    • A composition comprising, 1-99%wt of surfactant and at least one micro-particle having a diameter of 100nm-2mm, said micro-particle comprising: i) a core comprising a hydrophobic benefit agent (preferably a perfume or a dye), and, ii) a shell comprising an uncharged hydrophobically-modified, water-soluble film-forming polymer (preferably a modified PVOH), whereby the film remains substantially intact in the presence of surfactant but dissolves when the concentration of surfactant is reduced, thereby releasing the benefit agent. The invention provides a process for treatment of surfaces comprising the step of contacting a composition according to the invention with fabric, hair, or living tissue. The invention also provides a method for preparing compositions according to claims 1-13 which comprises the steps of: a) providing an aqueous solution of uncharged, hydrophobically-modified, film forming polymer having a hydrophobic benefit agent dispersed therein, b) forming a layer of the uncharged, hydrophobically-modified, film forming polymer around the dispersed hydrophobic benefit agent, and c) stabilizing said layer with surfactant.
    • 一种组合物,其包含1-99重量%的表面活性剂和至少一个直径为100nm-2mm的微粒子,所述微粒子包括:i)包含疏水有益剂(优选香料或染料)的核心, 和ii)包含不带电荷的疏水改性的水溶性成膜聚合物(优选改性PVOH)的壳,由此在表面活性剂存在下该膜保持基本完整,但当表面活性剂的浓度降低时溶解​​,从而释放 利益代理人。 本发明提供了一种用于处理表面的方法,包括使根据本发明的组合物与织物,毛发或活组织接触的步骤。 本发明还提供了一种制备根据权利要求1-13的组合物的方法,其包括以下步骤:a)提供其中分散有疏水性有益剂的不带电荷的疏水改性的成膜聚合物的水溶液,b)形成层 在分散的疏水有益剂周围的不带电的,疏水改性的成膜聚合物,和c)用表面活性剂稳定所述层。
