Description of key information

-3 to 53°C at ca. 1013 hPa (OECD 102, DSC)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
47.9 °C

Additional information

The melting point of the substance Octadecan-1-ol, ethoxylated, < 2.5 EO (CAS 9005-00-9) was determined by Differential Scanning Calorimetry according to OECD Guideline 102. During heating, various endothermic effects were observed between -3 and 53 °C. All of these effects were attributed to the melting of th crystalline parts of the substance. The biggest effect was noticed at 47.9 °C, which will be used as key value for chemical safety assessment. During cooling down, a crystallization effect was observed at 43 °C.
