Additional information

Benzyltoluene shows a low solubility in water (< 0.1 mg/L). No acute toxicity is observed up to the solubility limit (slightly different from a test to another depending on experimental conditions and medium composition). Therefore no PNECaqua could be derived from these data. No PNECsediment or soil could consequently be calculated through the equilibrium partitioning method. A PNECsediment is proposed, based on an acute toxicity on a marine sediment reworker, as a worst case.

Conclusion on classification

No toxicity related classification is proposed due to lack of observed effects in acute tests. However, given the log Kow > 4 and a lack of ready biodegradability, according to CLP regulation EC 1272/2008 criteria, the substance is classified as "Aquatic chronic category 4" (H413).
