    • Disclosed is a unique vehicle system which provides a desirable rheology to products formulated therewith, enhanced dispersion of actives therein, and improved deposition of actives therefrom. This vehicle system comprises a primary thickening agent which is a nonionic long-chain alkylated water-soluble polymer, and a secondary thickening agent which is a water-insoluble surfactant dispersed in a compatible solvent. Optionally, a rheological aid, which is a chelating agent may be included in the vehicle system. Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle system. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the hair or skin. The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning compositions, because they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.
    • 公开了一种独特的车辆系统,其为其配制的产品提供期望的流变性,增强其中活性物质的分散性,以及改善活性物质的沉积。 该车辆系统包括作为非离子长链烷基化水溶性聚合物的初级增稠剂和分散在相容溶剂中的不溶于水的表面活性剂的二次增稠剂。 任选地,作为螯合剂的流变助剂可以包括在车辆系统中。 此外,任选地,作为高分子量或强离子特性的水溶性聚合物的分散助剂也可以包括在车辆系统中。 这些载体系统可用于化妆品组合物,其用于将活性成分递送至毛发或皮肤。 车辆系统在头发护理组合物中尤其是洗发型头发调理组合物中特别有用,因为它们有效地将毛发调理组分递送到毛发上,而不会将大量的载体材料沉积在毛发上。
