Any other information on results incl. tables

The test item showed an endothermic signal in the temperature range of approx. 50 – 140 °C that can be assigned to the boiling of the test item.

For the correction of the boiling temperature to standard pressure the test item was assigned to chemical group 6 (e.g. Water). According to appendix 8.2 a correction value φ = 5.65 was used for the temperature of 100 °C.

The lowest measured onset temperature was corrected to the standard pressure to be 98.74 °C and the highest onset temperatureto be 102.49 °C. As the corrected onset temperatures inboth tests deviate more than 0.5 K from their mean value of 100.62 °C, the test item has a boiling range of 99 – 101 °C.

No further thermal effects were observed up to the maximum test temperature of 500 °C.

Applicant's summary and conclusion

Conclusions:
The test item Phosphoric acid, C16-18-branched and linear alkyl esters, potassium salts has a boiling range of 99 – 101 °C corrected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
