Description of key information

- The melting/freezing temperature of SCP liquor is in the range of <-22 °C to >115 °C.
- Two different methods were used for the determination of the melting temperature, Capillary method and Freezing temperature.
- According to Regulation (EC) No 1907/2006 Annex VII (7.2) Column 2, the study does not need to be conducted below a lower limit of -20 °C.

Key value for chemical safety assessment

Additional information

Due to the physical state of the test substance two different methods were used for the determination of the melting temperature.

Method 1

Capillary method

During the test from 30 °C to 115 °C the test substance was a brown viscous liquid containing undissolved particles. At about 115 °C the test substance boiled over and therefore no exact melting temperature could be determined. The undissolved particles did not melt until 115 °C.

Method 2

Freezing Temperature

During the test from 20 °C to -22 °C the test substance was a brown viscous liquid (suspension). The test substance did not solidify down to -22 °C.

From the experimental results it is concluded, that the melting/freezing temperature of SCP liquor 1 is in the range of <-22 °C to >115 °C.
