Fabric softening compositions, preferably in liquid form, for use in the rinse c ycle of home laundry operations are improved by: (a) using certain protected water sensitive materials, especially particulat e complexes of cyclodextrins and perfumes, which are protected in fabric softening compositions and/or detergent, compositi ons, by e.g., imbedding said particulate complex in relatively high melting protective material that is substantially water-insol uble and, preferably, non-water-swellable and is solid at normal storage conditions, but which melts at the temperatures encountered in automatic fabric dryers (laundry dryers); (b) using soil release polymers to help suspend water-insoluble particles in aqueous fabri c softening compositions; and/or (c) preparing the said protected particulate water sensitive materials (complexes) by melting the said high melting materials, dispersing the said particulate complexes, or other water sensitive material, in the molten hig h melting protective material and dispersing the resulting molten mixture in aqueous media, especially surfactant solution or aqueous fabri c softener composition, and cooling to form small, smooth, spherical particles of the particulate complexes, or other w ater sensitive material, substantially protected by the high melting material.
