Constant vapor pressure emulsions evaporation: Linalool/water stabilized by Laureth 4

Evaporation paths were calculated in the title system using the relevant part of its published phase diagram and the assumption of equilibrium between vapor and liquids. The vapor pressure of linalool was reduced while the emulsion resided in the two-phase region but remained constant within the three-phase range. The duration of the time for constant vapor pressure depended on the relative humidity (RH) to a surprising degree.
