Any other information on results incl. tables
There is no significant difference between the number of spontaneaous reversions, the number of reversions obtained in the positive controls (with or without metabolic activation), and the mean of corresponding experimental historic values obtained in the laboratory.
There is no evidence of any increase of number of revertant colonies in the presence of the test substance (5000, 1000, 500, 100 and 50 µg) with or without metabolic activation for bacterial strains in Salmonella typhimurium TA1535, TA97a, TA98, TA100 and Escherichia coli WP2(uvrA).
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
The test substance does not indice reverse mutation on four salmonella typhimurium strains and one Escherichia coli strain according to the OECD guideline n°471 . - Executive summary:
Assessment of mutagenic activity of squalane was conduced on "Salmonella typhimurium his-" and "Escherichia coli WP2(uvrA)" strains according to the OECD guideline n°471.
There is no significant difference between the number of spontaneaous reversions, the number of reversions obtained in the positive controls (with or without metabolica cativation), and the mean of corresponding experimental historic values obtained in the laboratory.
There is no evidence of any increase of number of revertant colonies in the presence of the test substance (5000, 1000, 500, 100 and 50 µg) with or without metabolic activation for bacterial strains in Salmonella typhimurium TA1535, TA97a, TA98, TA100 and Escherichia coli WP2(uvrA).
