He aha ka dioxane?No hea mai ia?
ʻO Dioxane, ʻo ke ala pololei e kākau ai ʻo ia ka dioxane.No ka paʻakikī loa o ka ʻino ke paʻi ʻana, ma kēia ʻatikala mākou e hoʻohana ai i nā ʻōlelo ʻino maʻamau.He pūhui mea ola, i ʻike ʻia ʻo dioxane, 1, 4-dioxane, wai kala ʻole.ʻO ka lāʻau ʻawaʻawa ʻo Dioxane he mea ʻawaʻawa haʻahaʻa, loaʻa nā hopena anesthetic a hoʻoulu.Wahi a ka Code Safety Technical Code of Cosmetics i Kina, ʻo dioxane kahi mea pāpā ʻia o nā mea hoʻonaninani.No ka mea ua papa ʻia ka hoʻohui ʻana, no ke aha i loaʻa ai ka ʻike dioxane i nā mea hoʻonaninani?No nā kumu i hiki ʻole ke pale ʻia, hiki ke hoʻokomo ʻia ka dioxane i loko o nā mea hoʻonaninani ma ke ʻano he haumia.No laila he aha nā mea haumia i loko o nā mea maka?
ʻO kekahi o nā mea hoʻomaʻemaʻe i hoʻohana nui ʻia i nā shampoos a me nā holoi kino ʻo ia ka sodium fatty alcohol ether sulfate, ʻike ʻia hoʻi ʻo ka sodium AES a i ʻole SLES.Hiki ke hana ʻia kēia ʻāpana mai ka aila pāma maoli a i ʻole ka ʻaila ma ke ʻano he mea maka i loko o nā ʻawaʻawa momona, akā hoʻohui ʻia ma o ke ʻano o nā ʻanuʻu e like me ka ethoxylation, sulfonation, a me ka neutralization.ʻO ka ʻanuʻu koʻikoʻi ʻo ka ethoxylation, ma kēia ʻanuʻu o ke kaʻina hana, pono ʻoe e hoʻohana i kahi mea maka o ka ethylene oxide, ʻo ia ka monomer maka i hoʻohana nui ʻia i ka ʻoihana synthesis kemika, i ke kaʻina o ka hopena ethoxylation, me ka ka hoʻohui ʻana o ka ethylene oxide i ka waiʻona momona e hoʻohua ai i ka waiʻona momona ethoxylated, Aia kekahi ʻāpana liʻiliʻi o ka ethylene oxide (EO) ʻelua ʻelua mau molekele condensation e hana i kahi huahana, ʻo ia hoʻi, ka ʻenemi o ka dioxane, hiki ke hōʻike ʻia ka hopena kikoʻī. ma keia kii:
Ma keʻano laulā, loaʻa i nā mea hana maka i nā hana ma hope e hoʻokaʻawale a hoʻomaʻemaʻe i ka dioxane, ʻokoʻa nā mea hana ʻokoʻa i nā kūlana like ʻole, nā mea hana hoʻonaninani multinational e hoʻomalu i kēia hōʻailona, ma kahi o 20 a 40ppm.E pili ana i ka maʻamau maʻamau i ka huahana i hoʻopau ʻia (e like me ka shampoo, holoi kino), ʻaʻohe mea hōʻailona honua.Ma hope o ka hanana shampoo Bawang i ka makahiki 2011, ua hoʻonohonoho ʻo Kina i ka maʻamau no nā huahana i hoʻopau ʻia ma lalo o 30ppm.
ʻO Dioxane ke kumu o ka maʻi kanesa, ke kumu paha ia i nā hopohopo palekana?
Ma ke ʻano he mea maka i hoʻohana ʻia mai ke Kaua Honua II, ua aʻo nui ʻia ka sodium sulfate (SLES) a me kāna huahana dioxane.Ke aʻo nei ka United States Food and Drug Administration (FDA) i ka dioxane i nā huahana mea kūʻai aku no 30 mau makahiki, a ua manaʻo ʻo Health Canada ʻo ka loaʻa ʻana o ka nui o ka dioxane i loko o nā huahana cosmetic ʻaʻole ia he pilikia olakino i nā mea kūʻai aku, ʻo nā keiki (Kanada). ).Wahi a ka Australian National Occupational Health and Safety Commission, ʻo ka palena kūpono o ka dioxane i nā mea kūʻai aku ʻo 30ppm, a ʻo ka palena kiʻekiʻe o ka toxicologically ʻae ʻia he 100ppm.Ma Kina, ma hope o ka makahiki 2012, ʻo ka palena palena o 30ppm no ka dioxane content i loko o nā mea hoʻonaninani ʻoi aku ka liʻiliʻi ma mua o ka palena kiʻekiʻe toxicologically ʻae ʻia o 100ppm ma lalo o nā kūlana hoʻohana maʻamau.
