He aha nā māka ʻokoʻa o ka HPMC?

ʻO HPMC, a i ʻole hydroxypropyl methylcellulose, he ʻano ia o ka cellulose derivative i hoʻohana mau ʻia ma ke ʻano he mea mānoanoa, emulsifier, a me ka stabilizer i nā ʻano huahana. He pauda keʻokeʻo, ʻala ʻole, ʻono ʻole i hiki ke hoʻoheheʻe ʻia i ka wai anuanu a hiki ʻole ke hoʻoheheʻe ʻia i ka wai wela.

Loaʻa ka HPMC ma nā ʻano papa like ʻole, kēlā me kēia me kāna mau waiwai ponoʻī a me nā noi. Hoʻokumu ʻia nā māka o ka HPMC ma ke degere o ka hoʻololi ʻana (DS) o nā pūʻulu hydroxypropyl, ʻo ia ke ana o ka helu o nā pūʻulu hydroxypropyl i kēlā me kēia ʻāpana anhydroglucose. ʻO ke kiʻekiʻe o ka DS, ʻoi aku ka nui o nā hui hydroxypropyl a ʻoi aku ka hydrophilic o ka HPMC.

Hoʻokaʻawale ʻia nā māka o HPMC i ʻekolu mau ʻāpana nui: DS haʻahaʻa, DS waena, a me DS kiʻekiʻe.

Hoʻohana pinepine ʻia ka DS HPMC haʻahaʻa i nā noi kahi e makemake ʻia ai ka viscosity haʻahaʻa a me ka ikaika gel haʻahaʻa. Hoʻohana pinepine ʻia kēia papa i nā noi meaʻai a me nā mea inu, e like me ka ice cream, sauces, a me ka gravies. Hoʻohana ʻia ia i nā noi lāʻau lapaʻau, e like me nā papa a me nā capsules.

Hoʻohana ʻia ka Medium DS HPMC i nā noi kahi e makemake ʻia ai ka viscosity kiʻekiʻe a me ka ikaika gel. Hoʻohana pinepine ʻia kēia papa i nā noi meaʻai a me nā mea inu, e like me nā jams a me nā jellies, a me nā noi lāʻau lapaʻau, e like me ka ʻaila a me ka ʻaila.

Hoʻohana ʻia ʻo High DS HPMC i nā noi kahi e makemake ʻia ai ka viscosity kiʻekiʻe a me ka ikaika gel. Hoʻohana pinepine ʻia kēia papa i nā noi meaʻai a me nā mea inu, e like me ka cheese a me ka yogurt, a me nā noi lāʻau lapaʻau, e like me nā suppositories a me nā pessaries.

Ma waho aʻe o nā ʻāpana nui ʻekolu o HPMC, aia kekahi mau ʻāpana. Hoʻokumu ʻia kēia mau ʻāpana i ke ʻano o ka hoʻololi ʻana, ka nui o ka ʻāpana, a me ke ʻano o ka hui hydroxypropyl.

Hoʻokumu ʻia ka degere o nā ʻāpana hoʻololi i ka degere o ka hoʻololi ʻana o nā pūʻulu hydroxypropyl. ʻO kēia mau ʻāpana he DS haʻahaʻa (0.5-1.5), DS waena (1.5-2.5), a me DS kiʻekiʻe (2.5-3.5).

Hoʻokumu ʻia nā ʻāpana liʻiliʻi i ka nui o nā ʻāpana. Maikaʻi kēia mau ʻāpana liʻiliʻi (emi iho ma mua o 10 microns), waena (10-20 microns), a me ke koʻikoʻi (ʻoi aku ma mua o 20 microns).

Hoʻokumu ʻia ke ʻano o nā pūʻulu hydroxypropyl i ke ʻano o ka hui hydroxypropyl i loaʻa i ka HPMC. ʻO kēia mau ʻāpana he hydroxypropyl methylcellulose (HPMC), hydroxypropyl ethylcellulose (HPEC), a me ka hydroxypropyl cellulose (HPC).

ʻO ka HPMC he mea maʻalahi a hoʻohana nui ʻia i nā huahana like ʻole. Hoʻokumu ʻia nā māka like ʻole o ka HPMC ma ke kiʻekiʻe o ka hoʻololi ʻana, ka nui o nā ʻāpana, a me ke ʻano o ka pūʻulu hydroxypropyl, a loaʻa i kēlā me kēia papa kona mau waiwai ponoʻī a me nā noi.
