Allergic contact dermatitis from triglycidyl isocyanurate in polyester paint pigments.
Contact Dermatitis 1988 Jul; 19(1):67-68
A case of allergic contact dermatitis from triglycidyl-isocyanurate (2451629) in polyester paint pigments was described in a 25 year old male who worked for a outdoor light fixture manufacturer. He had worked for 4 months doing general duties and 2 months as a paint sprayer, which involved electrostatic charging of powdered polyester paint pigments and opposite charging of metallic surfaces to be painted. Painters wore half face cartridge respirators, latex gloves, and disposable paper suits and hoods. The painted light fixtures were heat cured in an oven immediately after painting. The employee developed severe dermatitis of the ears, forehead, perioral skin and cheeks near the eyes within 2 weeks of the start of a new work procedure which required painters to enter the booth at the end of the shift and use air hoses and scrapers to dislodge pigments from the walls. A return of episodes of dermatitis followed his return to spray painting. Tests of the principal ingredients in the paint showed that triglycidyl-isocyanurate gave a 2+ reaction at both 48 and 96 hours whereas polyester resin was negative. On the safety data sheets from the manufacturer triglycidyl-isocyanurate was listed as a mild skin sensitizer. Changes were made at the company so that workers no longer used air hoses inside the spray booths, eliminating unnecessary airborne exposure.
