Hypromellose 2208 a me 2910

ʻO ka Hypromellose, ka mea i kapa ʻia ʻo hydroxypropyl methylcellulose (HPMC), he ether non-toxic a non-ionic cellulose e hoʻohana ʻia i nā ʻano noi like ʻole, me nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā huahana meaʻai. Loaʻa ka HPMC ma nā papa he nui, me Hypromellose 2208 a me 2910, nona nā waiwai a me nā noi like ʻole.

ʻO ka Hypromellose 2208 kahi papa viscosity haʻahaʻa o HPMC i hoʻohana mau ʻia ma ke ʻano he mea hoʻopaʻa, mānoanoa, a me ke kiʻiʻoniʻoni mua i nā lāʻau lapaʻau. Hoʻohana pinepine ʻia ia i loko o nā uhi papa, kahi e hāʻawi ai i kahi ʻili laulima, ʻālohilohi a hoʻomaikaʻi i ka paʻa o ka papa. Hoʻohana pū ʻia ʻo Hypromellose 2208 i nā ʻano ophthalmic, kahi e hana ai ʻo ia me kahi lubricant a hoʻomaikaʻi i ka viscosity o ka formulation.

ʻO Hypromellose 2910 kahi papa viscosity kiʻekiʻe o ka HPMC i hoʻohana ʻia ma ke ʻano he mānoanoa, hoʻopaʻa, a me ka emulsifier i nā ʻano o nā noi. I loko o nā lāʻau lapaʻau, hoʻohana pinepine ʻia ia ma ke ʻano he mea hoʻokuʻu paʻa, no ka mea e hoʻokuʻu mālie ʻo ia i ka mea hana i ka manawa. Hoʻohana ʻia ʻo Hypromellose 2910 i nā mea hoʻonaninani, kahi e hāʻawi ai i kahi hopena mānoanoa, hoʻomaikaʻi i ka paʻa o nā emulsions, a hoʻonui i ke ʻano o ka huahana.

I ka hōʻuluʻulu ʻana, ʻo Hypromellose 2208 a me 2910 ʻelua mau māka o HPMC me nā waiwai a me nā noi like ʻole. ʻO Hypromellose 2208 kahi papa viscosity haʻahaʻa i hoʻohana ʻia i nā lāʻau lapaʻau, ʻoiai ʻo Hypromellose 2910 kahi papa viscosity kiʻekiʻe i hoʻohana ʻia i nā lāʻau lapaʻau, nā mea hoʻonaninani, a me nā noi ʻē aʻe.
