Dioxane? Nibibazo byurwikekwe

Dioxane ni iki? Byaturutse he?

Dioxane, inzira nziza yo kwandika ni dioxane. Kuberako ikibi kiragoye kwandika, muriyi ngingo tuzakoresha amagambo asanzwe aho. Nibibazo kama, uzwi kandi nka Dioxane, 1, 4-dioxane, amazi atagira ibara. Uburozi bukabije bwa dioxane ni uburozi buke, bufite ingaruka zikomeye kandi zitera imbaraga. Ukurikije amategeko yubuhanga bwo kwisiga mubushinwa mu Bushinwa, Dioxane ni ikintu cyabujijwe amavuta yo kwisiga. Kubera ko bibujijwe kongeraho, kuki kwisiga biracyafite detection ya dioxane? Kubwimpamvu za tekiniki zidashobora kwirindwa, birashoboka kuri dioxane zitangizwa mugukora amavuta nkumwanda. None ni ubuhe buryo bwanduye mu bikoresho fatizo?

Kimwe mu bintu bikoreshwa cyane muri Shampoos no mu cyumubiri ni SOTH ibinure bya sodium inzoga ether sulfate, nanone uzwi kandi nka sodium aes cyangwa sles. Ibi bigize birashobora gukorwa mumavuta yimikindo karemano cyangwa peteroli nkibikoresho fatizo mubitago bya alcool, ariko birakoreshwa binyuze murukurikirane rwintambwe nka ethoxtion, sulhore. Intambwe y'ingenzi ni ethoxtion, muri iyi ntambwe yo kwigishwa, ugomba gukoresha ibikoresho bibisi bya okhoy of Syytheside Compansation yo kubyara ibicuruzwa, ni ukuvuga umwanzi wa Diyoxane, reaction yihariye irashobora kwerekanwa mu ishusho ikurikira:

Muri rusange, abakora ibintu fatije ibikoresho bizagira intambwe nyuma yo gutandukana no kweza dioxane, abakora ibikoresho bitandukanye bizagira ibipimo bitandukanye, abakora amavuta manyereza kandi bazagenzura kandi ibipimo ngenderwaho, muri rusange 40 kugeza 40. Naho ibipimo biri mu bicuruzwa byarangiye (nka Shampoo, gukaraba umubiri), nta bipimo mpuzamahanga byihariye. Nyuma yo kubona akazi ka bawang shampoo mu 2011, Ubushinwa bwashyizeho ibipimo byateganijwe ku bicuruzwa byarangiye munsi ya 30ppm.

Dioxane itera kanseri, bitera impungenge z'umutekano?

Nkuko ibikoresho bibisi bikoreshwa kuva Intambara ya Kabiri y'Isi Yose, sodiyumu sulfate (sles) hamwe nibicuruzwa bya dioxane byiga cyane. Ubuyobozi bw'Ubumwe n'Ubuyobozi bw'ibiyobyabwenge (FDA) bwiga Dioxane mu gihe cy'ibicuruzwa ku myaka 30, naho Kanada yanzuye ko muri Dioxxane zingana na Dioxxane mu bicuruzwa byo kwisiga bitaba ibyago byo kubaguzi, ndetse n'abana (Kanada). Dukurikije Komisiyo ishinzwe ubuzima n'umutekano muri Ositaraliya, urugero rwiza rwa Dioxane mu bicuruzwa by'umuguzi ni 30ppm, n'urugero rwo hejuru rwo kwemerwa na 100ppm. Mu Bushinwa, nyuma ya 2012, imipaka ntarengwa ya 30ppm kubice bya dioxane muri kwisiga byakarenze kure cyane kurenza urugero rwa 100ppm zikoreshwa bisanzwe.

Ku rundi ruhande, bigomba gushimangirwa ko ubushinwa bwa dioxane mu mavuta yo kwisiga butarenze 30ppm, ari yo mahame yo hejuru ku isi. Kuberako mubyukuri, ibihugu byinshi nuturere bifite imipaka yo hejuru kubirimo bya dioxane kuruta ibipimo byacu cyangwa nta bipimo bisobanutse:

Mubyukuri, umubare munini wa dioxxane nawo urasanzwe muri kamere. Ibintu byuburozi muri Amerika hamwe na bagorekeje urugamba urutonde rwa dioxane nkuko tubisanga mu nkoko, inyanya, shimp ndetse no mumazi yo kunywa. Amabwiriza y'imikorere y'ubuzima ku bumenyi bw'amazi (integuro ya gatatu) ivuga ko imipaka ya Dioxane mu mazi ari 50 μg / l.

Kugira ngo rero, muri make ikibazo cya carcinogenic cya dioxane mu nteruro imwe, ni: utitaye ku gipimo cyo kuvuga ku kibi ni ikigoga.

Hasi ibiri muri dioxane, nibyiza ubuziranenge, nibukuri?

Dioxane ntabwo aricyo kimenyetso cyonyine cyubwiza. Ibindi bipimo nkikigereranyo kidacogora kandi umubare wabangamizi mubicuruzwa nawo ni ngombwa kugirango usuzume.

Byongeye kandi, ni ngombwa kumenya ko Sles nazo ziza mu bunini butandukanye, itandukaniro rinini kuba urwego rwa EOThoxtion, bamwe hamwe na 1 EO, na 4 EO (birumvikana kandi ko ibicuruzwa bifite aho bigera kuri 1.3 na 2.6 birashobora gukorwa). Urwego rwo hejuru rwo kwiyongera Ethoxidation, ni ukuvuga umubare wa EO, hejuru yibiri muri dioxane byakozwe muburyo bumwe no kwezwa.

Igishimishije ariko, impamvu yo kongera Eo ni ukugabanya uburakari bwinshi, kandi umubare wa EO Sles, ntukarakaze kuruhu, ni ukuvuga, yoroheje, naho ubundi. Hatabayeho eo, ni sls, zidakunzwe nabakiriya, nikintu gishimishije cyane.

Kubwibyo, ibiri muri dioxane ntibisobanura ko byanze bikunze ari ibintu byiza. Kuberako niba umubare wa EO ari muto, kurakara ibikoresho byifatizo bizaba byinshi

Muri make:

Dioxane ntabwo ari ingirakamaro yongewe nimishinga, ariko ibikoresho fatizo bigomba kuguma mubikoresho bibisi nka sles, bigoye kwirinda. Ntabwo ari in Sles gusa, mubyukuri, ethoxrislation yakozwe, hazabaho dioxane ya dioxane, hamwe nibikoresho byo kwita ku ruhu bibisi birimo dioxane. Duhereye ku gusuzuma ingaruka, nk'ibintu bisigaye, nta mpamvu yo gukomeza ibintu byuzuye, fata ikoranabuhanga ritubahirizwa, "ritamenyekana" ntabwo bivuze ko ibirimo ari 0.

Rero, kuvuga ibyangiritse birenze urugero ni ukuba agatsiko. Umutekano wa Dioxane wizwe mumyaka myinshi, kandi umutekano ujyanye kandi usabwa ibipimo byatanzwe, kandi ibisigazwa bitarenze 100ppm bifatwa nkumutekano. Ariko ibihugu nkumuryango wumuryango wiburayi ntabwo wabigize amahame ateganijwe. Ibisabwa murugo kubikubiyemo Dioxane mubicuruzwa biri munsi ya 30ppm.

Kubwibyo, Dioxane muri Shampoo ntabwo ikeneye guhangayikishwa na kanseri. Naho amakuru atari yo mu bitangazamakuru, ubu umva ko ari ukureba gusa.
