Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Acute studies:
The 96 h LC50 of benzyltoluene to zebra fish is concluded to be > 267 µg/L, under the conditions of the test. The no observed effect concentration (NOEC) is concluded at the highest achieved concentration in test water NOEC= 267 µg/L.
Benzyltoluene is not toxic to daphnia at the maximum achivable concentration in the test media. No adverse effect was observed and so, EC50 > 0.24 mg/L after 48h exposure.
In an OECD 201 TG compliant study performed under GLP, benzyltoluene did not affect algal growth rate over a 72 h period, EC50>176 µg/L.
No effect was observed until the maximum achievable concentration in the test media.
No inhibition of respiration of Pseudomonas putida up to 0.99 g/L.
Chronic studies:
The overall NOEC according to the OECD 210 TG of Benzyltoluene for the early life stages of fish is 0.064 mg/L and the overall LOEC is 0.21 mg/L.
The effects of a chronic exposure to the test item on the reproduction of Daphnia magna was investigated according the OECD 211 TG. The evaluation was based on the time-weighted mean concentrations. Under the experimental conditions and after 21 days, the EC10 value estimated for the most sensitive endpoint cumulative number of offspring was 0.043 mg test item/L.
In an OECD 201 TG compliant study performed under GLP, benzyltoluene did not affect algal growth rate over a 72 h period at the maximum achievable solubility.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
