Hydroxypropyl beta-cyclodextrin, e mōhiotia ana ko (2-hydroxypropyl) -β-cyclodextrin, he ngota hauwai i roto i ngā rōpū 2-, 3-, me te 6-hydroxyl o ngā toenga hukahuka i roto i te β-cyclodextrin (β-CD) ka whakakapia e te hydroxypropyl ki te hydroxypropoxy. Ehara i te mea he pai noa te pānga takai o te HP-β-CD ki ngā pūhui maha pērā i te β-CD, engari he pai anō hoki mō te wairewatanga nui ki te wai me te whakapai ake i te tere tuku me te waatea koiora o ngā rongoā kua kapihia i roto i te tinana ora. Hei tāpiri, ko te HP-β-CD he tāpiri rongoā me ngā raraunga haumaru tino whānui kua kohia, ā, kāore he pānga taha kino. Ka taea hoki te whakamahi i te HP-β-CD hei tiaki pūmua me te whakaū.
He paura mā, he paura kore-āhua, he paura tioata rānei te Hydroxypropyl beta-cyclodextrin; Kāore he kakara, he reka paku; he kaha te whakaoho i te makuku. He ngāwari te wairewa o tēnei hua ki te wai, he ngāwari te wairewa ki te methanol, te ethanol, tata kore e wairewa ki te acetone, te trichloromethane.
Te wairewatanga ohydroxypropyl-B-cyclodextrinHe tino pai te whakauru ki te wai, ā, ko te taumata whakakapinga o te 4 me runga ake ka taea te whakaranu ki te wai i roto i tētahi ōwehenga, ā, ka taea hoki te rewa ki te 50% etanoru me te methanol. He āhua waikura tōna. Engari he iti noa te mahi ā-mata me te mahi hemolytic. Kāore e pāwera ki te uaua, ā, he mea tino pai hei whakarei whakarewa me te tāpiri rongoā mō te werohanga.
He aha te whakamahinga o te Hydroxypropyl beta-cyclodextrin?
I te mara o te kai me ngā mea kakara
Ka taea e te Hydroxypropyl beta-cyclodextrin te whakapai ake i te pumau me te mahi roa o ngā ngota kai, te huna, te whakatika rānei i te haunga kino me te reka o ngā ngota kai, me te whakapai ake i te tukanga whakaputa me te kounga o te hua.
I roto i ngā mea whakapaipai

He āhua hygroscopicity tōna.
I roto i te mara o te rongoā
Hydroxypropyl beta-cyclodextrinKa taea te whakapai ake i te wairewatanga wai o ngā rongoā kore-rewa, te whakanui ake i te pumau o te rongoā, te whakapai ake i te waatea o te rongoā, te whakanui ake i te whai huatanga o ngā whakaritenga rongoā, te whakaiti rānei i te horopeta, te whakatika, te whakahaere rānei i te tere tukunga o ngā rongoā, me te whakaiti i te paitini o te rongoā. Ka taea te whakamahi hei kawe i ngā rongoā ā-waha, ngā werohanga, ngā pūnaha tuku rongoā mucosal (tae atu ki te mucosa ihu, te rectum, te cornea, me ētahi atu), ngā pūnaha tuku rongoā mimiti transdermal, ngā rongoā arotahi lipophilic, ā, ka taea hoki te whakamahi hei tiaki pūmua me te whakaū.
