ABSTRACT
A sodium salt of ethylenediaminetetraacetate (Na3EDTA) and ethylenediamine (EDA) were subjected to a repeated insult patch test on Hartley albino guinea pigs (10 per compound). All guinea pigs (10 of 10) receiving EDA were sensitized. None of the guinea pigs (0 of 10) was sensitized to Na3 EDTA. Likewise, none of the guinea pigs sensitized to EDA reacted positively when challenged with Na3 EDTA. Based on these results, it is concluded that EDTA is not likely to be a sensitizer to humans, and would not likely cross-sensitize with EDA. In addition, the presence of very small amounts of the sodium salts of EDTA in cosmetic and pharmaceutical preparations does not represent an appreciable risk of human skin sensitization.
