Sodium thioglycolate is usually used as an analytical reagent As well as in bacteriology to the preparation of thioglycolate media. Sodium thioglycolate was nominated with the nationwide Cancer Institute for toxicology research as a result of its superior output volume and popular occupational and client exposure to thioglycolic acid and its salts and esters, like substantial feminine exposure in individual treatment products. Male and woman F344/N rats and B6C3F1/N mice had been administered sodium thioglycolate (about ninety nine% pure) inside a motor vehicle of ninety five% ethanol:deionized water (1:1) by application to shaved dorsal skin for 16 (rats) or 17 (mice) times or for 3 months. Genetic toxicology reports were performed in Salmonella typhimurium and mouse peripheral blood erythrocytes.
