Genotoxicity assessment of sulfosuccinate IO-5, Rokamid MRZ 17, Rokacet RZG7P2 and Roksol TL-7 using bacteria and bone marrow rodent cells.

Three short-term tests were used for evaluation of the genotoxic activity of four surface active agents. These were: Ames, Salmonella reversion assay using 4 tester strains (TA97a, TA98, TA100 and TA102), the micronucleus test int the bone marrow of Balb C mice and in vivo sister chromatid exchange (SCE) analysis in SFIS or Balb C mice. The frequency of micronucleated PCEs did not exceed the control values in mice of both sexes after intraperitoneal administration of all four compounds. Three preparations--Sulfosuccinate IO-5, Rokamid MRZ 17 and Rokacet RZG7P2 produced a negative response in Salmonella strains gene mutation assay and SCE induction test in mouse bone marrow cells. The Roksol TL-7 induced frameshift and base-pair substitution mutations in Salmonella tester strains both with and without S9 (prepared from the liver of rats which had been pretreated with Aroclor 1254). Evidently positive results (more than a twofold increase in the number of revertants per plate) were observed in tester strain S. typhimurium TA97a (with and without S9 metabolic activation) and S. typhimurium TA100 (with S9 metabolic activation) at a dose of 0.2 microliter Roksol TL-7 per plate. Roksol TL-7 caused slight increase in the SCE level in mouse bone marrow cells. A significant increase in SCE frequency was observed at doses of 50, 75 and 100 mg/kg.
