Description of key information

Lead tetraacetate is not oxidizing with regard to EC440/2008 based on read across from Lead (2,4) oxide.

Key value for chemical safety assessment

Oxidising properties:

Additional information

Lead tetraacetate is a selective oxidiser used for certain chemical reactions, e.g. the cleavage of glycols to form ketones (Crigee reaction). It therefore had been labelled as an oxidizer in the past in Safety Data Sheets without an underlying serious assessment of the classification requirements.

Testing of oxidising properties according to the classification specification and test guidance A.17 of EC440 -2008

was conducted with the read-across substance read lead (lead (2,4) oxide or lead tetraoxide, CAS 1314 -41 -6 and revealed that this lead compound does not exhibit oxidising properties. Since read lead contains lead at the same oxidation stage than in the substance, and also since the substance decomposes to lead tetroxide above 140°C, it is not expected that the substance will deliver more oxygen than red lead to support combustion. Additionally, in practical terms, the acetic acid vapour which is released together with oxygen at higher temperatures, will dilute the oxidising effect. Therefore there is no scientific reason to expect the substance to be more vigorously oxidising than red lead.

Based on the read-across, it is concluded that lead tetraacetate does not exhibit oxidising properties that can be detected in tests equivalent to A.17 of EC440 -2008. .
