- Details on test system and experimental conditions:
- These platings were achieved by the following sequence of additions to 2.5 mL molten agar at 46°C:
0.1 mL bacterial culture
0.025 mL test article solution or control
0.5 mL 10% 8-9 mix or buffer solution
followed by rapid mixing and pouring on to Minimal Davis agar plates. When set, the plates were inverted and incubated at 37°C in the dark for 3 days. Following incubation, these plates were examined for evidence of toxicity to the background lawn, and where possible revertant colonies were counted. - Evaluation criteria:
- The test article was considered to be mutagenic if: 1) the assay was valid, 2) Dunnett’s test gave a significant response (p<0.01), and the data set(s) showed a significant dose-correlation, and 3) the positive responses described in 2) were reproducible.
- Statistics:
- The m-statistic was calculated to check that the data were Poisson-distributed, and Dunnett’s test was used to compare the counts of each dose with the control. The presence or otherwise of a dose response was checked by linear regression analysis.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
The test to assess the genotoxicity of the test material was negative. This finding does not warrant the classification of this test material as a genotoxin under the new Regulation (EC) 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP) or under Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations. - Executive summary:
No SHELLSOL TD treatments of any of the test strains, either in the absence or in the presence of S-9, resulted in a statistically significant increase in revertant numbers, when the data were analysed at the 1% level using Dunnetts test. This study was therefore considered to have provided no indication of any SHELLSOL TD mutagenic activity. The test to assess the genotoxicity of the test material was negative. This finding does not warrant the classification of this test material as a genotoxin under the new Regulation (EC) 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP) or under Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.
