Ponceau 4R is a synthetic, red azo dye.
Ponceau 4R may cause a reaction in individuals with salicylate allergies. The dye has been mildly associated with hyperactivity in children. A 2001 review of safety data on the dye, by the European Food Safety Authority, concluded that Ponceau 4R did not pose a risk at current consumption levels.
Ponceau 4R is not permitted for use in the US and was voluntarily phased out in the UK following consumer demand.
