ʻO ka HPMC (hydroxypropyl methylcellulose) he mea koʻikoʻi i loaʻa maoli i ka cellulose derivative i hoʻohana nui ʻia i nā mea hoʻonaninani a me nā huahana mālama pilikino. Ma muli o kāna mau waiwai kino a me nā kemika, he nui nā noi i ka mālama ʻili, mālama lauoho a me nā huahana makeup.
Nā waiwai kumu o HPMC
ʻO ka HPMC he polymer hiki ke hoʻoheheʻe ʻia i ka wai i hoʻololi ʻia mai ka cellulose. Loaʻa i kāna ʻano molekala nā pūʻulu hydrophilic hydroxyl a me ka hydrophobic methyl a me nā pūʻulu propyl, hāʻawi iā ia i ka solubility maikaʻi a me ka hiki ke mānoanoa i ka wai. ʻO nā hiʻohiʻona o ka HPMC e hilinaʻi nui ʻia i kona degere o ka hoʻololi ʻana (ka ratio o ka hydroxypropyl i ka methyl) a me ke kaumaha mole. Hoʻopili pololei kēia mau mea i kāna hana ma nā ʻano hana like ʻole.
ʻO ke kuleana o HPMC i nā mea hoʻonaninani
Mea mānoanoa: Hiki i ka HPMC ke hana i kahi ʻoluʻolu viscous akaka i loko o ka wai, no laila hoʻohana pinepine ʻia e like me ka mānoanoa i nā mea hoʻonaninani. He maʻalahi kona hopena mānoanoa a hiki ke hoʻonui nui i ka viscosity huahana ma nā haʻahaʻa haʻahaʻa. Ke hoʻohālikelike ʻia me nā mānoanoa maʻamau e like me ka carbomer, ʻo ka maikaʻi o ka HPMC ʻo ia ka liʻiliʻi o ka hoʻonāukiuki ʻana i ka ʻili a hiki ke hana i kahi ʻano maʻemaʻe, siliki.
Emulsion stabilizer: Ma ka emulsion a me ka hoʻopili ʻana i nā huahana, hiki ke hoʻohana ʻia ka HPMC ma ke ʻano he emulsion stabilizer e kōkua i ka pae ʻaila a me ka pae wai e hoʻohui maikaʻi a pale i ka hoʻokaʻawale ʻana o ka ʻaila a me ka wai. He mea koʻikoʻi kēia waiwai i nā huahana creamy e like me nā sunscreens a me nā ʻili ʻili. Mālama ʻo HPMC i ka paʻa o ka huahana ma o ka hoʻokumu ʻana i kahi ʻano micelle paʻa e hoʻopili ai i nā kulu ʻaila a hoʻopuehu like i ka wai.
Mea hana kiʻiʻoniʻoni: Loaʻa i ka HPMC nā waiwai hana kiʻiʻoniʻoni a hiki ke hana i kahi kiʻiʻoniʻoni pale palupalu a hanu i ka ʻili. Hoʻohana ʻia kēia hiʻohiʻona i nā huahana make-up, e like me ke kumu wai a me ka pale maka, e hoʻomaikaʻi i ka lōʻihi o ka huahana a pale i ka hāʻule ʻana a i ʻole ka smudging. Eia kekahi, hiki i nā mea hana kiʻiʻoniʻoni o HPMC ke hoʻomaikaʻi i ka hopena moisturizing o nā huahana mālama ʻili a kōkua i ka laka i ka makū.
Lubricant a paheʻe: Hiki i ka HPMC ke hoʻomaikaʻi i ka lubricity o nā formula i loko o nā mea hoʻonaninani, e maʻalahi ai ka hoʻopili ʻana a puʻunaue like i ka huahana ma ka ʻili a i ʻole ka lauoho. No ka laʻana, i nā conditioners, hiki i ka HPMC ke hoʻonui i ka silkiness, e hoʻomaʻamaʻa i ka lauoho a maʻalahi hoʻi i ka hui. Loaʻa kēia hopena lubrication mai ka hopena viscous i hana ʻia e HPMC i hoʻoheheʻe ʻia i ka wai, hiki ke hana i kahi kiʻiʻoniʻoni pale ma ka ʻili a i ʻole ka lauoho lauoho, a laila e hōʻemi ai i ka friction.
Hoʻonui i ke ʻano o nā mea hoʻonaninani
ʻO Texture kekahi o nā hiʻohiʻona koʻikoʻi o nā mea hoʻonaninani, e pili pono ana i ka ʻike o nā mea kūʻai. Ma ke ʻano he mānoanoa maʻamau a me ka hoʻololi rheology, hiki i ka HPMC ke hoʻomaikaʻi nui i ke ʻano o nā mea hoʻonaninani, ʻokoʻa i nā ʻano aʻe:
Manaʻo maʻalahi: ʻO ka wai colloidal i hana ʻia ma hope o ka hoʻoheheʻe ʻia ʻana o HPMC he paʻi maʻalahi, hiki iā ia ke hāʻawi i nā lotions a me nā ʻaila i kahi ʻano maʻalahi. Ke hui pū ʻia me nā mea ʻē aʻe e like me ka aila a me ka waxes, hiki iā ia ke hōʻemi i ka graininess o ka huahana, hoʻonui i ka kūlike o ke ʻano a me ka maʻalahi o ka noi.
