The in vitro gene mutation test, mammalian cell gene mutation assay, did not show any mutagenic effect.

The results of the in vivo micronucleous assay is negative.

Based on these tests, Direct Red 81 could be considered as not mutagenic.

Endpoint Conclusion: No adverse effect observed (negative)
