Abstract
An effective amount of perfume/cyclodextrin complex is applied to fabric that is preferably at least partially wetted. A preferred method applies said complex to said fabric in an automatic laundry dryer. The perfume/cyclodextrin complexes are preferably incorporated into solid, dryer-activated, fabric treatment (conditioning) composition, preferably containing fabric softeners, more preferably cationic and/or nonionic fabric softeners. The complexes provide fabrics with perfume benefits when they are rewetted after drying. Volatile perfume materials, including those materials that are commonly associated with 'freshness' can be applied to the fabrics in an effective way. Clay provides protection for said perfume/cyclodextrin complexes, especially when certain materials like some nonionic fabric softeners and/or fatty acids are present and in contact with said perfrum/cyclodextrin complexes.
