Abstract: The present invention relates to a process for the preparation of biodegradable polyurea/polyurethane microcapsules, preferably perfume-containing polyurea/polyurethane microcapsules, which have a balance of biodegradability, stability and performance compared to prior art microcapsules. In addition, the present invention relates to biodegradable polyurea/polyurethane microcapsules comprising at least one lipophilic active ingredient obtainable by the process of the invention. In another aspect, the invention described herein relates to the use of such microcapsules or microcapsule dispersions comprising the microcapsules according to the invention for the manufacture of household products, textile care products, detergents, fabric softeners, cleaning agents, scent boosters, scent lotion or scent enhancers, cosmetics, personal care products, agricultural products or pharmaceutical products. Ultimately, the present invention relates to consumer products comprising such microcapsules or microcapsule dispersions.
