(HPMC) He aha ka ʻokoʻa me S a ʻole paha?

Me he mea lā ke ʻōlelo nei ʻoeHydroxypropyl Methylcellulose (HPMC), he polymer i hoʻohana nui ʻia i nā ʻoihana like ʻole me ka lāʻau lapaʻau, ke kūkulu ʻana, ka meaʻai, a me nā mea hoʻonaninani. ʻO ka ʻokoʻa ma waena o ka HPMC me ka huaʻōlelo 'S' a me ka ʻole o ka leka 'S' pili paha i nā māka like ʻole, nā ʻano hana, a i ʻole nā ​​huahana kikoʻī.

ʻO Hydroxypropyl Methylcellulose (HPMC) he semi-synthetic, inert, viscoelastic polymer i loaʻa mai ka cellulose. Hana ʻia ia ma o ka hoʻololi kemika o cellulose, e pili ana i ka mālama ʻana i ka cellulose me ka alkali a me ka propylene oxide e hoʻolauna i nā hui hydroxypropyl a me methyl.

Eia kekahi mau mea nui e pili ana i ka HPMC:

Hoʻolālā Kemika: Aia ka HPMC i nā kaulahao lōʻihi o nā ʻāpana glucose me nā pūʻulu hydroxypropyl a me methyl i hoʻopili ʻia i kekahi o nā hui hydroxyl (-OH). Hiki ke ʻokoʻa ka ratio o kēia mau mea pani, e alakaʻi ana i nā māka like ʻole o ka HPMC me nā waiwai ʻokoʻa.

Nā Pono Kino: Hiki ke hoʻoheheʻe ʻia ka HPMC i loko o ka wai a hoʻoheheʻe ʻia i loko o ka wai. Hiki ke hoʻomalu ʻia kona viscosity e ka hoʻoponopono ʻana i nā ʻāpana e like me ke kaumaha molecular, degere o ka hoʻololi ʻana, a me ka ʻike.

Nā noi:

Lapaʻau Lapaʻau: Hoʻohana maʻamau ʻia ka HPMC i loko o nā ʻano lāʻau lapaʻau ma ke ʻano he mānoanoa, mea hoʻopili, kiʻiʻoniʻoni mua, a me ka mea hoʻokuʻu hoʻomau mau i nā papa, capsules, a me nā ʻano kumuhana.
Hana ʻia: Ma nā mea hana e like me nā morta, renders, a me nā mea hoʻopili tile, hoʻomaikaʻi ʻo HPMC i ka hana, paʻa wai, a me ka hoʻopili.
Meaʻai: Hoʻohana ʻia ʻo HPMC i nā huahana meaʻai e like me ka mānoanoa, stabilizer, a me ka emulsifier. Loaʻa pinepine ia i loko o nā huahana waiu, nā mea ʻai, a me nā mea ʻono.
Mea Hoʻomaʻamaʻa: Hoʻokomo ʻia ʻo HPMC i loko o nā mea hoʻonaninani a me nā huahana mālama pilikino e like me ka cream, lotions, a me nā shampoos e hoʻomaikaʻi ai i ke ʻano, kūpaʻa, a me nā waiwai hana kiʻiʻoniʻoni.

Nā pōmaikaʻi:

Hāʻawi ʻo HPMC i nā waiwai paʻa wai maikaʻi loa, he mea koʻikoʻi ia no nā noi e like me nā mortar ciment-based kahi e pono ai ka hydration lōʻihi no ka hoʻōla kūpono.
Hoʻonui ia i ka adhesion a me ka hana i nā mea hana, e hāʻawi ana i ka hana maikaʻi a me ka lōʻihi.
I loko o nā lāʻau lapaʻau, hoʻomaʻamaʻa ʻo HPMC i ka hoʻokuʻu ʻana i ka lāʻau lapaʻau a hoʻonui i nā waiwai disintegration papa.
Manaʻo ʻia ʻo HPMC he palekana no ka ʻai ʻana a ua ʻae nui ʻia i nā meaʻai a me nā huahana hoʻonaninani.
Nā māka a me nā kikoʻī: Loaʻa ka HPMC i nā māka like ʻole a me nā kikoʻī i hoʻohālikelike ʻia i nā noi kikoʻī. Hoʻopili kēia i nā ʻokoʻa o ka viscosity, ka nui o ka ʻāpana, ka pae hoʻololi, a me nā ʻāpana ʻē aʻe e hoʻokō i nā koi o nā ʻoihana like ʻole a me nā ʻano hana.

Kūlana Hoʻoponopono: ʻIke ʻia ʻo HPMC he palekana (GRAS) e nā luna hoʻoponopono e like me ka US Food and Drug Administration (FDA) ke hoʻohana ʻia e like me nā hana hana maikaʻi.

ʻO HPMC kahi polymer versatile me nā noi like ʻole ma nā ʻoihana. Hiki ke hoʻopili ʻia kona mau waiwai e hoʻokō i nā koi kikoʻī, e lilo ia i mea waiwai nui i nā ʻano hana like ʻole a me nā huahana. Inā loaʻa iā ʻoe ka ʻike kikoʻī hou aʻe e pili ana i ka HPMC me ka leka 'S' a i ʻole, e ʻoluʻolu e hāʻawi i ka pōʻaiapili hou aʻe no ka wehewehe kikoʻī hou aku.
