Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- -2 °C
- Atm. press.:
- 1 005.4 hPa
- Remarks on result:
- other: 85% aqueous solution; Melting point similar to that of water.
Any other information on results incl. tables
During the cooling phase, at a temperature of approx. -15 °C an exothermic effect was observed, which can be assigned to the freezing of the test item.
During the heating phase an endothermic effect was observed in the temperature range of -5 to 15 °C, which can be assigned to the melting of the test item. As the onset temperatures in both tests deviate by less than 0.5 K from their mean value of -0.24 °C, the test item has a melting point of -0.2 °C.
Applicant's summary and conclusion
- Conclusions:
- The test item Phosphoric acid, C16-18-branched and linear alkyl esters, potassium salts has a melting point of -0.2 °C at atmospheric pressure (1005 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
