A skin and eye irritant; May cause headache and confusion; [CAMEO] May cause irritation; May cause skin sensitization; [MSDSonline] "Turpentine and the monoterpenes (alpha-pinene, beta-pinene, 3-carene) are skin and mucous membrane irritants, and in high concentrations, are central nervous system (CNS) depressants." A dermal sensitizer; [ACGIH] The allergens in turpentine are hydroperoxides of delta-3-carene with higher concentrations in Indonesian than in Portuguese turpentine. [Kanerva, p. 1766] Occupational asthma confirmed in hospital lab technician to a bicyclic terpene from latex gloves, probably 3-Carene; [Malo] See "Turpentine." See "TERPENES."
