Descrição geral

Sunset yellow FCF is a food dye, which is is substantially used in various food preparations.[1] It is a orange-red coloured crystal, that is soluble in water and ethanol.[2] It is used in treating bone metabolic diseases, dermatological disorders, respiratory illness etc.[2] It can alter the functional responses of splenocytes at non-cytotoxic dose. It promotes immune suppression. Relative expression of surface receptors in T and B cells can be altered by sunset yellow FCF.[1]

Sunset yellow FCF is a synthetic sulfonated monoazo dye,[3] which belongs to the class of azo dyes.[4] It is used in pharmaceuticals and cosmetics. Sunset yellow FCF is associated with asthma, immunosuppression, eczema, cancer and anxiety migraine.[4]

Aplicação

Sunset yellow FCF has been used to determine anaerobic biodegradability of azo dyes in the continuous and catalytic upflow stirred packed-bed reactor (USPBR) system.[5]
