Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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.
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.
