Applicant's summary and conclusion

Conclusions:
The vapour pressure of the dried test item Beta-alanine, N-(2-aminoethyl)-N-[2-carboxyethoxy)ethyl]-, N-coco acyl derivs., disodium salts (aq.solution) was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure and OECD Test Guideline 104 (2006) to be 2.9E-3, 3.4E-3 and 7.7E-3, respectively.
