Additional information
Conclusion on classification
The lowest acute aquatic toxicity result was obtained on fish and gives a 96hLC50 value between 18 and 24 ppm (v/v). Considering that the relative density of the substance is around 1, the 96hLC50 value is expected to be between 18 and 24 mg/L. Therefore, the substance should be considered as harmful to the aquatic organisms tested.
Additionaly, the substance is readily biodegradable and has a low potential for bioaccumulation (i.e. logKow = 0.6 - 1.4). Therefore, the substance is not classified as dangerous for the environment according to European Directive 67/548/EEC and to Regulation (EC) No 1272/2008.
