Perfume particles comprise perfume dispersed within certain water-insoluble nonpolymeric carrier materials and encapsu- lated in a protective shell by coating with a friable coating material. The coated particles allow for preservation and protection of perfumes which are susceptible to degradation or loss in storage and in cleaning compositions. In use, the surface coating frac- tures and the underlying carrier/perfume particles efficiently deliver a large variety of perfume types to fabrics or other surfaces.
