Contact allergy to 3-methylol phenol, 2,4-dimethylol phenol and 2,6-dimethylol phenol. 1985

M Bruze, and E Zimerson

Thirteen patients with contact allergy to phenol-formaldehyde resins (P-F-R) were patch tested with 3-methylol phenol, 2,4-dimethylol phenol and 2,6-dimethylol phenol. Nine patients reacted to at least 1 compound, all giving positive test responses to 2,4-dimethylol phenol. Seven patients reacted simultaneously to 2,6-dimethylol phenol while only 1 patient reacted to 3-methylol phenol. Negative test responses were noted in 20 controls. Chemical investigation by high pressure liquid chromatography indicated that the compounds tested were pure and separable. The 3 reported sensitizers may, theoretically, be generated during the manufacture of P-F-R. 2,4-Dimethylol phenol and 2,6-dimethylol phenol have been demonstrated and there has been chromatographic evidence of 3-methylol phenol in the P-F-R used in the routine test series at the department.

D005557 Formaldehyde A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717) Formalin,Formol,Methanal,Oxomethane
