He aha ka hydroxypropyl methyl cellulose?

Hydroxypropyl methylcellulose(HPMC) he polymer synthetic i hoʻohana nui ʻia i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā meaʻai, nā mea hoʻonaninani, a me ke kūkulu ʻana. He ʻano ia o ka cellulose ether i hana ʻia e ka hoʻololi kemika o ka cellulose maoli, ʻo ia hoʻi kahi kaʻapona paʻakikī i loaʻa i nā mea kanu. ʻO ka HPMC he mea hiki ke hoʻoheheʻe ʻia i ka wai, ʻaʻala ʻole, a me ka ʻono ʻole i loaʻa nā waiwai he nui e hoʻohana pono ai i nā ʻano hana.

Hoʻokumu ʻia ka HPMC i ʻelua mau mea nui: methyl cellulose (MC) a me hydroxypropyl cellulose (HPC). ʻO ka MC he mea hoʻoheheʻe cellulose i loaʻa ma ka hana ʻana i ka cellulose me ka sodium hydroxide a me ka methyl chloride. ʻO kēia kaʻina hana i ka hoʻohui ʻana i nā pūʻulu methyl i ka iwi kuamoʻo cellulose, kahi e hoʻomaikaʻi ai i kona hoʻoheheʻe ʻana i ka wai. ʻO ka HPC, ma ka ʻaoʻao ʻē aʻe, he mea ia o ka cellulose i loaʻa ma ka hana ʻana me ka propylene oxide. ʻO kēia kaʻina hana i ka hoʻohui ʻana o nā pūʻulu hydroxypropyl i ka iwi kuamoʻo cellulose, kahi e hoʻomaikaʻi hou ai i kona solubility i ka wai.

ʻO ka hui pū ʻana o kēia mau mea ʻelua i loko o ka HPMC e hāʻawi iā ia me nā waiwai kūʻokoʻa e like me ka hoʻonui ʻana i ka viscosity, hoʻomaikaʻi i ka mālama ʻana i ka wai, a me ka hoʻopili ʻana. Loaʻa iā ia ka hiki ke hana i nā gels ke hui pū ʻia me ka wai, e lilo ia i mea pono ma ke ʻano he mānoanoa ma nā ʻoihana he nui.

ʻO nā noi lāʻau lapaʻau o HPMC

ʻO kekahi o ka hoʻohana mua ʻana o HPMC aia i ka ʻoihana lāʻau lapaʻau, kahi i hoʻohana ʻia ai ma ke ʻano he excipient i ka hoʻokumu ʻana i nā huahana lāʻau like ʻole. ʻO ka excipient kahi mea i hoʻohui ʻia i kahi huahana lāʻau e hoʻomaʻamaʻa i kāna hana ʻana, hoʻokele, a i ʻole ka lawe ʻana. Hoʻohana pinepine ʻia ʻo HPMC ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka mānoanoa i ka hoʻokumu ʻana i nā papa, nā capsules, a me nā ʻano mea paʻa ʻē aʻe.

I loko o nā papa papa, hoʻohana ʻia ka HPMC ma ke ʻano he mea hoʻopaʻa e hoʻopaʻa pū i ka mea hana a me nā mea hoʻohui ʻē aʻe. Hoʻohana ʻia ʻo ia ma ke ʻano he disintegrant, e kōkua ana i ka papa e wāwahi i ka wā e pili ai me ka wai a i ʻole nā ​​​​waiwai kino ʻē aʻe. He mea pono loa ka HPMC ma ke ano he disintegrant i na papa i manaoia e ale holookoa, no ka mea e hiki ai i ka papa ke wawahi koke a hookuu i ka mea hana.

Hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa ma nā ʻano wai e like me ka hoʻokuʻu ʻana, emulsions, a me nā gels. Hoʻomaikaʻi ia i ka viscosity a me ke ʻano o kēia mau ʻano, hiki ke hoʻomaikaʻi i ko lākou kūpaʻa a me ka maʻalahi o ka hoʻokele. Eia hou, hiki ke hoʻohana ʻia ka HPMC ma ke ʻano he mea hoʻokuʻu hoʻomau, kahi e hiki ai ke hoʻokuʻu mālie ʻia ka lāʻau i kahi manawa lōʻihi.

