Additional information

Justification for classification or non-classification

Dibasic lead stearate does not require classification for explosiveness.

The study does not need to be conducted because there are no chemical groups directly associated with explosive properties.

The experimental determination of the explosivity of a compound is not required, if available thermodynamic data (reaction enthalpies) and/or the absence of certain reactive groups (Bretherick, 1990) in the structural formula indicate that the substance will not decompose violently under formation of gases or release of energy and thus does not pose a risk for explosivity.

The absence of reactive groups in the structural formula and the oxygen balance being less than -200 (stearate moiety) indicate that the substance will not decompose violently under formation of gases or release of energy (and thus does not pose a risk for explosivity). Thus, testing does not need to be conducted and a negative result can be predicted.

Since this analysis has provided adequate justification to assume that stearic acid lacks explosive properties, and given that the lead cations also present in this compound are considered to be “inert” in the context of explosivity, the substance dioxobis(stearato) trileadis therefore also considered to be void of any explosive properties.

Further, it is noted that during long term industrial use of the substance, no observations relating to explosiveness have been made, and thesubstance is not classified for explosive properties according to UN transport regulations.

The study is therefore waived in accordance with REACH Annex VII, Section 7.11, Column 2.
