Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Effect levels
Sex:
male
Dose descriptor:
LD50
Effect level:
> 5 000 mg/kg bw
95% CL:
9.63 - 20.77
Remarks on result:
other: LD50 quoted as 14.1 mL/kg (12267 mg/kg using density of 0.87)

Any other information on results incl. tables

LD50 quoted as 14.1 mL/kg (9.63 -20.77)

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
LD50 value of 14.1 mL/kg (9.63-20.77), corresponding to 12267 g/kg (8.38-18.07).
Executive summary:

Acute dermal toxicity in the rabbit was found to be low (LD50 >5000 mg/kg). Toluene does not warrant classification under GHS / CLP.
