    • A surfactant system capable of structuring a non-aqueous liquid composition, wherein the surfactant system comprises at least about 5% of a structuring particle. The surfactant system preferably further comprises a surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric surfactants and mixtures thereof. A well dispersed mixture of a non-aqueous liquid, for example, a nonionic surfactant, and at least about 25%, by weight of the surfactant system results in the mixture having a yield of at least about 2.0 Pa when measured at 20 sec−1 and 25° C. Moreover, the surfactant system should exhibit a peak when measured by SAXS x-ray diffraction, wherein the peak's center is between about the 1.5 to 2.5 v positions on the 2 theta axis. The structuring particles are most preferably structuring particles of sulfate and linear alkyl benzene sulfonate. Also provide is a method of making the structuring particle.
    • 能够构建非水液体组合物的表面活性剂体系,其中表面活性剂体系包含至少约5%的结构化颗粒。 表面活性剂体系优选还包含选自阴离子,非离子,阳离子,两性表面活性剂及其混合物的表面活性剂。 非水性液体(例如非离子表面活性剂)和至少约25重量%的表面活性剂体系的良好分散的混合物导致混合物的产率至少为约2.0Pa,当在20秒 - 1和25℃。此外,当通过SAXS x射线衍射测量时,表面活性剂体系应显示峰值,其中峰的中心在2θ轴上的约1.5至2.5v位置之间。 结构化颗粒最优选是硫酸盐和直链烷基苯磺酸盐的结构化颗粒。 还提供了制造结构化颗粒的方法。
