title: Sudan I as a cause of pigmented contact dermatitis in "kumkum" (an Indian cosmetic).
abstract: "Kumkums" are coloured cosmetics frequently applied to the center of the forehead by Hindu women. Pigmented allergic contact dermatitis to "kumkum" was reported recently. It was associated with Brilliant Lake Red R and Sudan I allergy. These might be the causative allergens. Three of 7 brands of red "kumkums" analyzed by gas chromatography-mass spectrophotometry were found to contain various concentrations of Sudan I. They ranged from 2.789 mg/gm to 8.694 mg/gm. Sudan I is probably the cause of pigmented allergic contact dermatitis in red "kumkum".
