Abstract: A method of reducing malodours in an environment, particularly an enclosed public environment subject to heavy usage and intense pedestrian traffic, comprises applying to the floor of the environment a floor treatment composition comprising a carrier and perfume-containing microcapsules, the microcapsules being rupturable to release the perfume contents. Perfume is only released when the microcapsules are ruptured by mechanical action, e.g. by being walked on, leading to release of perfume in response to use over an extended period. The length of the extended period depends on factors including the level of usage, but even in the environment of heavy usage, the extended period can be several days. Also disclosed is a floor treatment composition including an anti-static agent.
