Description of key information
The registered substance was tested under OECD 471 guidelines and was found not to induce point mutations for frame-shift mutations with and without metabolic activation in TA 97, TA 98, TA 100, TA 102 or TA 1535 stains of E coli. Sasol (LAUS 2016). The results of this study it is concluded that 2,2 -bis[[(2 -hexyl-1 -oxodecyl)oxy]methyl]-1,3 -propanediyl bis(2 -hexyldecanoate), the registered substance, is not mutagenic in the Salmonella typhimurium strains TA97a, TA98, TA100, TA102 and TA1535 in the absence and presence of metabolic activation under the experimental conditions in this study.
A mouse lymphoma assay for 85186 -89 -6 (now 85566 -29 -6) under OECD 476 guidelines and a chromosal aberration test to human lymphocytes for 403507 -18 -6 under OECD 473 guidelines were negative.

DURATION
- Preincubation period: 20 min (only in the second experiment)
- Exposure duration: 48 h
NUMBER OF REPLICATIONS: 3
DETERMINATION OF CYTOTOXICITY:
- Method: In the pre-experiment: determination of titre (the test item was considered non-toxic, if the quotient titre/toxicity is below 2), in the main experiments: evaluation of background lawn, reduction in number of revertants in comparison to negativ/solvents control
OTHER EXAMINATIONS:
- Visual counting of mutant colonies, a spreadsheet software (Microsoft Excel) was used to calculate mean values and standard deviations.
- Quality control of bacterial strains: genotype confirmation for each batch of bacteria before stock culture preparation: All bacterial strains were tested for histidine requirement, ampicillin resistence, crystal violet sensitivity, UV sensitivity and spontaneous revertants, furthermore the following examinations were performed: determination of titre, toxicity control, sterility control and positive control.
- Visual inspection of precipitation: Plates were checked for precipitation of test item at the end of the incubation - Evaluation criteria:
- The colonies were counted visually, the numbers were recorded. A spreadsheet software (Microsoft Excel®) was used to calculate mean values and standard deviations of each treatment, solvent control and positive control. The increase factor f(I) of revertant induction (mean revertants divided by mean spontaneous revertants) and the absolute number of revertants (revertants less mean spontaneous revertants) were also calculated.
A substance is considered to have mutagenic potential, if a reproducible increase of revertant colonies per plate in at least one strain exceeding an increase factor of 2 (in tester strains TA 97a, TA98, TA100 and TA102) and an increase factor of 3 (in tester strain TA1535) as compared to the reversion rate of the solvent control can be observed. A concentration-related increase over the range tested can also be taken as a sign of mutagenic activity. - Statistics:

COMPARISON WITH HISTORICAL CONTROL DATA: Nearly all determined values for the spontaneous revertants of the negative controls were in the normal range of the test laboratory, differences were only marginal and no critical impact on the outcome of the study was expected. All positive control showed mutagenic effects with and without metabolic activation and all were within the historical control data ranges.
For the solvent control THF, no historical data are available. This can be seen as uncritical, because the values of the spontaneous revertants are in normal range of the data for the other solvent controls (demin. water and DMSO) in the test facility. - Conclusions:
- Based on the results of this study it is concluded that the test item is not mutagenic in the Salmonella typhimurium test strains TA97a, TA98, TA100, TA102 and TA1535 in the absence and presence of metabolic activation under the experimental conditions in the present study.
- Executive summary:
The study procedures described in this report were based on the most recent OECD and EC guidelines and performed under the principles of GLP. The test item 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) was tested in the Salmonella typhimurium reverse mutation assay with five strains of Salmonella typhimurium (TA97a, TA98, TA100, TA102 and TA1535). The test was performed in three experiments in the presence and absence of S9-mix (rat liver S9-mix induced by Aroclor 1254). In the first experiment, 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) (dissolved in THF) was tested up to nominal concentrations of 5000 μg/plate in the absence and presence of S9-mix (0.74 % final concentration in the treatment) in the strains TA97a, TA98, TA100, TA102 and TA1535 using the plate incorporation method. 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) showed no precipitates on the plates at any of the concentrations. The bacterial background lawn was not reduced at any of the concentrations and no relevant decrease in the number of revertants was observed in all bacteria strains. The test item 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) showed no signs of toxicity towards the bacteria strains in both the absence and presence of metabolic activation. The results of this experiment showed that none of the tested concentrations showed a significant increase in the number of revertants in all tested strains, in the presence and the absence of metabolic activation. On the base of the first experiment, 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) was tested up to nominal concentrations of 5000 μg/plate in the absence and presence of S9-mix (0.74% final concentration in the treatment) in all bacteria strain using the pre-incubation method. 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) showed no precipitates on the plates at any of the concentrations. The bacterial background lawn was not reduced at any of the concentrations and no relevant decrease in the number of revertants was observed in all bacteria strains. The test item 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) showed no signs of toxicity towards the bacteria strains in both the absence and presence of metabolic activation. The results of this experiments showed that the test item 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) caused no increase in the number of revertants in all bacteria strains compared to the solvent control, in both the absence and presence of metabolic activation. The test item 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) did not induce a dose-related increase in the number of revertants colonies in all strains, in the presence and absence of metabolic activation.
Based on the results of this study it is concluded that 2,2-bis[[(2-hexyl-1-oxodecyl)oxy]methyl]-1,3-propanediyl bis(2-hexyldecanoate) is not mutagenic in the Salmonella typhimurium strains TA97a, TA98, TA100, TA102 and TA1535 in the absence and presence of metabolic activation under the experimental conditions in this study.

Additional information
The registered substance is substantially similar to CAS 85566 -29 -6 (formerly 85186 -89 -6), and CAS 403507 -18-6 which are part of the polyol ester category. In summary, several studies are available to assess the mutagenic potential in bacteria within the polyol esters category all providing negative results. Furthermore, no cytogenicity in mammalian cells in-vitro and no mutagenicity in mammalian cells in-vitro were observed with other members of the polyol esters category.
In conclusion, all available and reliable in vitro and in vivo studies conducted with polyol esters category members revealed no effects on genetic toxicity.
Short description of key category
information:
In none of these studies mutagenicity in bacteria could be observed.
In none of these studies clastogenic effects in mammalian cells could be
observed.
In none of these studies mutagenicity in mammalian cells could be
observed.
Endpoint Conclusion: No adverse effect observed (negative)
The category justification is in IUCLID section 13.
Justification for classification or non-classification
According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met. Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint".Since the category concept is applied to the polyol esters, data gaps will be filled by interpolation, as part of a read across approach from a representative category member(s) to avoid unnecessary animal testing. Additionally, once the category concept is applied, substances will be classified and labelled on this basis. Therefore, based on the group concept, all available data on genetic toxicity do not meet the classification criteria according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
