Compositions for providing controlled-release of an active material comprise a dispersant and microcapsules containing the active material. The compositions contain the dispersant and/or microcapsules at relatively low levels to avoid negatively impacting the surfaces treated with the compositions. The active material is preferably a perfume and the composition provides a controlled-release scent, along with controlling malodor when the compositions further comprise optional odor control agent. Methods of providing a controlled-release of an active material on a surface comprise the step of contacting the surface with a composition comprising a dispersant and microcapsules containing an active material.
                            控制释放活性物质的组合物包括分散剂和含有活性物质的微胶囊。组合物中分散剂和/或微胶囊的含量相对较低,以避免对用组合物处理过的表面产生负面影响。活性材料最好是香
水,当组合物进一步包含可选的气味控制剂时,组合物可提供可控释放的香味,同时控制恶臭。在表面上控制释放活性物质的方法包括以下步骤:用包含分散剂和含有活性物质的微胶囊的组合物接触表面。
