Cross-reactions between ethylenediamine, diethylenetriamine and triethylenetetramine.

A consecutive series of 1544 patients and 137 patients in occupational contact with epoxy resins were tested with ethylenediamine and/or triethylenetetramine; some were tested with diethylenetriamine. Guinea pigs sensitized to triethylenetetramine were tested with ethylenediamine and diethylenetriamine. The results showed that cross-reactions may occur between triethylenetetramine and ethylenediamine, although the majority of the patients were sensitized to only one of the compounds.
