The mutagenicity of magnesium potassium fluoride silicate
(Mg2.7K0.7Si4O10F2) was evaluated in a bacterial reverse mutation (Ames)
assay, conducted according to OECD Test Guideline 471 and to GLP, using Salmonella
typhimurium strains TA98, TA100, TA1535 and TA1537, and Escherichia
coli strain WP2uvrA. The substance was tested by
plate-incorporation up to the limit concentration of 5000 μg/plate, in
the presence and absence of a rat liver-derived metabolic activation
fraction (S9). There were no increases in revertant colony numbers over
controls with any tested strains at any tested concentrations. Magnesium
potassium fluoride silicate (Mg2.7K0.7Si4O10F2) was therefore concluded
to be non-mutagenic.
