E110ColorantElevated concern
Sunset Yellow FCF
In plain words
The short version
A bright orange synthetic azo dye used in soft drinks, candies, and snack foods.
Why we flag it
A synthetic orange dye (Sunset Yellow / Yellow 6). It adds colour only, and it's one of the dyes linked in studies to hyperactivity in some children, so the EU requires a warning label. That's why we flag it.
Safety profile
ADI of 4 mg/kg body weight (EFSA 2014 re-evaluation). Identified in the Southampton study as one of six dyes linked to increased hyperactivity in some children — EU labelling requires the warning 'May have an adverse effect on activity and attention in children'. Aspirin-sensitive individuals can develop urticaria.
