Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
not performed according to GLP
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
Qualifier:
according to guideline
Guideline:
other: DIN 51004
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.:
> 320 °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.

Thermo gravimetry (TGA) resulted in decomposition of the test sample above 320 °C before boiling.

Residue of thermogravimetric analysis: 14.2%.

Conclusions:
Fatty acids, C18-24, zinc salts starts to decompose at a temperature > 320°C. As the substance decomposes at > 320°C before boiling, no boiling point could be determined.

Description of key information

Substance Fatty acids, C18-24, zinc salts starts to decompose at a temperature > 320°C. As the substance decomposes at > 320°C before boiling, no boiling point could be determined.

Key value for chemical safety assessment
