    • Fabric softening compositions, preferably in liquid form, for use in the rise 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.
    • 织物软化组合物,优选为液体形式,用于家庭洗衣操作的上升循环,通过:(a)使用某些受保护的水敏感材料,特别是环糊精和香料的颗粒复合物,其在织物软化组合物和/ 或洗涤剂组合物,例如,将所述颗粒状复合物嵌入基本上不溶于水的较高熔点的保护材料中,优选非水溶胀性和在正常储存条件下为固体,但是在自动织物中遇到的温度下熔化 干衣机(洗衣机); (b)使用去污聚合物帮助将水不溶性颗粒悬浮在水性织物软化组合物中;和/或(c)通过熔化所述高熔点材料来制备所述受保护的颗粒状水敏感材料(复合物),将所述颗粒状复合物 或其它水敏材料,并将所得熔融混合物分散在水性介质,特别是表面活性剂溶液或水性织物柔软剂组合物中,并冷却以形成颗粒状复合物的小而平滑的球形颗粒,或其它 水敏感材料,基本上被高熔点材料保护。
