Compositions to deposit an active substance on a target surface (i.e. skin, hair). The active substance remains on the surface after the product is rinsed off the surface. The preferred deposition is from compositions-containing an anionic or nonionic active in the co-presence of an anionic surfactant. The compositions contain carrier particles having a zwittetionic or cationic surface and a plurality of outwardly protruding filaments containing charged organocarbyl groups. The active substance is contained within the carrier particles.
