    • Shampoo compositions comprise (a) from about 5 % to about 50 % of one or more detersive surfactants, by weight of the shampoo composition; (b) a dispersed gel network phase comprising, by weight of the shampoo composition, (i) at least about 0.05 % of one or more fatty alcohols; (ii) at least about 0.01 % of one or more secondary surfactants; and (iii) water; and (c) at least about 20 % of an aqueous carrier, by weight of the shampoo composition; and, wherein the dispersed gel network phase has a melt transition temperature of at least about 38 °C. A process for preparing a shampoo composition comprises the steps of: (a) combining a fatty alcohol, a secondary surfactant, and water at a temperature sufficient to allow partitioning of the secondary surfactant and the water into the fatty alcohol to form a pre-mix; (b) cooling the pre-mix below the chain melt temperature of the fatty alcohol to form a gel network; (c) adding the gel network to one or more detersive surfactants and an aqueous carrier to form a shampoo composition which comprises a dispersed gel network phase having a melt transition temperature of at least about 38 °C.
    • 洗发剂组合物包含(a)按洗发剂组合物的重量计约5%至约50%的一种或多种去污表面活性剂; (b)分散的凝胶网络相,其包含按重量计的洗发剂组合物,(i)至少约0.05%的一种或多种脂肪醇; (ii)至少约0.01%的一种或多种第二表面活性剂; 和(iii)水; 和(c)以洗发剂组合物的重量计至少约20%的水性载体; 并且其中分散的凝胶网络相具有至少约38℃的熔融转变温度。 制备洗发剂组合物的方法包括以下步骤:(a)在足以使第二表面活性剂和水分分解成脂肪醇以形成预混物的温度下将脂肪醇,第二表面活性剂和水混合 ; (b)将预混物冷却至低于脂肪醇的链熔体温度以形成凝胶网络; (c)将凝胶网络添加到一种或多种去污表面活性剂和水性载体中以形成洗发剂组合物,其包含具有至少约38℃的熔融转变温度的分散的凝胶网络相。
