The most significant incident occurred in 2005 when the photoinitiator ITX<\/a> was detected in Nestl\u00e9 infant formula in Italy. Globally, the European Union maintains the strongest focus on the health impacts of chemicals and enforces the most stringent regulations.<\/p>\n

Toksikolojik S\u0131n\u0131fland\u0131rma ve TPO Kullan\u0131m\u0131na \u0130li\u015fkin K\u0131s\u0131tlamalar<\/strong><\/h3>\n

With the widespread use of the fotoba\u015flat\u0131c\u0131 TPO<\/a>, regulatory oversight has intensified. Under the EU’s CLP (Classification, Labelling, and Packaging) Regulation, TPO was initially classified as a Category 2 (H361) reproductive toxicant, meaning \u201csuspected human reproductive toxicant, but the available evidence is not sufficient to conclusively classify it as Category 1.\u201d<\/p>\n

TPO (MAPO)<\/strong><\/h3>\n

Haziran 2020'de, bir \u0130skandinav \u00fclkesi olan \u0130sve\u00e7, s\u0131n\u0131fland\u0131rman\u0131n Kategori 1B (H360DF) olarak revize edilmesini ve cildi tahri\u015f edici (H317) olarak eklenmesini \u00f6nerdi. Kategori 1B, hayvan \u00e7al\u0131\u015fmalar\u0131ndan elde edilen \u00f6nemli kan\u0131tlara dayanan bir sonu\u00e7 olan \"insan \u00fcremesine toksik oldu\u011fu varsay\u0131lan\" anlam\u0131na gelir.<\/p>\n

Kategori 1A maddeleri yasaklan\u0131rken, Kategori 1B maddelerinin yasaklanmas\u0131 veya k\u0131s\u0131tlanmas\u0131 muhtemeldir. Daha \u00f6nce, bir \u0130skandinav \u00fclkesi olan \u0130sve\u00e7 de s\u0131n\u0131fland\u0131rman\u0131n 1B (H360DF) olarak de\u011fi\u015ftirilmesini ve cilt tahri\u015f edici (H317) olarak eklenmesini \u00f6nermi\u015fti.<\/p>\n

2021 sonbahar\u0131nda, AB'nin Risk De\u011ferlendirme Komitesi (RAC) TPO'nun s\u0131n\u0131fland\u0131rmas\u0131n\u0131 g\u00fcncellemeyi kabul etti. Avrupa Komisyonu (EC) \u015fu anda bu s\u0131n\u0131fland\u0131rmay\u0131 g\u00f6zden ge\u00e7iriyor ve bu s\u00fcrecin y\u00f6netmeliklere g\u00f6re 0,5-1,5 y\u0131l s\u00fcrmesi bekleniyor. EC taraf\u0131ndan onaylan\u0131rsa, bu s\u0131n\u0131fland\u0131rma bir ATP arac\u0131l\u0131\u011f\u0131yla AB CLP T\u00fcz\u00fc\u011f\u00fc Ek VI'ya eklenecek ve yasal olarak ba\u011flay\u0131c\u0131 hale gelecektir.

Bu, TPO'nun art\u0131k g\u0131da ile temas eden malzemeler gibi bir\u00e7ok uygulamada yasakland\u0131\u011f\u0131 veya k\u0131s\u0131tland\u0131\u011f\u0131 anlam\u0131na geliyor.<\/p>\n

TPO Alternatif Se\u00e7enekleri<\/strong><\/h3>\n

UVA band\u0131nda iyi absorpsiyona sahip fosfin oksit fotoba\u015flat\u0131c\u0131lar aras\u0131nda TPO'nun yan\u0131 s\u0131ra yayg\u0131n olarak kullan\u0131lan di\u011fer iki alternatif TPO-L ve 819'dur (BAPO). Ancak, TPO-L ve 819 belirli uygulamalarda TPO'nun yerini sadece k\u0131smen alabilir ve tamamen ikame edemez.<\/p>\n

\"\"TPO-L, TPO'ya benzer bir yap\u0131ya sahiptir, ancak molek\u00fcl\u00fcndeki bir benzen halkas\u0131 bir etoksi grubu ile ikame edilmi\u015ftir, bu da daha d\u00fc\u015f\u00fck toksisite ile sonu\u00e7lan\u0131r. Bununla birlikte, TPO-L, TPO'ya k\u0131yasla \u00f6nemli \u00f6l\u00e7\u00fcde daha d\u00fc\u015f\u00fck ba\u015flatma etkinli\u011fi sergiler.<\/p>\n

TMO, tam olarak (2,4,6-trimetilbenzoil) bis (p-tolil) fosfin oksit, CAS 270586-78-2 olarak bilinir. Yap\u0131sal olarak TMO, TPO'ya dayanan iki benzen halkas\u0131n\u0131n her birine bir metil grubu ekleyerek TPO'nun biyotoksisitesini \u00f6nemli \u00f6l\u00e7\u00fcde azalt\u0131r. Deneysel bulgular, TMO'nun TPO'ya k\u0131yasla biraz daha \u00fcst\u00fcn ba\u015flatma etkinli\u011fi sergiledi\u011fini ve ayn\u0131 zamanda sararma ve daha d\u00fc\u015f\u00fck migrasyon g\u00f6stermedi\u011fini g\u00f6stermektedir.<\/p>\n
