Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The water solubility of N-(1,3-dimethylbutyl)-N'-phenylbenzene-1,4-diamine (Vulkanox 4020) is approx. 1 mg/L at 50°C (Bayer AG, 1997)
In another test the water solubility of N-(1,3-dimethylbutyl)-N'-phenylbenzene-1,4-diamine (Santoflex 13) is 1.1 mg/L at ambient temperature.
(Monsanto, 1978)
-Because of the test substance DUSANTOX 6PPD is not stable in water, it is not possible to determine its water solubility. (Duslo, 2008)
Key value for chemical safety assessment
- Water solubility:
- 1 mg/L
- at the temperature of:
- 50 °C
Additional information
This result is of theoretical interest as the substance hydrolyses rapidly with a half life of about 8 hours.
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.
