Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
oxidising liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is pyrophoric
Conclusions:
Determination of oxidizing properties is not required for zinc alkyls
because the substance is highly flammable and even spontaneously
ignites on contact to air at room temperature.

Description of key information

The endpoint is waived due to pyrophoric properties.

Key value for chemical safety assessment

Additional information

According to the Annex VII Standard Information Requirements for REACH, determination of oxidizing properties is required. Column 2 - specific rules for adaption from column 1 - states that oxidizing properties determination does not need to be conducted in case the substance is highly flammable. 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).
