The evaporation paths for constant fragrance vapour pressure were calculated in a model emulsion system of water, surfactant, and linalool It was found that the water content of the liquid crystal had a moderate effect on the time during which the fragrance vapour pressure was constant, significantly less of a consequence than the fraction of surfactant in the oil phase in equilibrium with the aqueous and liquid crystal phases The results will serve as a guidance for the formulation of optimal fragrance emulsions for the mass market
