Results
To determine the melting behaviour (three independent single measurements), the test item was measured by DSC between -90 °C and 50 °C with a heating / cooling rate of 10 K/min in 2 cycles. For the measurement a capsulated crucible was used.
The test item Propyl oleate shows a melting area of crystalline subcomponents between -48 °C and -15 °C according to the definition in the OECD Guideline 102 (mean value from repeat determination).
-48 °C to -15 °C (from first measurement)
-48 °C to -15 °C (from second measurement)
-48 °C to -15 °C (from third measurement)
The cooling run shows a crystallization.
Description of key information
