Any other information on results incl. tables
The test item showed no evaluable vapour pressure curve in the temperature range of 25 to 56°C. Due to this result, the vapour pressures for the temperatures 20, 25 and 50°C are estimated on the basis of the maximum measured vapour pressures.
Applicant's summary and conclusion
- Conclusions:
- The test item Phosphocreatine, sodium salt (CAS no. 922-32-7) showed no evaluable vapour pressure curve in the temperature range of 25 to 56 °C. Due to this result, the vapour pressures are estimated to be < 2.5E-2 for the temperatures 20, 25 and 50°C 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).
- Executive summary:
