Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is pyrophoric
- Conclusions:
- Determination of flash point is technically not feasible for zinc alkyls and
won't deliver additional safety / risk information.
Reference
Description of key information
The endpoint is waived: Determination of flash point is technically not feasible for zinc alkyls as they are pyrophoric.
Key value for chemical safety assessment
Additional information
According to the Annex VII Standard Information Requirements for REACH, flash point determination is required. In column 2 - specific rules for adaption from column 1 - no conditions are listed applicable to zinc alkyls that justify exemption from flash point determination. Zinc alkyls are highly reactive both towards oxygen (air) and water as explained below. They are exclusively marketed in liquid state and shipped under UN transport class 4.2 (substances liable to spontaneous combustion / pyrophoric liquids) or at least under class 4.3 (substances which in contact with water emit flammable gases). Determination of flash point is technically not feasible for zinc alkyls and won’t deliver additional safety / risk information.
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.
