Abstract: The present invention relates to a process for the preparation of polyurea/polyurethane microcapsules enclosing at least one lipophilic active ingredient, preferably perfume- or aroma-containing polyurea/polyurethane microcapsules, which can be carried out independently of pH compared to the processes for the preparation of polyurea/polyurethane microcapsules of the prior art. In addition, the present invention relates to polyurea/polyurethane microcapsules obtainable by the process of the invention. In another aspect, the invention described herein relates to the use of such microcapsules or microcapsule dispersions for the manufacture of household products, textile care products, detergents, fabric softeners, cleaning products, scent boosters, scent lotions and fragrance enhancers, cosmetics, personal care products, agricultural products, pharmaceutical products, print coatings for paper and the like.

Abstract: 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.

Abstract: What are proposed are microcapsules comprising (a) a core comprising at least one active, and (b) a capsule wall, wherein the capsule wall consists of at least three polymer layers and at least one of the polymer layers consists of a first phenolic resin, wherein the first phenolic resin comprises 3% to 50% by weight of moieties that derive from at least one aromatic polyol, and at least one further polymer layer consists of a second phenolic resin, wherein the second phenolic resin comprises 3% to 50% by weight of moieties that derive from at least one triphenol.

Abstract: The invention relates to a method for producing scent capsules with improved surfactant stability, comprising the following steps: (a) providing a scent composition containing at least one scent which has at least one functional group that can form an acid group by means of oxidation or hydrolysis, and (b) encapsulating the scent mixture, characterised in that a scent composition is used that has an acid value of no more than 5 mg KOH/g immediately before encapsulation.

Abstract: The invention relates to a method for producing microcapsules, comprising the following steps: (a) providing a first aqueous preparation containing at least one prepolymer; (b) providing a second non-aqueous preparation containing the active substance to be encapsulated; (c) mixing the aqueous and the non-aqueous phases in the presence of at least one emulsifier and/or stabilizer in order to form an emulsion; (d) polymerizing the at least one prepolymer contained in the emulsion from step (c) in order to obtain a dispersion of microcapsules that enclose the active substance; (e) hardening and cross-linking the microcapsules obtained in step (d); and optionally (f) removing the microcapsules from the dispersion and drying the microcapsules, the method being characterized in that the emulsion is formed in the presence of at least one 1,2-diol in step (c).