Ma ka ʻaoʻao ʻē aʻe, pono e hoʻokūpaʻa ʻia ka palena o ka dioxane o Kina i nā kūlana cosmetic ma lalo o 30ppm, kahi kūlana kiʻekiʻe ma ka honua.No ka mea ʻoiaʻiʻo, ʻoi aku ka nui o nā ʻāina a me nā ʻāina i nā palena kiʻekiʻe o ka maʻiʻo dioxane ma mua o kā mākou maʻamau a ʻaʻole maopopo.
ʻO ka ʻoiaʻiʻo, maʻamau ka nui o ka dioxane ma ke ʻano.ʻO ka US Toxic Substances and Disease Registry ka papa inoa o ka dioxane i loaʻa i loko o ka moa, nā tōmato, ka ʻōpae a me ka wai inu.Wahi a ka World Health Organization Guidelines for Drinking Water Quality (Third edition) ʻo ka palena o ka dioxane i loko o ka wai he 50 μg/L.
No laila, e hōʻuluʻulu i ka pilikia carcinogenic o dioxane i hoʻokahi huaʻōlelo, ʻo ia hoʻi: me ka nānā ʻole i ke ʻano e kamaʻilio e pili ana i ka pōʻino he rogue.
ʻO ka haʻahaʻa haʻahaʻa o ka dioxane, ʻoi aku ka maikaʻi o ka maikaʻi, pololei?
ʻAʻole ʻo Dioxane wale nō ka hōʻailona o ka maikaʻi SLES.ʻO nā mea hōʻailona'ē aʻe e like me ka nui o nā pūhui unsulfonated a me ka nui o nā mea hoʻonāukiuki i loko o ka huahana he mea nui hoʻi e noʻonoʻo.
Eia kekahi, he mea nui e hoʻomaopopo i ka hiki ʻana mai o SLES i nā ʻano nui like ʻole, ʻo ka ʻokoʻa nui loa ka degere o ka ethoxylation, kekahi me 1 EO, kekahi me 2, 3 a i ʻole 4 EO (ʻoiaʻiʻo, nā huahana me nā wahi decimal e like me 1.3 a hiki ke hana ʻia ka 2.6).ʻO ke kiʻekiʻe o ke kiʻekiʻe o ka hoʻonui ʻana i ka ethoxidation, ʻo ia hoʻi, ʻoi aku ka kiʻekiʻe o ka helu o EO, ʻoi aku ka kiʻekiʻe o ka ʻike o ka dioxane i hana ʻia ma lalo o ke kaʻina hana like a me nā kūlana hoʻomaʻemaʻe.
ʻO ka mea hoihoi naʻe, ʻo ke kumu o ka hoʻonui ʻana i ka EO, ʻo ia ka hoʻēmi ʻana i ka mea hoʻonāukiuki o ka surfactant SLES, a ʻoi aku ka kiʻekiʻe o ka helu EO SLES, ʻoi aku ka liʻiliʻi o ka hoʻonāukiuki i ka ʻili, ʻo ia hoʻi, ʻoi aku ka maʻalahi, a me ka hope.Me ka ʻole o EO, ʻo ia ka SLS, ka mea i makemake ʻole ʻia e nā mea hoʻohui, he mea hoʻoulu nui loa ia.
No laila, ʻo ka haʻahaʻa haʻahaʻa o ka dioxane, ʻaʻole ia he kumu maikaʻi.No ka mea, inā liʻiliʻi ka helu EO, ʻoi aku ka nui o ka huhū o ka mea maka
Ma ka SUMMARY:
ʻAʻole ʻo Dioxane kahi mea hoʻohui i hoʻohui ʻia e nā ʻoihana, akā he mea maka e pono ke waiho i nā mea maka e like me SLES, he paʻakikī ke pale aku.ʻAʻole wale ma SLES, ʻoiaʻiʻo, i ka wā e hoʻokō ʻia ai ka ethoxylation, e loaʻa nā ʻāpana o ka dioxane, a aia kekahi mau mea mālama ʻili i loko o ka dioxane.Mai ka manaʻo o ka loiloi pilikia, ma ke ʻano he mea koena, ʻaʻohe pono e alualu i ka ʻike 0 piha, e lawe i ka ʻenehana ʻike i kēia manawa, "ʻaʻole i ʻike ʻia" ʻaʻole ia he 0 ka ʻike.
No laila, ʻo ke kamaʻilio e pili ana i ka pōʻino ma waho aʻe o ke ʻano he gangster.Ua aʻo ʻia ka palekana o ka dioxane no nā makahiki he nui, a ua hoʻokumu ʻia ka palekana kūpono a me nā kūlana i manaʻo ʻia, a ʻo nā koena ma lalo o 100ppm i manaʻo ʻia he palekana.Akā ʻaʻole i hoʻolilo nā ʻāina e like me ka European Union i mea maʻamau.ʻO nā koi kūloko no ka ʻike o ka dioxane i nā huahana ma lalo o 30ppm.
No laila, ʻaʻole pono ka dioxane i ka shampoo e hopohopo e pili ana i ka maʻi kanesa.E pili ana i ka kuhi hewa ʻana i ka media, ʻike ʻoe i kēia manawa ʻo ia wale nō ka nānā ʻana.
