Mini-emulsions have been formed in quaternary systems water/hexanol/sodium dodecyl sulfate/decane by dilution of a microemulsion with an excess of water. We have investigated systematically the effect of composition variables in the droplet size and Ostwald Ripening rate. This droplet size has been investigated by using dynamic light scattering of samples submitted to further dilution in water. According to the dynamic light scattering results, the initial droplet size depends on the initial microemulsion water content, the larger the initial water concentration, the smaller the initial droplet size. This is probably related to the structure of the initial phase. The rate of Ostwald Ripening depends on the final surfactant concentration as expected for differences in interfacial tension. At high surfactant and dispersed phase contents, instability due to flocculation has been observed. Other experiments in which a fifth component (a more hydrophobic oil) was added to slow down Ostwald Ripening showed an initial droplet size increasing comparable to the systems without additive but after a relatively long time of approximately 2 h, a decrease was observed.

通过微乳液稀释形成的微乳液的形成和性质。

通过用过量的水稀释微乳液，在季体系水/己醇/十二烷基硫酸钠/癸烷中形成了微乳液。我们已经系统地研究了组成变量对液滴尺寸和奥斯特瓦尔德熟化速率的影响。通过使用在水中进一步稀释的样品进行动态光散射研究了这种液滴的大小。根据动态光散射结果，初始液滴尺寸取决于初始微乳液水含量，初始水浓度越大，初始液滴尺寸越小。这可能与初始阶段的结构有关。奥斯特瓦尔德熟化速率取决于最终表面活性剂浓度，如界面张力差异所预期的那样。在高表面活性剂和分散相含量的情况下，已经观察到由于絮凝引起的不稳定性。其他实验中，加入第五种成分（疏水性更高的油）以减慢奥斯特瓦尔德熟化，与没有添加添加剂的系统相比，初始液滴尺寸增加，但经过大约2小时的较长时间后，观察到减小。
