Appendix H
1,4-Diamino-2,3-Dihydroanthraquinone
BACKGROUND
ALTERNATIVE NAMES for 1,4-diamino-2,3-dihydroanthraquinone (DDA) (after 1972) include 1,4-diamino-2,3-dihydro-9,10-anthracenedione (before 1972) and leuco-1,4-diaminoanthraquinone. DDA is a component of the old violet-dye mixture.
TOXICOKINETICS
No data are available on the toxicokinetics of DDA.
TOXICITY SUMMARY
Effects in Humans
No data are available on the effects of DDA in humans.
Effects in Animals
No data are available on the systemic toxicity of DDA in animals.
Mutagenicity Studies
In a report by Lundy and Eaton (1994), DDA was found to produce positive results in the Ames assay. In a study by Brown and Brown (1976), as cited by Dacre (1979), DDA was reported to produce ''marginally adequate'' evidence of mutagenicity in the Ames assay.
SUBCOMMITTEE EVALUATION OF DYE TOXICITY
Experimental data are insufficient to assess the toxic effects of DDA.
