- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
This read-across is based on the hypothesis that source and target substances have similar (eco)toxicological properties because
• they share structural similarities with common functional groups: One quaternised ethanolamine moiety, one to three, mainly two ester groups with a typical UVCB distribution with long-chain fatty acids of natural origin. The molecular structure is almost identical.
• they are manufactured from similar resp. identical precursors (triethanolamine, long-chain fatty acids, dimethyl sulphate) under similar conditions. Therefore, common breakdown products via physical and biological processes, which result in structurally similar chemicals are evident
• A constant pattern in the changing of the potency of the properties across the TEA-Esterquats by chain-length and the grade of esterification is not observed, because the fatty acid chain-length distribution is too narrow and similar and the distribution of mono-, di-, and tri-esters is identical. Some variation caused by variation in C=C double bonds may occur and will be discussed at the relevant endpoint.

Additional information
No experimental data are available for the target substance oleic acid-based TEA-Esterquat. However, reliable and relevant data are available for partially unsaturated TEA-Esterquat. The full set of in vitro tests required by REACH Regulation Annexes VII and VIII is covered with the studies. There was no evidence of mutagenic or genotoxic intrinsic properties in any of the performed studies. Additional data from an in vivo mouse micronucleus Test are available, likewise showing no evidence to cause any chromosomal damage in the bone marrow of mice. A justification for read-across is attached to Iuclid section 13.
In vitro data
A reverse bacterial gene mutation assay (Ames-Test, plate incorporation assay) according to OECD Guideline 471(1997) with partially unsaturated TEA-Esterquat was negative up to the limit concentration of 5000 µg/plate with and without mammalian metabolic activation (rat liver S9-mix 10 and 30 %) in S. typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and E. coli WP2 uvrA (pKM101).
Significant bacteriotoxic effects of varying severity were observed, depending on the test strain and the presence of metabolic activation. Generally, bacteriotoxicity was less pronounced in the presence of metabolic activation, especially at concentrations of 30 % S9-mix. Precipitation was observed at 1600 µg/plate and above. The positive controls induced the appropriate responses in the corresponding strains. There was no evidence of induced mutant colonies over background in any of the tester strains in the presence or absence of mammalian metabolic activation.
In a mammalian cell gene mutation assay (HPRT locus) according to OECD guideline 476, Chinese hamster lung fibroblasts (V79) cells cultured in vitro were exposed to partially unsaturated TEA-Esterquat (100 % a.i. of UVCB description) at concentrations up to 200 µg/mL in the absence and up to 1500 µg/mL in the presence of mammalian metabolic activation (rat liver S9).
The concentration range of the main experiments was limited by the solubility of the test item in aqueous medium and by cytotoxic effects. The assay was performed in two independent experiments, using two parallel cultures each. A treatment period of 4 hours was used for all experiments, with the exception of the second experiment with metabolic activation, were a 24 hour treatment period was selected for the cultures. No substantial and reproducible dose dependent increase of the mutation frequency was observed in both experiments. Appropriate reference mutagens, used as positive controls, induced a distinct increase of mutant colonies and, thus, showed the sensitivity of the test system and the activity of the metabolic activation system.
The results of this HPRT assay indicate, that partially unsaturated TEA-Esterquat did not cause a positive response in the non-activated and S9-activated systems and was assessed to be negative under the conditions of this study.
In a mammalian cell cytogenicity assay according to OECD Guideline 473 1997, V79 cell cultures were exposed to partially unsaturated TEA-Esterquat at concentration ranges of 3.1 – 200 µg/mL without metabolic activation and 4.7 – 600 µg/mL in the presence of mammalian metabolic activation.
In experiment I and II, in the absence and the presence of S9 mix, no biological relevant increase in the number of cells carrying structural chromosome aberrations was observed. However, in the presence of S9 mix two significant (p < 0.05) increases were observed, in experiment I at preparation interval 18 hrs after treatment with 37.5 µg/mL (4 % aberrant cells, exclusive gaps), and in experiment II at preparation interval 28 hrs with 300 µg/mL (4.8 % aberrant cells, exclusive gaps). In addition, a dose related increase in the number of cells carrying structural chromosome aberrations was observed in experiment II with metabolic activation.
A confirmatory experiment III was performed to verify these observations. In the repeated experiment in the presence of S9 mix after
4 hrs treatment at a prolonged 28 hrs preparation interval no biologically relevant increase in the number of cells carrying structural chromosome aberrations was observed. Although the aberration rates showed a dose related increase, the values were clearly within the historical control data range of the testing laboratory. Finally, the observations of experiment II in the presence of S9 mix were not confirmed in experiment III and therefore they have to be regarded as biologically insignificant.
In all experiments, no biologically relevant increase in the rate of polyploid metaphases was found.
In conclusion it can be stated that under the experimental conditions reported, the test item did not induce structural or numeric chromosome aberrations as determined by the chromosome aberration test in V79 cells (Chinese hamster cell line) in vitro. The test item is considered to be non-clastogenic in this chromosome aberration test with and without S9 mix when tested up to cytotoxic test item concentrations.
In vivo data
In a mouse bone marrow micronucleus assay according to OECD guideline No. 474, 1983, 6 male and 6 female albino mice (CFW1) per group were treated by oral intubation with partially unsaturated TEA-Esterquat at a dose of 5000 mg/kg bw. Bone marrow cells were harvested at 24, 48 and 72 hours post-treatment.
There were no signs of toxicity as indicated by an enhanced mortality rate. A slight reduction in the ratio of polychromatic to normochromatic erythrocytes were determined in female mice 24 and 48 h after administration, indicating possibly a weak toxic effect to the bone marrow. The partially unsaturated TEA-Esterquat was tested at an adequate dose, based on the results of the range-finding test. The positive control induced the appropriate response.
There was no significant increase in the frequency of micronucleated polychromatic erythrocytes in bone marrow after any treatment time.
There are no data gaps for the endpoint genetic toxicity. No human data are available. However, there is no reason to believe that these results from rat and rabbits would not be applicable to humans.
Similar results were obtained with the source substance MDEA-Esterquat C16-18 and C18 unsatd.: the substance did not show any genotoxic intrinsic properties in the Ames test, mouse lymphoma assay, chromosome aberration study and in vivo bone marrow micronucleus assay and is therefore considered to be nongenotoxic. These data are included into the dossier to demonstrate, that both substances have a similar toxicological profile.
Justification for classification or non-classification
Based on the available data, the substance does not need to be classified for mutagenicity according to regulation (EC) 1272/2008. Thus, no labelling is required.
