    Abstract: Fabric softening compositions, preferably in liquid form, for use in the rinse cycle of home laundry operations are improved by: (a) using certain protected water sensitive materials, especially particulate complexes of cyclodextrins and perfumes, which are protected in fabric softening compositions and/or detergent compositions, by e.g., imbedding said particulate complex in relatively high melting protective material that is substantially water-insoluble 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 fabric 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 high melting protective material and dispersing the resulting molten mixture in aqueous media, especially surfactant solution or aqueous fabric softener composition, and cooling to form small, smooth, spherical particles of the particulate complexes, or other water sensitive material, substantially protected by the high melting material.

    Abstract: Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening compositions contain (a) the reaction products of higher fatty acids with a polyamine selected from the group consisting of hydroxyalkylalkylenediamines and dialkylenetriamines and mixtures thereof, (b) cationic nitrogenous salts having only one long chain acyclic aliphatic hydrocarbon group, and optionally (c) cationic nitrogenous salts having two or more long chain acyclic aliphatic hydrocarbon groups or one said group and an arylalkyl group; these compositions provide good softening performance across major types of detergents.

    Abstract: An improved liquid material dispenser of the type which transmits fluid to be diffused from an enclosed reservoir to an exposed evaporative surface by means of a wick. A wick is provided in the form of a sheet which has a very high evaporative area compared to the volume of liquid which is retained outside the confines of the reservoir at a given time. The critical relation of evaporation area to volume of liquid outside the reservoir is such that the exposed liquid material weight per square centimeter of evaporative surface is less than 10 milligrams per square centimeter. The material to be dispensed, preferably a perfume, comprises at least 50% of materials of no more than moderate volatility as defined herein. Materials having low volatility as defined herein are minimized, and the quantity of low volatility ingredients in said liquid materials is related herein to the holding capacity of the evaporative surface of the wick. The combination of the improved dispenser and improved liquid materials to be diffused maintains the evaporating liquid material at a relatively constant composition, and the liquid material evaporates at a relatively steady rate over the life of the dispenser.
