Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Oleic acid-based TEA-Esterquat at 20°C and 1013 hPa is highly viscous liquid with air bubbles enclosed, indicating that the liquid is fairly above the solidifying range. The melting/Freezing range is < 20°C.

Conclusions:
The melting/freezing range of oleic acid-based TEA-Esterquat is < 20°C.
Executive summary:

Oleic acid-based TEA-Esterquat at 20°C and 1013 hPa is highly viscous liquid with air bubbles enclosed, indicating that the liquid is fairly above the solidifying range. The melting/freezing range is < 20°C.

Description of key information

melting/freezing range: 4 - 10 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
4 °C

Additional information

Oleic acid-based TEA-Esterquat at 20°C and 1013 hPa is highly viscous liquid with air bubbles enclosed. Several attempts to remove these air bubbles failed. This indicates that the liquid is fairly above the solidifying range. The melting/freezing range is 4 - 10 °C.
