A total of 10 runs were completed for the main sequence. Equilibrium with regard to vapour pressure was assessed to have been reached over the final 9 runs. Thus, the final 9 runs have been used to calculate the definitive vapour pressure value for the test item.

Conclusions:

The vapour pressure of the test item has been determined to be 2.48 x 10-3 Pa at 25 ºC.

Executive summary:

The vapour pressure of TOFA-MA-TETA has been determined to be 0.00248 Pa at 25 °C, using the vapour pressure balance method, designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals.
