Used as a plasticizer and chemical intermediate; also used as an additive to explosives, varnishes, lacquers, insecticides, fungicides, pharmaceuticals, cosmetics, and flavorings; [ACGIH] |
Comments |
Workers exposed to greater than 2 ppm (12.6 mg/m3) report irritation of the eyes and nose and loss of the sense of smell. Camphor causes convulsions in experimental animals and in humans after ingestion of high doses. [ACGIH] Can cause nonimmunologic contact urticaria; [Kanerva 2004, p. 103] |
