The present invention relates to core-shell capsules prepared with linear and/or branched and cyclic aliphatic polyisocyanates. In particular, the present invention discloses a core-shell capsule, wherein the shell comprises or consists of a polymeric material which is produced or producible by reacting two components, the first component comprising or consisting of at least one linear aliphatic polyisocyanate and/or at least one branched aliphatic polyisocyanate having more than one isocyanate group, respectively, and at least one cyclic aliphatic polyisocyanate having more than one isocyanate group, the second component comprising or consisting of one or more crosslinking agent(s). Furthermore, a product comprising the present core-shell capsule, a process for producing the present core-shell capsules and the use of the present core-shell capsules is provided.

Core-shell capsules prepared with linear and cyclic aliphatic polyisocyanates

The present invention primarily relates to a method for producing a powder containing a plurality of capsules incorporated into crystals, wherein these capsules contain one or more ingredients. Further, the present invention relates to the respective powder, as well as product containing this powder, the use of the powder as well as methods for producing respective products and methods for perfuming substrates.

Powder containing crystals comprising ingredients enclosed therein

The invention relates to the field of capsules having a high load of active ingredients or substances, to the use thereof in cosmetic preparations, pharmaceuticals, household products, cleaning agents and technical compositions, e.g. adhesive and coating compositions, and to the manufacturing of the capsules.

Microcapsules

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.

Method for the production of scent capsules with improved surfactant stability

The invention relates to microcapsules having a particle size distribution that has at least two maxima, wherein the main maximum of the particle size lies in the range of 5 to 100 &#x3bc;m and wherein the volume assumed by the microcapsules that have a particle size less than &#xbc; of the particle size of the main maximum is greater than approximately 20% of the total volume of the microcapsules.
