Any other information on results incl. tables
The test item showed no evaluable vapour pressure curve in the temperature range of 20 to 40 °C. Due to this result, the vapour pressures for the temperatures 20, 25 and 50 °C are estimated on the basis of the maximum vapour pressures. The measured vapour pressure values together with the measured temperatures are listed in the table in the next section "overall remarks".
Applicant's summary and conclusion
- Conclusions:
- The test item Disodium beta-glycerophosphat (CAS no. 819-83-0) showed no evaluable vapour pressure curve in the temperature range of 20 to 40 °C. Due to this result, the vapour pressures for the temperatures 20, 25 and 50 °C were estimated on the basis of the maximum measured vapour pressures, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline 104 (2006).
The vapour pressure of the test item was <6.02E-3 Pa at 20°C, 25°C and 50°C. - Executive summary:
