Description of key information

The test substance is not classified. No effects were seen in short-term toxicity studies in aquatic organisms. In an acute toxicity study performed on Oncorhynchus mykiss the 96-hour LC50 was determined to be >0.0167 mg/L (geometric mean measured concentration) and the corresponding NOEC was determined to be 0.0617 mg/L. Chemical analysis showed a decline in measured concentrations over the 24 hour renewal period caused by the insolubility and UVCB nature of the compound, and the filtration of media due to potential of micro-globule or micelles passing through filters. The results at 24 and 72 hours were below the LOQ value. The difficulties in maintaining stable and quantifiable concentrations in the acute tests would be exacerbated in longer-term testing and results would therefore be unreliable. The substance is readily biodegradable and is not persistent in the environment. Exposure to the registered substance is considered to be minimal based on the low concentration of the substance in the formulated and finished products. It is therefore considered that further testing is not justified.
