In an in vitro bacterial mutation assay, alpha C18 product was not mutagenic to five strains of Salmonella typhimurium or two strains of Escherichia coli in the presence or absence of metabolic activation.- Executive summary:
In a reverse gene mutation assay in bacteria, five strains of Salmonella typhimurium (TA98, TA100, TA1535, TA1537, and TA1538) and 2 strains of Escherichia coli (WP2 and WP2uvrA) were exposed to alpha C18 product in acetone at concentrations of 0, 0.2, 2, 20, 200, or 2000 µg/plate in the presence and absence of mammalian metabolic activation using the plate-incorporation method. No increase in reverse mutation rate was noted in either assay in the presence or absence of metabolic activation. A preliminary study to assess bacterial cytotoxicity to determine appropriate doses was not performed.
This study received a Klimisch score of 2 and is classified as reliable with restrictions because no GLP statement was included and although the study adhered to most of the principles outlined in OECD 471, a few study deficiencies were noted.
No tables are included because all results were negative.
