Abstract: The present invention relates to (amino)saccharide-based polyurea and/or polyurethane-based microcapsules containing at least one lipophilic active ingredient, which have a good balance of increased biodegradability, stability in product formulations, and performance compared to commercially available state-of-the-art microcapsules, which are fully synthetically based. Moreover, the present invention discloses a microcapsule slurry comprising a plurality of said core-shell microcapsules dispersed in an aqueous phase. In addition, the present invention relates to a process for the preparation of a microcapsule slurry and the biobased core-shell microcapsules contained therein as such. In a further aspect, the invention described herein relates to the use of such microcapsules or microcapsule dispersions comprising the microcapsules according to the invention for the production of various consumer products. Finally, the present invention also relates to consumer products comprising such microcapsules or microcapsule dispersions.

Abstract: The present invention relates to a process for the preparation of biodegradable microcapsules, in particular biodegradable protein- and/or polysaccharide-based microcapsules, as well as dispersions of such microcapsules (microcapsule slurry) that enclose at least one hydrophobic active ingredient. In addition, the present invention relates to biodegradable microcapsules obtainable by the process according to the invention. In another aspect, the present invention relates to the use of the microcapsules and dispersions as an ingredient in consumer products.
