Dioxane? Ngumbandela nje ocalucalulo

Yintoni i-dioxane? Ivelaphi?

I-Dioxane, indlela echanekileyo yokubhala yi-dioxane. Kuba ububi bunzima kakhulu ukuba buchwetheze, kweli nqaku siza kusebenzisa amazwi aqhelekileyo endaweni engendawo. Yinto esebenzayo, ebizwa ngokuba yi-Dooxane, 1, 4-Dooxane, engenabala. Ityhefu yeDioxane ityhefu iphantsi kwetyhefu, ineziphumo zelizwi kunye nezibangela. NgokweKhowudi yangoku yoKhuseleko loKhuseleko lweZinto zeZinto zase China, dioxane yinto engavumelekanga ye-cosmetics. Kuba kunqatshelwe ukongeza, kutheni i-cosmetics isenayo ifunyanwe i-dioxane? Ngenxa yezizathu ezingenakuthintelwa, kunokwenzeka ukuba i-Dioxane ingeniswe kwi-cosmetics njengento engenanto. Ke yintoni ukungcola kwezinto ezingafunekiyo?

One of the most widely used cleansing ingredients in shampoos and body washes is sodium fatty alcohol ether sulfate, also known as sodium AES or SLES. Eli candelo linokwenziwa kwi-oyile yesundu yendalo okanye kwi-petroleum njengezinto ezinqabileyo kwii-alcoloty ezinamafutha, kodwa zihambelane nothotho lwamanyathelo anjenge-ethoxtration, ekuhlanjululwe, kunye nokungathathi cala. Inqanaba eliphambili yi-ETTEXY PROXICT, KULE NYANGO YOKUSETYENZISWA KOKUSETYENZISWA KOBUCHULE BENKONZO, EYENZIWEYO YENKQUBO YOKUZIPHATHA NGOKUGQIBILEYO KWI-ETHITY YE-ETYYE YENDLELA YOKUZIPHATHA Ukukhuthaza ukuvelisa imveliso yemveliso, oko kukuthi, utshaba lweDioxane, ukusabela okuthile kunokuboniswa kula manani alandelayo:

In general, raw material manufacturers will have later steps to separate and purify dioxane, different raw material manufacturers will have different standards, multinational cosmetics manufacturers will also control this indicator, generally about 20 to 40ppm. Ngokuphathelele umgangatho womxholo kwimveliso egqityiweyo (enjenge-shampoo, ukuhlamba umzimba), akukho zimpawu zikhethekileyo zamazwe athile. Emva kwe-Bawang Shampo Poaded ngo-2011, i-China ibeka umgangatho weemveliso ezigqityiweyo ezingaphantsi kwe-3mppm.

I-Dioxane ibangela umhlaza, ngaba ibangela inkxalabo yokhuseleko?

Njengesixhobo esingafunekiyo esisetyenziselwa ukususela kwiMfazwe Yehlabathi II, i-Sodium yeSodium (iSodium) kunye ne-Dioxane yayo ifundiwe kakhulu. I-United States yokutya kunye nolawulo lweziyobisi (i-FDA) sele ifundwe i-Dioxane kwiimveliso zabathengi iminyaka engama-30, kwaye iCanada yezeMpilo igqibe ekubeni ubukho bemveliso ye-dioxane kwiimveliso ze-cosmetic zingenzi mngcipheko wokuthengisa, kwanabantwana (saseCanada). NgokweKhomishini yeSizwe yezeMpilo yeSizwe yezeMpilo yeSizwe yezeMpilo yase-Australia, umda ofanelekileyo weDioxane kwiZinto zabaThengi yi-30ppm, kunye nomda ophezulu wetyhefu eyamkelekileyo ngokwenyani yi-100PPMM eyamkelekileyo yi-100ppm. E China, emva ko-2012, umda we-30ppm ye-tioxane yomxholo kwi-cosmetics ingaphantsi komda ophezulu wetyhefu ye-100ppm phantsi kweemeko eziphezulu zokusebenzisa.

