Hypopigmentation from UV resin additive

Abstract
An employee formulating a UV‐resin based vehicle developed hypopigmentation limited to the forearms without preceding overt dermatitis. Manual procedures in an automatic process provided opportunity for exposure and contact to various components. A non‐resin additive, quinone, alone or in conjunction with a likely contaminant, hydroquinone, was the suspected agent. Patch tests to quinone caused severe irritation. Reactions to acrylic components were not felt to be directly pertinent.
