Any other information on results incl. tables
On heating the sample minimal signs of condensation were observed at 120 ºC, there were no signs of reflux and no temperature rise was seen at the condenser.
At 205 ºC the sample was observed to be “smoking”, and the temperature at the condenser increased to 42 ºC. The sample was observed to be darker in colour.
At 260 ºC the signs of condensation remained minimal and the sample was observed to be much darker in colour.
Conclusion
The initial signs of condensation observed at 120 ºC were attributed to residual water from the preparation of the sample. At temperatures above 200 ºC the sample was observed to be decomposing. It can therefore be concluded that zinc neodecanoate decomposes before the boiling point is reached.
The sample was not observed to ignite during the test, therefore it can be concluded that the autoflammability temperature of zinc neodecanoate is greater than 260 ºC
Applicant's summary and conclusion
- Conclusions:
- The sample was not observed to ignite during the test, therefore it can be concluded that the autoflammability temperature of the test item is greater than 260 ºC.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
