Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value determined at GLP accredited laboratory study in accordance with OECD Guideline 222 and ISO/FDIS 11268-2.
The key value is the lowest NOEC reported for reproduction.
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 62.5 mg/kg soil dw
Additional information
There was no treatment-related mortality of adult earthworms exposed to 4-(1-methyl-1-phenylethyl)-N-[4-(1-methyl-1-phenylethyl)phenyl]aniline at 62.5, 125, 250, 500, and 1000 mg/kg dry soil for 28 days. Based on body weight and survival data of adult earthworms, the no observed effect concentration (NOEC) was determined to be 1000 mg/kg dry soil, the highest concentration tested. There were no reductions of 50% or greater for the numbers of juveniles produced in the treatment groups in comparison to the negative control group, therefore the EC50 for reproduction was greater than 1000 mg/kg dry soil, the highest concentration tested. The NOEC was 62.5 mg/kg dry soil and the LOEC was 125 mg/kg dry soil, based on the numbers of juveniles produced.
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.
