TA1537: Experiment 1 = 1.3; Experiment 2 = 1.5
DURATION
- Preincubation period:
- Exposure duration:
- Expression time (cells in growth medium):
- Selection time (if incubation with a selection agent):
- Fixation time (start of exposure up to fixation or harvest of cells): - Evaluation criteria:
- There are several criteria for determining a positive result.
Any, one, or all of the following can be used to determine the overall result of the study:
1. A dose-related increase in mutant frequency over the dose range tested (De Serres and Shelby, 1979).
2. A reproducible increase at one or more concentrations.
3. Biological relevance against in-house historical control ranges.
4. Statistical analysis of data as determined by UKEMS (Mahon et al., 1989).
5. Fold increase greater than two times the concurrent solvent control for any tester strain (especially if accompanied by an out-of-historical range response (Cariello and Piegorsch, 1996)).
A test item will be considered non-mutagenic (negative) in the test system if the above criteria are not met. - Statistics:
- Statistical significance was confirmed by using Dunnetts Regression Analysis (* = p < 0.05) for those values that indicate statistically significant increases in the frequency of revertant colonies compared to the concurrent solvent control.

Applicant's summary and conclusion
- Conclusions:
- 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-coco acyl derivs., hydroxides, inner salts was considered to be non-mutagenic under the conditions of this test.
- Executive summary:
A GLP compliant bacterial reverse mutation test was performed on the substance in accordance with OECD Test Guideline 471.
Several strains of bacteria were treated with the test item using both Ames plate incoporation and pre-incubation methods at doses ranging from 0.5 to 5000 µg/plate, with and without S9 -mix.
Sterile distilled water was used as the vehicle as the test item is soluble in water.
There were no increases in the frequency of revertant colonies observed for any of the bacterial strains, at any of the doses, with or without metabolic activation in the plate incorporation or pre-incubation experiments. All controls were valid.
Under the conditions of this test, 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-coco acyl derivs., hydroxides, inner salts was found to be non-mutagenic.
