Quinoline yellow, Quinoline Yellow WS, C.I. 47005, or Food Yellow 13, is a yellow food dye. Chemically it is a mixture of disulfonates (principally), monosulfonates and trisulfonates of 2-(2-quinolyl) indan-1,3-dione. It is also listed under CAS number [].
Quinoline Yellow SS (Spirit Soluble) is its form insoluble in water. It lacks the sulfonate group.

[edit] Uses
It is more commonly known as E104 in terms of E numbers. It is a food colorant that induces a dull yellow, or greenish yellow colour. It can be found in ices, cough sweets, scotch eggs and smoked haddock. It is one of the colors that the Hyperactive Children's Support Group recommends be eliminated from the diet of children. It may cause contact dermatitis. Whilst being a commonly used color in the UK, its use is banned in Japan and the United States. It was banned in Australia but its use has been permitted since 2003.
It is used as a pigment for tattoos.
[edit] Health effects
A study commissioned by the UK's Food Standards Agency found that when used in a mixture of other preservatives, increased levels of hyperactivity and decreased levels of intelligence in children were observed.[1][2]
