The phase diagram water, phenethyl alcohol and laureth 4 was determined and the variation of the vapour pressure of the alcohol was determined during evaporation using gas chromatographic head-space analysis. The phase changes during evaporation were estimated from the phase diagram and compared to the appearance of the emulsion using optical microscopy. The transfer of the fragrance ingredient between different phases during the process was estimated and its measured vapour pressures compared to those calculated from values of earlier determination in different phases in the system. The agreement was good.
水、苯乙醇和月桂醇聚氧乙烯醚 4 的相图已经确定，并使用气相色谱顶空分析在蒸发过程中测定了酒精蒸气压的变化。通过相图估计了蒸发过程中的相变化，并使用光学显微镜观察乳状液的外观。在过程中，估计了香精成分在不同相之间的转移，并将其测量的蒸气压与从系统中不同相的早期测定值计算得出的值进行了比较。结果吻合较好。
