Povidone-K90 / PVP-K90 kūʻai nui

| INCI | Molekala |
| POVIDONE-K90 | ( C6H9NO )n |
Hoʻohana ʻia ʻo Povidone (polyvinylpyrrolidone, PVP) i ka ʻoihana lāʻau lapaʻau ma ke ʻano he kaʻa polymer synthetic no ka hoʻopuehu ʻana a me ke kāpae ʻana i nā lāʻau. He nui kona mau hoʻohana, me ke ʻano he mea hoʻopaʻa no nā papa a me nā capsules, kahi mea hana kiʻiʻoniʻoni no nā hopena ophthalmic, e kōkua i ka hoʻāla ʻana i nā wai a me nā papa nau, a ma ke ʻano he mea hoʻopili no nā ʻōnaehana transdermal.
ʻO ke ʻano molekala o Povidone ʻo (C6H9NO)n a ʻike ʻia he pauka keʻokeʻo a keʻokeʻo iki paha. Hoʻohana nui ʻia nā ʻano Povidone i ka ʻoihana lāʻau lapaʻau ma muli o ko lākou hiki ke hoʻoheheʻe i loko o nā mea hoʻoheheʻe wai a me ka ʻaila. ʻO ka helu k e pili ana i ke kaumaha molekala awelika o ka povidone. ʻAʻole hāʻawi pinepine ʻia nā Povidones me nā waiwai K kiʻekiʻe (ʻo ia hoʻi, k90) ma o ka inikini ma muli o ko lākou kaumaha molekala kiʻekiʻe. ʻO nā kaumaha molekala kiʻekiʻe e pale aku i ka hoʻokuʻu ʻia e nā puʻupaʻa a alakaʻi i ka hōʻiliʻili ʻana i loko o ke kino. ʻO ka laʻana kaulana loa o nā ʻano povidone ʻo ia ka povidone-iodine, kahi mea hoʻomaʻemaʻe koʻikoʻi.
Pauka keʻokeʻo e kahe manuahi ana, kūpaʻa maikaʻi, ʻaʻole hoʻonāukiuki, hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethnol, palekanaa maʻalahi hoʻi e hoʻohana,. Kūpono i ka pepehi ʻana i nā bacillus, nā virus a me nā epiphytes. Kūlike me ka hapa nui o ka ʻili.
Loaʻa ma ke ʻano he pauka ʻulaʻula ʻeleʻele e kahe manuahi ana, ʻaʻole hoʻonāukiuki me ke kūpaʻa maikaʻi, hoʻoheheʻe i ka wai a me ka waiʻona, ʻaʻole hoʻoheheʻe ʻia i ka diethylene a me ka chloroform.

ʻO ka Polyvinylpyrrolidone ma ke ʻano he pauka a i ʻole ka hopena. Loaʻa ka PVP i nā mousse hoʻonaninani, ka eruption, a me ka lauoho, ka pena, ka ʻīnika paʻi, ka lole, ka paʻi ʻana a me ka hoʻoluʻu ʻana, hiki ke hoʻohana ʻia nā paipu kiʻi kala e like me nā mea uhi ʻili, nā mea hoʻopuehu, nā mea mānoanoa, nā mea hoʻopaʻa. I ka lāʻau lapaʻau, hoʻohana nui ʻia nā mea hoʻopaʻa no nā papa, nā granules a pēlā aku.
