Abstract: Washing and cleaning agents may include microcapsules comprising a core material where the core material may include at least one fragrance and a shell. The shell may consist of at least one first layer and one second layer with different chemical compositions. The shell may have a biodegradability, measured in accordance with OECD 301 F, of at least 40%. Such agents may be used for conditioning textiles or for cleaning textiles and/or hard surfaces.

Abstract: In accordance with a first aspect, the invention relates to microcapsules for use in a high demand area selected from detergents and cleaners, cosmetic products, adhesive systems, paints and dispersions, coating materials comprising a core material and a shell, wherein the shell consists of at least a first and a second layer whose chemical compositions differ, and wherein the shell has a biodegradability measured according to OECD 301 F of at least 40%. The invention further relates to a product comprising microcapsules, wherein the product is selected from the group consisting of an adhesive system; a cosmetic product; a pharmaceutical product; a coating material, in particular a coated paper; a heat storage coating, a self-healing coating or a corrosion coating; and a coating of functional packaging materials.
