Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Deviations:
no
Qualifier:
according to guideline
Guideline:
other: DIN 51006
Deviations:
no
GLP compliance:
no
Type of method:
other: thermal gravimetric analysis (TGA)
Key result
Decomposition:
yes
Decomp. temp.:
> 240 °C
Remarks on result:
not determinable
Remarks:
A boiling point was not observed, but decomposition of the test substance was observed during a thermogravimetric analysis. The pressure during the test was not reported, however an atmospheric pressure can be assumed.

Differential scanning calorimetry (DSC) as well as thermo gravimetry (TGA) resulted in decomposition of the test sample above 240 °C before melting or boiling.

Residue of thermogravimetric analysis: 19.4%.

Conclusions:
Zinc dipropionate starts to decompose at a temperature > 240 °C. As the substance decomposes at > 240 °C before melting or boiling, neither a melting nor a boiling point could be determined.

Description of key information

Zinc dipropionate starts to decompose at a temperature > 240 °C. As the substance decomposes at > 240 °C before boiling, no boiling point could be determined.

Key value for chemical safety assessment

Additional information

Differential scanning calorimetry (DSC); according to regulation (EC) No. 440/2008, A.1 and DIN 51004 and thermo gravimetry (TGA), according to DIN 51006.
