ʻO Hypromellose, i kapa ʻia ʻo hydroxypropyl methylcellulose (HPMC), he polymer synthetic i loaʻa mai ka cellulose.Hana ʻia ia ma ke kemika hoʻololi ʻana i ka cellulose kūlohelohe i loaʻa mai ka pulp lāʻau a i ʻole nā ​​pulu pulupulu ma o kahi kaʻina i kapa ʻia ʻo etherification.Ma kēia kaʻina hana, mālama ʻia nā fiber cellulose me ka hui pū ʻana o ka propylene oxide a me ka methyl chloride, kahi e alakaʻi ai i ka hoʻohui ʻana o nā pūʻulu hydroxypropyl a me methyl i nā molekule cellulose.

ʻO ka huahana hopena he polymer hiki ke hoʻoheheʻe ʻia i ka wai i hoʻohana ʻia i nā ʻano hana like ʻole, me nā lāʻau lapaʻau, nā mea hoʻonaninani, nā huahana meaʻai, a me nā mea hoʻohui meaʻai.Loaʻa ka Hypromellose i nā māka like ʻole, me nā ʻano kaupaona molekala a me nā degere o ka hoʻololi ʻana, ma muli o ka hoʻohana i manaʻo ʻia.

ʻO ka holoʻokoʻa, ua manaʻo ʻia ka hypromellose he mea palekana a ʻae maikaʻi ʻia ke hoʻohana ʻia e like me ke kuhikuhi ʻana.Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he mea hoʻopili, kahi mānoanoa, a me kahi stabilizer i nā huahana he nui a ua waiwai ʻia no kona hiki ke hoʻomaikaʻi i ke kūpaʻa huahana, hoʻonui i ka viscosity, a hoʻonui i ka hana huahana.
