Abstract
Abstract Perfume particles are disclosed comprising perfume dispersed within certain water-insoluble polymeric carrier materials. Cleaning and conditioning compositions comprising these perfume particles are also disclosed. The perfume particles allow for preservation and protection of perfumes which are susceptible to degradation or loss in storage and in harsh cleaning conditions. The particles further allow for efficient delivery of a large variety of perfume types to fabrics or other surfaces.
