    • The invention discloses compositions with enhanced squeaky feel, when rinsed in water, defined by a region of a surfactant-cation phase diagram comprising surfactant-cation precipitate and/or surfactant monomer, but substantially no surfactant micelle. The present invention focuses, for example, on the relationship between counter-ion (e.g., cation, preferably salt cation) and surfactant. Specifically, it has been found that enhancing the precipitation of counter-ion-surfactant complex helps reduce surfactant micellar concentration, enhance surface tension and lead to compositions with enhanced “squeaky” feel. The precipitation can in turn be promoted by enhancing surfactant counter-ion interaction, e.g., by increasing sensitivity of surfactant to counter-ion (e.g., by using long chain length hydrophobe group), and/or by preformulating additional counter-ion into the surfactant solution.
    • 本发明公开了当在水中漂洗时具有增强的吱吱声感觉的组合物,其由包含表面活性剂阳离子沉淀物和/或表面活性剂单体但基本上不含表面活性剂胶束的表面活性剂 - 阳离子相图的区域限定。 本发明的重点在于例如抗衡离子(例如阳离子,优选盐阳离子)和表面活性剂之间的关系。 具体地说,已经发现增强抗衡离子表面活性剂复合物的沉淀有助于降低表面活性剂胶束浓度,增强表面张力并导致具有增强的“吱吱”感的组合物。 通过提高表面活性剂的离子相互作用,例如通过增加表面活性剂对抗衡离子的敏感性(例如通过使用长链疏水基团)和/或通过将额外的抗衡离子预先加入到表面活性剂中,可以促进沉淀 解。
