ʻO ka Hydroxyethylcellulose (HEC) he polymer wai-soluble maʻamau i hoʻohana nui ʻia i nā mea hoʻonaninani a me nā huahana mālama pilikino. Hoʻohana maʻamau ia ma ke ʻano he mānoanoa, stabilizer a me ke kiʻiʻoniʻoni mua i nā huahana mālama ʻili like ʻole, shampoos, ʻauʻau wai, lotions, gels a me nā huahana ʻē aʻe. Ua loaʻa ka manaʻo nui o kona palekana i ke kahua hoʻonaninani.
Nā waiwai kemika a me ka hana o ka hana
Hana ʻia ka Hydroxyethylcellulose e ka mālama ʻana i ka cellulose me ka sodium hydroxide a me ka hoʻopili ʻana me ka ethylene oxide. ʻO ka cellulose kahi polysaccharide i loaʻa maoli i nā mea kanu, a ma o kēia kaʻina hana, ua hoʻonui ʻia ka hoʻoheheʻe wai o cellulose, i kūpono ia no ka hoʻohana ʻana i nā ʻano wai. He hopena mānoanoa maikaʻi ka Hydroxyethylcellulose, hiki ke hoʻonui i ka viscosity o ka huahana, e hoʻomaʻamaʻa i ka huahana a maʻalahi hoʻi i ka hoʻohana ʻana. Eia kekahi, he kiʻiʻoniʻoni hoʻi ʻo HEC a hiki ke hana i kahi kiʻiʻoniʻoni pale ma ka ʻili o ka ʻili a i ʻole ka lauoho e pale ai i ka hoʻoheheʻe ʻana o ka wai a pāʻani i kahi hana moisturizing.
Palekana o Hydroxyethyl Cellulose
Ua loiloi ʻia ka palekana o ka hydroxyethyl cellulose e nā hui mana. Wahi a ka loiloi o ka Cosmetic Ingredient Review Committee (CIR) ma United States a me ka European Cosmetic Regulation (EC No 1223/2009), ua manaʻo ʻia ʻo Hydroxyethylcellulose he mea hoʻonaninani palekana. Ma loko o ka laulā o ka hoʻohana ʻana, ʻaʻole e hoʻopilikia ka HEC i ke olakino kanaka.
Nā haʻawina toxicological: Ua hōʻike ʻia kekahi mau noiʻi toxicological ʻaʻole hiki i ka Hydroxyethylcellulose ke hoʻoulu i ka ʻili a i ʻole ka hopena maʻi. ʻAʻole i loaʻa i nā hoʻāʻo ʻawaʻawa a me nā hoʻāʻo ʻawaʻawa lōʻihi i ka HEC he carcinogenic, mutagenic a i ʻole nā mea ʻawaʻawa hānau. No laila, manaʻo nui ʻia ʻo ia he mea ʻoluʻolu a maikaʻi ʻole no ka ʻili a me nā maka.
ʻO ka ʻili o ka ʻili: Ma muli o kona paona molekala nui, ʻaʻole hiki i ka Hydroxyethylcellulose ke hele i loko o ka pale ʻili a komo i ke kaʻe ʻana o ke kino. ʻOiaʻiʻo, hana ʻo HEC i kahi kiʻiʻoniʻoni pale ma hope o ka hoʻohana ʻana, e waiho ana ma ka ʻili o ka ʻili me ke komo ʻole i loko o ka ʻili. No laila, ʻaʻole ia e hana i nā hopena systemic i ke kino o ke kanaka, kahi e hoʻomaikaʻi hou ai i kona palekana.
Ka palekana o ke kaiapuni: Hiki ke hoʻoheheʻe ʻia ka Hydroxyethylcellulose i loko o ke kaiapuni a ʻaʻole ia e hoʻohaumia i ka kaiaola no ka wā lōʻihi. Ua ʻike ʻia kona palekana kaiapuni e nā hui mālama kaiapuni.
Ka noi a me ka loiloi palekana i ka cosmetic
ʻO ka nui o ka hydroxyethyl cellulose i loko o nā mea hoʻonaninani he haʻahaʻa loa, ma waena o 0.1% a me 2%. Aia ma lalo o ka paepae palekana i ʻike ʻia, no laila palekana loa ka hoʻohana ʻana i kēia mau ʻike. Ma muli o kona kūpaʻa a me ka hoʻohālikelike maikaʻi, hoʻohana nui ʻia ʻo HEC i nā mea hoʻonaninani like ʻole e hoʻomaikaʻi i ke ʻano a me ka ʻike mea hoʻohana o ka huahana.
ʻO ka Hydroxyethyl cellulose kahi mea hoʻohana nui a palekana loa i nā mea hoʻonaninani. Inā ma ka hoʻohana pōkole a i ʻole ka pilina lōʻihi, ʻaʻole hōʻike ʻo HEC i kahi pōʻino i ke olakino kanaka. Ma ka manawa like, hoʻolilo ʻo ia i mea hoʻonaninani kaulana i kēia lā no ka ulu ʻana o ka hoʻomohala hoʻomau a me ka ʻike kaiapuni. ʻAʻole pono nā mea kūʻai aku e hopohopo e pili ana i kona palekana i ka wā e hoʻohana ai i nā huahana i loaʻa ka hydroxyethyl cellulose, a hiki ke hauʻoli i ka ʻike hoʻohana maikaʻi loa a me nā hopena e lawe mai ai.
