Endpoint summary

Additional information

A test of bacterial gene mutagenicity was conducted for GSID 3056-1 according to the OECD TG 471 as adopted in 1997 (BASF SE 40M0788/11M281, 2012), with following strains: TA 98, TA 100, TA 1535 and TA 1537 and E. coli WP2 uvrA . The test concentrations ranged from 33 to 5000 µg/plate for the standard plate test with and without S9 mix, and from 10 to 2500 µg/plate for the preincubation test with and without S9 mix.

An increase in the number of his+ or trp+ revertants was neither observed in the standard plate test nor in the preincubation test either with or without S9 mix. Therefore the substance is not mutagenic in bacteria.

Short description of key information:
AMES test according to the OECD TG 471 (BASF SE 40M0788/11M281, 2012): negative

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

based on the available data (Ames test, negative), no classification of the test item according to either the EU Directive 67/548/EEC or the CLP Regulation (EC) No. 1272/2008 is needed.