Nā noi meaʻai o HPMC

I ka ʻoihana meaʻai, hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa, emulsifier, a me ka stabilizer. Hoʻohana maʻamau ia i nā meaʻai, nā lole, a me nā huahana meaʻai wai e hoʻomaikaʻi i ko lākou ʻano a me ke kūpaʻa. Hiki ke hoʻohana ʻia ka HPMC ma ke ʻano he momona momona i nā huahana meaʻai haʻahaʻa momona, no ka mea hiki iā ia ke hoʻohālike i ke ʻano a me ka waha o ka momona me ka ʻole o ka hoʻohui ʻana i nā calorie.

Nā mea hoʻonani o HPMC

Hoʻohana pū ʻia ʻo HPMC i ka ʻoihana hoʻonaninani ma ke ʻano he mānoanoa, emulsifier, a me ka binder. Hoʻohana maʻamau ia i loko o nā lotions, creams, a me nā mea hoʻonaninani ʻē aʻe e hoʻomaikaʻi i ko lākou ʻano a me ke kūpaʻa. Hiki ke hoʻohana ʻia ʻo HPMC ma ke ʻano he mea hana kiʻiʻoniʻoni, hiki ke hoʻomaikaʻi i ka adhesion a me ka pale wai o nā huahana cosmetic.

Nā noi kūkulu hale o HPMC

I ka ʻoihana kūkulu, hoʻohana ʻia ʻo HPMC ma ke ʻano he mea mānoanoa a me ka mea paʻa wai i loko o nā hana sima a me ka mortar. Hiki iā ia ke hoʻomaikaʻi i ka hana a me ka paʻa ʻana o kēia mau formulations, hiki ke hoʻomaikaʻi i kā lākou hana a me ka lōʻihi. Hiki ke hoʻohana ʻia ka HPMC ma ke ʻano he colloid pale, hiki ke pale i ka hui ʻana o nā ʻāpana sima a hoʻomaikaʻi i ko lākou dispersibility.

Palekana a Hooponopono

Manaʻo ʻia ʻo HPMC he palekana no ka hoʻohana ʻana i nā meaʻai, lāʻau lapaʻau, a me nā huahana hoʻonaninani. Ua aʻo nui ʻia no kona palekana a me ka ʻawaʻawa, a ua helu ʻia ma ke ʻano he mea ʻawaʻawa, non-carcinogenic, a me ka non-mutagenic.

Ma ʻAmelika Hui Pū ʻIa, hoʻoponopono ʻia ʻo HPMC e ka Food and Drug Administration (FDA) ma ke ʻano he meaʻai meaʻai, a e ka United States Pharmacopeia (USP) ma ke ʻano he lāʻau lapaʻau. Hoʻoponopono ʻia e nā ʻoihana hoʻoponopono ʻē aʻe ma nā ʻāina like ʻole a puni ka honua.

ʻOiai ka palekana, hiki i ka HPMC ke hoʻoulu i nā hōʻailona maʻi o ka ʻōpū e like me ka pehu ʻana, ka ʻūhā, a me ka maʻi maʻi i kekahi poʻe. ʻO kēia mau hōʻailona maʻamau ka maʻalahi a me ka pale ʻana iā ia iho, a hiki ke pale ʻia ma ka ʻai ʻana i ka HPMC me ka haʻahaʻa.

I ka hopena, ʻo ka hydroxypropyl methylcellulose (HPMC) he polymer synthetic versatile a hoʻohana nui ʻia i loaʻa nā noi he nui i nā ʻoihana like ʻole. ʻO kāna mau waiwai kūʻokoʻa, e like me ka hoʻonui ʻana i ka viscosity, hoʻomaikaʻi i ka paʻa ʻana o ka wai, a me ka hoʻopili ʻana i hoʻonui ʻia, e lilo ia i mea pono e like me kahi mea mānoanoa, emulsifier, stabilizer, a me nā mea hoʻopaʻa i nā lāʻau lapaʻau, nā meaʻai, nā mea hoʻonaninani, a me nā huahana kūkulu. Manaʻo ʻia ʻo HPMC he palekana a hoʻoponopono ʻia e nā ʻoihana hoʻoponopono like ʻole a puni ka honua.
