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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Summary and conclusions on persistence
Based on biodegradation test data, this substance is not expected to be readily biodegradable. This substance fulfills the screening criterion for persistence and is identified as being potentially persistent.
Summary and conclusions on bioaccumulation
Based on the weight of evidence from read across to structurally similar ZDDP substances with BCF data in fish (from Japanese MITI data, US EPA database, CAESAR database), measured Low Kow data, and QSAR predictions, this substance is expected to have low bioaccumulation potential. This substance does not meet the criteria of concern for bioaccumulation.
Summary and conclusions on toxicity
Based on the available acute and chronic toxicity data in algae, daphnids, and fish for the substance itself and a structurally similar ZDDP substance (EC283-392-8), this substance is considered unlikely to have significant effects on aquatic organisms in short and long term scenarios and data demonstrate that this material does not meet the criterion for toxicity as outlined in ANNEX XIII of Regulation (EC) 1907/2006.
- Likely routes of exposure:
Dermal route: is considered a principal route for occupational exposure.
Inhalation route:the test material has an extremely low vapour pressure (essentially zero), OECD has indicated that inhalation exposure is negligible if the vapour pressure is less than 1 Pa and ECHA guidance places chemicals with less than 0.1 Pa vapour pressure in the low volatility band (OECD 2003; ECHA R15.5). Therefore, under normal use and handling conditions, respiratory absorption of the test material in the form of vapours, gases, or mists is not expected to be relevant or significant,andno predictions on ADME were made.
Oral exposure: oral is not an anticipated route of exposure to workers or the general population.
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.
