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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Waiving of study:
In accordance with REACH Regulation 1907/2006, Annex VIII, Column 2, an adsoprtion/desporption screening test does not need to be conducted because, based on the physicochemical properties of the substance, it can be expected to have a low potential for adsorption (the octanol-water partition coefficient is low at 2.5). In addition, the substance is not hydrolytically stable.
Key value for chemical safety assessment
- Koc at 20 °C:
- 10
Additional information
No data was available for MHHPA. Instead a read across approach was used, assessing data of 4-MHHPA. For 4-MHHPA, a Koc was estimated by QSAR calculation (US EPA EPIWIN, v4.0). The Koc was calculated to be 10 L/kg and a logKoc of 1.0.
[LogKoc: 1.0]
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.
