Compositions for providing controlled-release of an active material comprise a dispersant and microcapsules containing the active material and a stabilizer. 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. The stabilizer improves the stability of the microcapsule. 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 and a stabilizer.
控制释放活性物质的组合物包括分散剂和含有活性物质及稳定剂的微胶囊。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,组合物可以提供可控释放的香味,同时控制恶臭。稳定剂可提高微胶囊的稳定性。在表面上控制释放活性物质的方法包括以下步骤:将表面与包含分散剂和含有活性物质及稳定剂的微胶囊的组合物接触。
