Results
Thermal Stability (DSC)
The test item showed two endothermic effects in the temperature ranges of 110 °C to 160 °C and 220 °C to 330 °C, respectively. An exothermic was observed in the temperature range of 350 °C to 400 °C with a mean decomposition energy of -100 J/g.

* Different from the convention applied in the thermograms, energies of exothermic effects are presented as negative values and energies of endothermic effects as positive values.
Determination of the SADT in the adiabatic heat-storage test
Due to the fact that the overall decomposition energy of the exothermic effects in the DSC measurments was < -300 J/g, it was not necessary to perform the test for the determination of the SADT.
Conclusion
Thermal Stability OECD 113: The test item DMPSA-K2 in closed glasscrucibles showed two endothermic effects in the temperature ranges of 110 °C to 160 °C and 220 °C to 330 °C, respectively. An exothermic was observed in the temperature range of 350 °C to 400 °C with a mean decomposition energy of -100 J/g.
Description of key information
Decomposition between 350 °C and 400 °C with a decomposition energy of -100 J/g

Justification for classification or non-classification
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.
