The present invention relates to a method of removing malodor from fabrics; stable, aqueous odor-counteractant composition, preferably for use in the laundry; and articles comprising said composition and instructions for the method and/or benefits to be derived. The composition comprises malodor counteractants such as cyclodextrin, said cyclodextrin being protected from interaction with any other materials that might be present in said composition so as to maintain the cyclodextrin in uncomplexed form and/or, optionally, zeolites, clay, odor blockers, odor reactant such as class I and/or class II aldehydes, essential oil comprising flavanoid, metallic salt, water soluble anionic polymer, etc. to help control odor. Optionally, the composition can also contain low molecular weight polyols, chelating agents, etc. The composition is preferably essentially free of any material that would soil or stain fabric.
La présente invention concerne un procédé de désodorisation des tissus; des compositions désodorisantes aqueuses stables s'utilisant de préférence lors d'un lavage; ainsi que des articles contenant ladite composition et des instructions concernant le procédé et/ou les avantages qui en découlent. Cette composition comprend des agents désodorisants tels que la cyclodextrine, qui est protégée contre l'interaction avec toute autre substance pouvant se trouver dans la composition et ce afin de demeurer sous une forme non complexée et/ou, éventuellement, des zéolites, de l'argile, des agents anti-odeur, des produits réactifs à l'odeur tels que des aldéhydes de classe I et/ou de classe II, des huiles essentielles contenant des flavanoïdes, un sel métallique, un polymère anionique hydrosoluble etc. permettant de lutter contre les odeurs. Eventuellement, la composition de l'invention peut également contenir, entre autres, des polyols de faible poids moléculaire et des agents chélateurs. Cette composition est de préférence exempte de toute substance susceptible de salir ou de tacher les tissus.
