Additional information

There is chronic toxicity data on one of the three constituents of this substance. This substance (MEG) is likely to represent the most toxic of the three components based on the acute toxicity information available. QSAR data also suggests that the toxicity decreases with increasing molecular weight and therefore that monoethylene glycol (MEG) is likely to be the most toxic species. The QSAR does not include a specific class covering acetate salts but predicts that the same neutral organics class can be used as an alternative. The QSAR predicts that sodium acetate will be less toxic that MEG, which confirms that the reliable measured data from MEG can be used as a conservative alternative to predict the overall toxicity of the substance. The experimental data on MEG is a 7 day study in Ceriodaphnia, which can be considered a reliable chronic study. Overall, it is clear that all of the components present very low chronic toxicity. The key parameter is based on the available data for MEG.
