The present invention relates to a process for preparing biodegradable polyurea/polyurethane microcapsules, preferably perfume-containing polyurea/polyurethane microcapsules, which have improved biodegradability 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 according to 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 lotions or scent enhancers, cosmetics, personal care products, agricultural products, pharmaceutical products or printing coatings for paper. Ultimately, the present invention relates to consumer products comprising such microcapsules or microcapsule dispersions.

A method for manufacturing microcapsules containing an active substance, the method including: providing an aqueous solution of a surfactant, an oily phase comprising the active substance and a first monomer, and a polar phase comprising a second monomer; preparing an oil-in-water emulsion by adding the oily phase to the aqueous solution of the surfactant; adding the polar phase to the oil-in-water emulsion, in order to obtain a polymer in a reaction mixture, by polymerization of the first monomer and the second monomer; isolating the microcapsules, including a wall formed by the polymer and containing the active substance, from the reaction mixture; wherein the polymer is a poly(beta-amino ester). Microcapsules obtained by the method.

Method for manufacturing microcapsules enclosing a substance referred to as the active substance, in which method: there are provided an aqueous solution of a surfactant, an oily phase comprising the active substance and at least a first monomer X, and a polar phase having at least a second monomer Y; an O/W emulsion is prepared by adding the oily phase to the aqueous solution of the surfactant; the polar phase is added to the O/W emulsion in order to obtain a polymer by polymerisation of the X and Y monomers; starting from this reaction mixture, the microcapsules are isolated and comprise a wall which is formed by the polymer and which encloses the active substance; the polymer is a poly(beta-amino ester).

The invention relates to an easy and mild method of encapsulating lipophilic compounds. To induce coacervation, no acid needs to be added. Therefore, the coacervate capsules of the invention may encapsulate lipophilic actives which are sensitive to acid degradation. In a preferred embodiment of the invention, a vegetarian rapeseed protein isolate is used to encapsulate vegetarian algae oil. The thus obtained product is a vegetarian or even vegan source of polyunsaturated fatty acids.
