Applicant's summary and conclusion
- Conclusions:
- The endpoint for the genetic toxicity in vitro of N-ethyl-N phenyl benzyl amine (92-59-1) was considered to be negative in the presence and absence of metabolic activator in Salmonella typhimurium strains TA97, TA98, TA100, and TA1535 by Preincubation method.
- Executive summary:
In vitro genetic toxicity test for N-ethyl-N phenyl benzyl amine (92-59-1) was performed on Salmonella typhimurium strains TA97, TA98, TA100, and TA1535 by Preincubation method. The test chemical (0.05 ml), Salmonella culture (0.10 ml), and S-9 mix or buffer (0.50 ml) was incubated at 37°C, without shaking, for 20 min. After that histidine-independent (his+) colonies were counted on plates by machine unless there was any precipitate was present which interfered with the count, or the color of the test chemical on the plate reduced the contrast between the colonies and the background agar.The test material was exposed at the concentration of 0.000 ,100.000, 333.000, 1000.000,3333.000,6666.000,10000.000 µg/plate. There are some variations in protocol as the first test of a chemical was without activation and with 10% S-9 in the S-9 mix. If a positive result was obtained the test was repeated.If the tests were negative they were repeated without S-9 and with 30% S-9.Concurrent solvent and positive controls were run with each test. After exposure no mutagenic effect were observed.Therefore N-ethyl-N phenyl benzyl amine (92-59-1) was considered to be non mutagenic in Salmonella typhimurium strains TA97, TA98, TA100, and TA1535in the presence and absence of metabolic activation.
Hence it is not likely to be classified as genetic mutant in vitro.
