Orange monoazo dye used in artificial colorants. Soluble in water or glycerol but only slightly soluble in ethanol. Has a reddish-yellow hue in concentrated solution that becomes yellow on dilution; the dye is colour stable at extrusion temperatures, pH 3-8 and in the presence of organic acids and alkalis commonly used in food processing, such as citric acid and sodium bicarbonate. Sunset Yellow is often blended with tartrazine and used in colorants for low fat spreads. Also used, in combination with other colorants, to colour a range of products, including bakery products, beverages (e.g. cola beverages), sugar confectionery and ice cream. Also known as FD&C Yellow No. 6 and Food Yellow 3 and CI 15985.
