 1169/2011 na-enye nri ozi na-eri, HPMC bụ nkewa dị ka "fiber" na kọwaa dị ka a polymer nke carbon mmiri ogige na atọ ma ọ bụ karịa monomer nkeji, nke na-adịghị gbarie ma ọ bụ etinye obi gị dum na obere eriri afọ mmadụ.
Agbanyeghị, ụzọ nnwale ụlọ nyocha ugbu a maka eriri nri, dị ka AOAC 985.29, anaghị achọpụta HPMC nke ọma dị ka eriri nri. Otú ọ dị, HPMC bụ ihe oriri carbohydrate polima, a dietary eriri nwere uru physiological mmetụta, nke ndị ọkà mmụta sayensị nabatara nke ọma, ya mere enwere ike ikwupụta ya n'afọ ofufo.
Maka ndị na-amụtabeghị ọtụtụ kemistri
Cellulose bụ agbụ nke carbon, hydrogen, na oxygen mejupụtara, nke na-enwekarị narị otu narị ruo puku kwuru puku carbon, hydrogen, na ụdọ oxygen ọnụ.
Hydroxyl - pụtara na e nwere oxygen na hydrogen ejikọrọ ebe na cellulose yinye, kama naanị hydrogen.
Propyl - pụtara na e nwere agbụ n'akụkụ n'otu ebe na yinye, ebe atọ carbon carbon gbara ya gburugburu.
Methyl - Otu ihe dị ka propyl, mana ọ bụghị carbon atọ, mana naanị otu.
