Description of key information
The search for a mutagenic activity of the test item L-Leucine, reaction products with 1,4:3,6- dianhydro-D-glucitol, iso-Pr alc. and octanoyl chloride (batch 200122016662) sponsored by SEPPIC SA was done by means of the Ames’ test in the five Salmonella typhimurium strains TA1535, TA1537, TA98, TA100 and TA102 tested both in presence and in absence of metabolic activation, in two independent assays according to OECD guideline (OECD 471, 1997), using the maximum recommended dose, i.e. 5000 µg/plate.
The acceptance criteria for the assay were considered as fulfilled. The current study was valid. Under these experimental conditions, no mutagenic activity was revealed.

- Evaluation criteria:
- Sterility controls are presented in Appendix No. 2, Table 4.
After spreading out the test item alone under the conditions of the preliminary toxicity assay and after approximately 67-hour incubation at ca. 37°C, no colony was visible.
Historical data are shown in Appendix No. 3.
The frequencies of spontaneous revertants (solvent controls) were within the limits generally observed under our experimental conditions.
Concurrently to the main assays, tests were carried out on reference mutagenic test compounds in order to show the sensitivity of the strains tested and the efficiency of the metabolic activation system. Statistically and biologically significant increases in the numbers of revertants were observed in the presence of positive reference test substances. The values observed were greater than the lowest limit of historical controls.
At least 5 doses, with at least 2 plates per dose, were available for the assessment of mutagenicity, as required by OECD guideline (471, 1997) except in the 2nd assay in presence of metabolic activation in strain TA1537 (see Table 11 and § 14). - Statistics:
- In parallel, data were analysed by means of Dunnett's method (Mahon et al, 1989) allowing the comparison of the mean value for each dose to the mean value for the corresponding solvent control. Statistical methods may be used as an aid in evaluating the test results. However, statistical significance should not be the only determining factor for a positive response and biological relevance of the results should be considered first.
Providing that all acceptability criteria are fulfilled, a test item is considered to be clearly positive if, in any of the experimental conditions examined all the following criteria are fulfilled: - at least one of the test doses exhibits a biologically significant increase (2 or 3 fold increase in the mean number of revertants depending on the strain) compared with the concurrent negative control and,
- the increase is dose-related,
- and the mean numbers of revertants of the test doses are outside the distribution of negative control data
The test item is then considered able to induce mutations in this test system.
If, in all experimental conditions examined, none of the above criteria are fulfilled, a test item is considered clearly negative and unable to induce mutations in this test system. - Key result

PURPOSE
The search for any mutagenic activity of L-Leucine, reaction products with 1,4:3,6-dianhydro-D glucitol, iso-Pr alc. and octanoyl chloride (Batch 200122016662) sponsored by SEPPIC SA was studied by means of the Ames’ test (Salmonella his-/microsome system) in compliance with the Commission Regulation EC 440/2008 and the OECD Guideline 471 and its anticipated deviation (see § 12), using the maximum recommended dose, i.e. 5000 µg/plate.
All the doses tested in this study are expressed as µg/plate of pure L-Leucine, reaction products with 1,4:3,6-dianhydro-D-glucitol, iso-Pr alc. and octanoyl chloride.
METHODS
Study carried out on 5 strains both with and without metabolic activation using hepatic microsomes from rat livers induced by Aroclor 1254 – Incubation period: ca. 48 h
Strains used Salmonella typhimurium TA1535, TA1537, TA98, TA100, TA102 Solvent DMSO
Stability in the solvent unknown (preparations for treatments were thus prepared extemporaneously)
Purity 98.6%
Correction factor 1.014
Expression of the doses
used in the assays µg/plate of pure L-Leucine, reaction products with 1,4:3,6- dianhydro-D-glucitol, iso-Pr alc. and octanoyl chloride.
RESULTS
In 2 independent assays performed both with and without metabolic activation (the second assay was carried out according to the pre-incubation protocol), no biologically significant increases in the number of revertants were noted whatever the strain and the metabolic activation condition tested.
The test item L-Leucine, reaction products with 1,4:3,6-dianhydro-D-glucitol, iso-Pr alc. and octanoyl chloride is thus considered as devoid of mutagenic hazard.
CONCLUSION
The search for a mutagenic activity of the test item L-Leucine, reaction products with 1,4:3,6- dianhydro-D-glucitol, iso-Pr alc. and octanoyl chloride (batch 200122016662) sponsored by SEPPIC SA was done by means of the Ames’ test in the five Salmonella typhimurium strains TA1535, TA1537, TA98, TA100 and TA102 tested both in presence and in absence of metabolic activation, in two independent assays according to OECD guideline (OECD 471, 1997), using the maximum recommended dose, i.e. 5000 µg/plate.
The acceptance criteria for the assay were considered as fulfilled. The current study was valid. Under these experimental conditions, no mutagenic activity was revealed.
