- Conclusions:
- Iron oxide isostearate did not melt under the conditions of the test.
- Executive summary:
Iron oxide isostearate was tested according to OECD Guideline 102 under GLP-compliance.
The test item did not melt under the conditions of the test.
Melting point > 400 °C.
Reference
In the preliminary test, there was no endothermic heat effect observed from which melting point or boiling point could be deduced. An exothermic heat effect was detected starting at about 130°C. After the experiment, the sample was black and agglutinated but not molten.
To confirm the result, two further DSC runs were performed. No endothermic reaction could be observed. Starting at about 120°C an exothermic reaction was observed. After both experiments, the sample had lost about 35% of its mass and the sample was black and agglutinated.
Description of key information
Melting point is higher than 400°C.
Key value for chemical safety assessment
Additional information
A GLP experimental study, according to OECD guideline 102 and scored as Klimisch 1, is selected as a key study, giving a melting point > 400°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
