Three emulsions of geranyl acetate (GA)-in-water (W) with identical GA/W ratios and varying surfactant (S), Laureth 4, a commercial C(12)EO (4) compound, fractions were investigated for nature and stability. The emulsions with up to 6% surfactant were W/O, as expected with respect to the solubility of the surfactant in the oil. At 10% surfactant, the aqueous phase became the continuous one and the apparent stability of the emulsion was significantly enhanced. Analysis of the phase diagram and experimental evidence showed the high water content emulsion to be a liquid crystal-in-water emulsion; a kind that did not change even at extreme O/W and LC/W ratios.
研究了三种水包醋酸香叶酯（GA）乳液，其GA/水比例相同，表面活性剂（S）为月桂醇聚醚4（一种商用C(12)EO(4)化合物），含量不同，以探究其性质和稳定性。正如根据表面活性剂在油中的溶解度所预期的那样，表面活性剂含量高达6%的乳液为油包水型。当表面活性剂含量为10%时，水相成为连续相，乳液的表观稳定性显著提高。相图分析和实验证据表明，高含水量乳液为水包液晶乳液；即使在极端的油/水和液晶/水比例下，这种乳液也不会发生变化。
