title: [The formaldehyde problem].
abstract: Regarding formaldehyde (FA), we face the following problems: (1) It is a wide-spread substance being found as free FA, in FA releasers and FA resins. (2) FA contact allergy occurs either as occupational or non-occupational disease. (3) In spite of its frequency there are still problems concerning patch testing of FA. We report on the results of patch testing with FA in various vehicles and concentrations performed on patients with dermatitis and those suffering from a proven FA contact allergy. Our investigations confirm the superiority of water as a vehicle.
