Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 935-783-6 | CAS number: -
Toxicity to soil microorganisms
Administrative data
Link to relevant study record(s)
Description of key information
NOEC (28d) = 300 mg/kg soil dw for nitrogen transformation (OECD 216)
Key value for chemical safety assessment
- Long-term EC10 or NOEC for soil microorganisms:
- 300 mg/kg soil dw
Additional information
No studies are available for the toxicity of the reaction mass to soil microorganisms. Therefore, data for one of the four m-cresol components of the reaction mass, 4-chloro-m-cresol (CAS No. 59-50-7), are used as read across. The effect of the substance on soil microorganisms was investigated in one non-GLP study using loamy sand as test substrate.The inhibition of nitrification was tested according to OECD guideline 216. An EC50 (28d) of 555.1 mg/kg soil dw and a NOEC (28d) of 300 mg/kg soil dw are reported. After 100 days of incubation, the EC50 (100d) was determined to be 395.1 mg/kg soil dw.
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.