Kwelinye icala, kufuneka kugxininiswe ukuba umda we-china waseDioxane kwimigangatho ye-cosmetic ingaphantsi kwe-30PPMM, engumhlaba ophezulu emhlabeni. Kuba enyanisweni, amazwe amaninzi kunye nemimandla anemida ephezulu kumxholo weDioxane kunomgangatho wethu okanye akukho migangatho icacileyo:

Ngapha koko, izixa ze-dioxane ziqhelekileyo kwindalo. Izinto ezinetyhefu zase-US kunye nerejista yezifo zidweliswe i-dioxane njengokufumaneka kwinkukhu, iitamatisi, i-shrimp kunye namanzi ethu okusela. Izikhokelo zombutho wezeMpilo zeHlabathi zeMgangatho wokusela amanzi (uhlelo lwesithathu) luyekele umda we-dioxane emanzini ngama-50 μg / l.

Ke ukwenzela ingxaki ye-carcinogenic yeDioxane kwisivakalisi esinye, oko yile: Ngaphandle kwedosi yokuthetha malunga nokwenzakala kuyinto embizeni.

Ezantsi komxholo weDioxane, ongcono umgangatho, ekunene?

I-Dioxane ayisiyiyo kuphela isalathiso somgangatho we-SLES. Ezinye izikhombisi ezinje ngenani leendlela ezingachazwanga kunye nenani lobunzima kwimveliso kubalulekile ukuqwalasela.

Ukongeza, kubalulekile ukuba uqaphele ukuba i-SLES ize ngobukhulu obahlukeneyo, owona mahluko mkhulu we-ETHEXY PHITE, i-1, i-EO, i-EO, iimveliso ezinama-1.3 kunye no-2.6 zinokuveliswa). Inqanaba eliphezulu lokunyuka kwe-ethoxididotion, oko kukuthi, ukuphakama kwenani le-EO, okuphakathi komxholo weDDioxane waveliswa phantsi kwenkqubo enye kunye neemeko zokucoca.

Okubangela umdla, nangona kunjalo, isizathu sokwandisa i-EO kukunciphisa ukungakhathali kwe-SESSEAREENT, kunye nenani le-EO SLEs, kokukhona, ukucaphukisa kancinci, Ngaphandle kwe-EO, yi-SLS, engathandekiyo ngabathengisi, esikhuthazayo kakhulu.

Ke ngoko, umxholo osezantsi weDioxane awuthethi ukuba yinto elungileyo eluhlaza. Kuba ukuba inani le-EO lincinci, ukucaphukisa izinto ezingafunekiyo kuya kuba nkulu

Isishwankathelo:

I-Dioxane ayisiyonto yongezwa ngamashishini, kodwa izinto ezingafunekiyo ezimele zihlale kwizinto eziluhlaza ezifana ne-sles, ekunzima ukuyiphepha. Kungekuphela nje kwi-sles kuphela, enyanisweni, ukuba i-ethotsid yenziwa, kuya kubakho umkhondo we-Doxane, kwaye ezinye izixhobo zolusu lungaphezulu kwe-dioxane. Ukusuka kwinqanaba lokujonga uvavanyo lomngcipheko, njengento eshiyekileyo, akukho mfuneko yokuba ulandele ngokupheleleyo umxholo, thatha itekhnoloji yokuchonga okwangoku, "engavunyelwanga" oko akuthethi ukuba umxholo ngu-0.

Ke, ukuthetha ngengozi ngaphaya kwedosi kukuba yiqela lemigulukudu. Ukukhuseleka kukaDioxane kufundwe iminyaka emininzi, kwaye ukhuseleko olufanelekileyo kunye nokucetyiswayo sele kusekiwe, kwaye iintsalela ezingaphantsi kwe-100ppm zithathwa njengekhuselekileyo. Kodwa amazwe afana ne-European Union engayenzanga ingumgangatho onyanzelekileyo. Iimfuneko zasekhaya zomxholo weDioxane kwiimveliso zingaphantsi kwe-30ppm.

Ke ngoko, iDoxane e-shampoo ayifuni ukuba nexhala malunga nomhlaza. Ngokuphathelele okungalunganga kwimithombo yeendaba, ngoku uyaqonda ukuba kukufumana ingqalelo.
