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.
The color Quinoline Yellow SS (Spirit Soluble), which lacks the sulfonate groups, is a related form that is insoluble in water.

[edit] Uses
As a food additive with the E number E104, it is used as colorant that induces a dull yellow, or greenish yellow color.
[edit] Health effects
A study commissioned by the UK's Food Standards Agency found that a mixture of food colors and preservatives increased levels of hyperactivity and decreased levels of intelligence in children,[2][3] but it is unclear which component of the mixture may be responsible for the effects.[4] Quinoline yellow is one of the colors that the Hyperactive Children's Support Group recommends be eliminated from the diet of children.
UK ministers have agreed that six colorings will be phased out by 2009.[5]
EFSA has decided on 2009-09-23 to tighten the allowed Acceptable Daily Intake for Quinoline Yellow WS from 10 mg/kg to 0.5 mg/kg bodyweight per day. It's been reported to cause urticaria and rhinitis. The color additive can also increase the intake of aluminum beyond the tolerable weekly intake (TWI) of 1 mg/kg/week. Therefore the limit for aluminum may become adjusted to accommodate for this. Also the EFSA panel noted that the JECFA limit for lead is ≤ 2 mg/kg whereas the European Commission limit is ≤ 10 mg/kg.[6]
