Applicant's summary and conclusion
- Conclusions:
- The study procedures described in this report were based on the most recent OECD and EC guidelines.
Based on the results of this study it is concluded that 3,3'-Oxybis-1-propanol 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. - Executive summary:
The test item 3,3'-Oxybis-1-propanol 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 two experiments in the presence and absence of metabolic activation, with +S9 standing for presence of metabolic activation, and –S9 standing for absence of metabolic activation.
Experiment 1:
In the first experiment, the test item (dissolved in demin. water) was tested up to concen-trations of 5000 µg/plate in the absence and presence of S9-mix in the strains TA97a, TA98, TA100, TA102 and TA1535 using the plate incorporation method.
The test item 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 rele-vant decrease in the number of revertants was observed in all bacteria strains. The test item 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.
Experiment 2:
Based on the results of the first experiment, the test item was tested up to concentrations of 5000 µg/plate in the absence and presence of S9-mix in all bacteria strains using the pre-incubation method.
The test item 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 rele-vant decrease in the number of revertants was observed in all bacteria strains. The test item 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 caused no increase in the num-ber of revertants in all bacteria strains compared to the solvent control, in both the ab-sence and presence of metabolic activation. The test item did not induce a dose-related increase in the number of revertants colonies in all strains, in the presence and absence of metabolic activation.
