|Section2= }} Sudan I (also commonly known as CI Solvent Yellow 14 and Solvent Orange R), is an organic compound, typically classified as an azo dye. It is an intensely orange-red solid that is added to colourise waxes, oils, petrol, solvents and polishes. Sudan I has also been adopted for colouring various foodstuffs, especially curry powder and chili powder, although the use of Sudan I in foods is now banned in many countries, because Sudan I, Sudan III, and Sudan IV have been classified as category 3 carcinogens (not classifiable as to its carcinogenicity to humans)〔http://monographs.iarc.fr/ENG/Classification/index.php〕 by the International Agency for Research on Cancer. Sudan I is still used in some orange-coloured smoke formulations and as a colouring for cotton refuse used in chemistry experiments. ==Toxicology== Sudan I is genotoxic. It is also carcinogenic in rats.〔Larsen, John Chr. "Legal and illegal colors" Trends in Food Science & Technology (2008), 19(Suppl. 1), S60-S65. 〕 Comparisons between experimental animals and human Cytochrome P450 (CYP) strongly suggest animal carcinogenicity data can be extrapolated to humans. Sudan I is also present as an impurity in Sunset Yellow, which is its disulfonated water-soluble version. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sudan I」の詳細全文を読む スポンサード リンク
