||Immunologic contact urticaria due to airborne methylhexahydrophthalic and methyltetrahydrophthalic anhydrides
||Apr. 1995, Vol.32, No.4, p.204-209. Illus. 24 ref.
||Phthalic anhydrides used as hardeners for epoxy resins are known to cause respiratory irritancy and allergy. Skin allergy has on rare occasions been reported. Two workers developed urticaria on uncovered skin after 2 months airborne exposure to methyltetrahydrophthalic anhydride and methylhexahydrophthalic anhydride. Later, the patients also developed conjunctivitis, rhinitis, sore throat or asthma. Both patients' immediate allergy to these anhydrides was proved by different tests. On prick testing, both patients also reacted to phthalic anhydride. The patients had developed airborne contact urticaria, in addition to respiratory allergy, due to phthalic anhydrides.