ʻoluʻolu: I ka mālama ʻana i ka ʻili, kōkua kahi ʻano palupalu i nā huahana e komo a komo maikaʻi. ʻO ka kiʻiʻoniʻoni i hana ʻia e HPMC he maʻalahi a me ka elasticity maikaʻi, hiki ke kōkua i nā huahana e puʻunaue like ma ka ʻili o ka ʻili me ka mālama ʻana i ka palupalu haʻahaʻa e pale aku ai i nā huahana paʻa a maloʻo paha.
Scalability: Ma nā mea hoʻonaninani, hoʻomaikaʻi ʻo HPMC i ka ductility o ka huahana ma o ka hoʻoponopono ʻana i ka wai o ke ʻano. ʻOi aku i nā huahana make-up, e like me ke kumu, lipstick, a me nā mea ʻē aʻe, hiki i ka HPMC ke kōkua i ka huahana e pili pono i ka ʻili a pale i ka pipili ʻana a i ʻole ka like ʻole.
E hoʻomaikaʻi i ka rheology
ʻO ka Rheology e pili ana i nā waiwai o nā mea e kahe ana a me ka deform ma lalo o ka mana o nā mana o waho. I nā mea hoʻonaninani, pili pono ka rheology i ka pālahalaha ʻana, kūpaʻa a me ke ʻano o ka huahana. Ma ke ʻano he rheology modifier, hiki i ka HPMC ke hoʻomaikaʻi nui i nā waiwai rheological o nā mea hoʻonaninani, e ʻoi aku ka ʻoluʻolu a me ka maʻalahi o ka hana i ka wā hoʻohana.
ʻAhi ʻāhi: Hōʻike ka HPMC i kekahi mau hiʻohiʻona wai ʻaʻole Newtonian, ʻoi aku ka nui o nā waiwai ʻāhiʻi ma nā ʻano kiʻekiʻe. ʻO ia ke ʻano o ka hoʻohana ʻana i ka ikaika o waho (e laʻa, ka hoʻolaha ʻana, ka hoʻoulu ʻana), e emi ana ka viscosity o ka hopena, e maʻalahi ai ka laha ʻana a me ka puʻunaue. I ka pau ʻana o ka noi, e hoʻi mālie ka viscosity, e hōʻoia ana ʻaʻole e holo a kulu ka huahana.
Thixotropy: Loaʻa i ka HPMC ka thixotropy, ʻo ia ka mea e hōʻike ana i ka viscosity kiʻekiʻe i kahi kūlana paʻa e pale aku i ka holo ʻana o ka huahana, akā i ka wā e ʻike ʻia ai i ka ikaika o waho, e emi ana ka viscosity, e maʻalahi ka hoʻohana. ʻO kēia hiʻohiʻona he mea kūpono loa ka HPMC no ka hoʻohana ʻana i ka pale lā, ke kumu a me nā huahana ʻē aʻe e pono ai kahi papa kiʻiʻoniʻoni ma ka ʻili.
Paʻa huahana: ʻAʻole hoʻomaikaʻi wale ʻo HPMC i ke ʻano o ka huahana, akā hoʻomaikaʻi pū i kona kūpaʻa. I nā emulsions a i ʻole ka hoʻokuʻu ʻana, hiki i ka HPMC ke hōʻemi i nā hanana paʻa ʻole e like me ka stratification ʻaila-wai a me ka hoʻonohonoho ʻana o nā mea, a hoʻolōʻihi i ke ola o nā huahana ma o ka mānoanoa a me ka hoʻonui ʻana i ka ʻōnaehana pūnaewele.
Ma ke ʻano he kumu waiwai, hāʻawi ʻo HPMC i nā mea hoʻomohala formulation me kahi ākea o nā hiki ke noi ma o ka hoʻomaikaʻi ʻana i ke ʻano a me ka rheology o nā mea hoʻonaninani. ʻAʻole ia e hoʻomaikaʻi wale i ka hiʻohiʻona a me ka hoʻohana ʻana i nā mea hoʻonaninani, akā he mau hana like ʻole e like me ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, lubrication, a me ka stabilization, e ʻoi aku ka ʻoluʻolu o ka huahana, lōʻihi, a palekana. Ke piʻi aʻe nei nā koi o ka ʻoihana hoʻomaʻemaʻe no ke ʻano a me ka rheology, e ʻoi aku ka laulā o nā manaʻo noi HPMC.
