guideline study

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

OECD Guideline 103 (Boiling point/boiling range)

Deviations:

no

Type of method:

differential scanning calorimetry

Key result

Boiling pt.:

> 400 °C

Atm. press.:

1 013 hPa

Decomposition:

yes

Decomp. temp.:

265 °C

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.

In the main test, in the temperature range between 25°C and 400°C, a small endothermic peak was detected at about 265°C, followed by an exothermic reaction. After the experiment the test item was black and carbonized.

Conclusions:

Iron oxide isostearate did not boil under the conditions of the test.

Executive summary:

Iron oxide isostearate was tested according to OECD Guideline 103 under GLP-compliance.

The test item did not boil under the conditions of the test.

Boiling point > 400°C.

Description of key information

Boiling point is higher than 400 °C.

Additional information

 A GLP experimental study, according to OECD guideline 103 and scored as Klimisch 1, is selected as a key study, giving a boiling point > 400 °C.
