Applicant's summary and conclusion

Conclusions:
Henry's law constant was calculated to be 17.2 Pa.m3/mol at 25 °C based on experimental water solubility and experimental vapour pressures for the C12-C18 AAAO substance. The value indicates that a low rate of volatilisation from surface water is expected.
