ʻO ka Hydroxyethyl cellulose (HEC)he polymer nonionic, wai-soluble i loaʻa mai ka cellulose kūlohelohe. Ma muli o kona palekana kiʻekiʻe a me nā waiwai paʻa, hoʻohana nui ʻia ia i ka mālama ʻili, ka hoʻomaʻemaʻe, a me nā ʻano hana makeup. ʻOi aku kona kuleana i ka mālama ʻili ma mua o ka lilo ʻana i mea mānoanoa; loaʻa iā ia nā hana he nui, me ka hoʻomaikaʻi ʻana i ka ʻili, ka hoʻopaʻa ʻana i ka ʻōnaehana, a me ke kōkua ʻana i ka hoʻokumu ʻana i ka ʻili.
1. ʻAno a me nā Waiwai
ʻO ka Hydroxyethyl cellulose kahi hua cellulose i loaʻa mai nā linters pulupulu maoli a i ʻole ka pulp lāʻau ma o nā hopena kemika e like me ka alkalization a me ka ethylene oxide etherification. ʻO nā substituents hydroxyethyl i hoʻokomo ʻia i loko o kona kaulahao molekala e hoʻonui i kona hydrophilicity, e hiki ai iā ia ke hoʻoheheʻe i loko o ka wai anuanu a me ka wai wela e hana i nā hopena colloidal moakaka a i ʻole translucent. ʻO kona ʻano nonionic e hoʻolilo iā ia i mea maʻalahi ʻole i nā hopena kemika me nā mea hoʻohui i hoʻopiʻi maikaʻi ʻole ʻia i loko o nā formulations, e hoʻolilo ana iā ia i paʻa ma waena o nā waiwai pH a me nā electrolytes.
2. Nā Hana Nui ma ka Mālama ʻIli
2.1. Ka Mana ʻana i ka Mānoanoa a me ka Viscosity
Hiki i ka HEC ke hoʻonui nui i ka mānoanoa o nā huahana mālama ʻili, e kōkua ana i ka pae wai e hana i kahi ʻano like, gel wai a i ʻole emulsion. Ke hoʻohui ʻia i nā toners, serums, a me nā masks maka, hoʻomaikaʻi ia i ka laha ʻana o ka huahana a me ka hoʻopili ʻana, e pale ana i ka wai, a e ʻae ana i ka laha like ʻana ma ka ʻili.
2.2. Ke hoʻopaʻa nei i nā ʻōnaehana Emulsion
I loko o nā ʻōnaehana ʻaila-i-ka-wai a i ʻole ka ʻaila-i-ka-wai e like me nā lotion a me nā kirīmi, hiki i ka HEC ke hoʻolohi i ka hoʻokaʻawale ʻana o ka ʻaila-wai ma ka hoʻonui ʻana i ka viscosity o ka pae wai, a laila e hoʻonui ana i ke kūpaʻa kino o ka emulsion. He mea nui loa kēia no nā formula i loaʻa nā pae kiʻekiʻe o nā mea hana a i ʻole nā aila volatile.
2.3. Hoʻomaikaʻi i ka ʻIli a me ke Kahua ʻAna o ka ʻIli
Hoʻokumu pinepine nā huahana mālama ʻili i loaʻa ka HEC i kahi ʻili pale lahilahi, moakaka, a palupalu hoʻi ma ka ʻili, e hōʻemi ana i ka mahu ʻana o ka wai a hāʻawi i kahi manaʻo siliki a ʻaʻole pipili. He mea maikaʻi loa kēia waiwai hana ʻili no nā huahana hoʻomaʻū, hōʻoluʻolu, a pale.
2.4. Hoʻokuʻu a me ka hoʻopuehu ʻana
I loko o nā huahana mālama ʻili e loaʻa ana nā ʻāpana hiki ʻole ke hoʻoheheʻe ʻia (e like me ka zinc oxide, titanium dioxide, a me ka pauka momi), hiki iā HEC ke hoʻokuʻu a hoʻopuehu like i nā ʻāpana paʻa ma ka hoʻonui ʻana i ka viscosity o ka ʻōnaehana a me ka hoʻokumu ʻana i kahi ʻano pūnaewele ʻekolu-dimensional, e pale ana i ka sedimentation a i ʻole ka clumping.
2.5. Nā mea hoʻohuihui palupalu a palekana hoʻi
ʻO HEC, i loaʻa mai ka cellulose kūlohelohe, ʻaʻole ia he mea hoʻonāukiuki a ʻaʻole hoʻi e hoʻonāukiuki, e kūlike ana me nā lula palekana hoʻonaninani honua like ʻole. ʻAʻohe ona surfactants ikaika a ʻaʻole ia e hoʻopilikia i ka pale ʻili, e hoʻohana pinepine ʻia ai i nā huahana mālama ʻili no ka ʻili koʻikoʻi a i ʻole nā pēpē.
3. Nā Laʻana Hoʻohana ma nā Huahana Mālama ʻIli like ʻole
Nā Serum Hoʻomaʻū: ʻO nā haʻahaʻa haʻahaʻa o HEC (0.2%-0.5%) e hoʻonui i ka wai a hoʻomaikaʻi i ka hoʻopili ʻana, ʻoiai e hoʻopaʻa ana i ka hoʻolaha ʻana o nā humectants e like me ka hyaluronic acid a me ka glycerin i loko o ka ʻōnaehana.
Kirimi a me nā Lotions: ʻO ka nui o ka mahele ma lalo o 1% hiki ke hoʻomaikaʻi nui i ke kūpaʻa o ka ʻōnaehana emulsion, e hopena ana i kahi kāpili laumania a palupalu.
Nā Pale Maka a me nā Gels: Hāʻawi ʻo HEC i kahi ʻano moakaka, e like me ka gel a kōkua i ka hoʻokuʻu like ʻana i nā mea hana. Pale Lā: Hana ma ke ʻano he mea hoʻomaha a me ke kōkua hana kiʻiʻoniʻoni, e kōkua ana i ka hoʻopuehu like ʻana i nā pauka pale lā a hoʻoikaika i ke kūlike a me ke kūpaʻa wai o ka ʻili pale.
4. Nā Pōmaikaʻi Noi
Hoʻohālikelike maikaʻi loa: Kūlike me ka hapa nui o nā mea hana mālama ʻili, nā moisturizers, nā mea mālama, a me nā mea hou aku.
Paʻa Ikaika: Paʻa i loko o ka pae pH o 3-11 a ʻaʻole i hoʻopilikia ʻia e ka hapa nui o nā electrolytes.
Palekana a Pilikino i ke Kaiapuni: Biodegradable, e like me nā loina hoʻohui ʻōmaʻomaʻo.
Ka Hana Maʻalahi: Hoʻoheheʻe anu a hoʻoheheʻe wela hoʻi, kūpono no nā ʻano hana like ʻole.
Ka waiwai o HEC i ka mālama ʻiliʻaʻole wale ia ma kona pono ma ke ʻano he mea hoʻomānoanoa maikaʻi loa a palupalu hoʻi, akā ma kona hiki ke hoʻomaikaʻi i ke ʻano holoʻokoʻa o ka huahana, hoʻolōʻihi i ke ola papa, a hoʻonui i ka ʻike ʻili o ka mea hoʻohana. Inā paha ma ka mālama ʻili i kēlā me kēia lā, ka mālama ʻili hana, nā mea hoʻonaninani kala, a i ʻole ka sunscreen, lawelawe ʻo HEC ma ke ʻano he mea nui i nā ʻano paʻa a palekana, e hāʻawi ana i ke kākoʻo paʻa no ka hana hope loa o ka huahana.
