HENRY'S LAW CONSTANT (HLC) The HLC of C20/22 ATQ can be calculated from
vapour pressure (IUCLID Section 4.6) water solubility (IUCLID Section
4.8). The Exposure assessment tool EUSES 2.1 recalculates the HLC of
3.6*E-3 Pa*m3*mol-1at 25 degree C to 1.7*E-3 Pa*m3*mol-1at the
environmental temperature of 12 degree C. The dimensionless air-water
partitioning coefficient is calculated to 7.4*E-7 m3/m3. The HLC shows
that volatilisation of C20/22 ATQ from aqueous solutions is very low.
