Disclosed are microcapsule compositions having a microcapsule that contains a microcapsule core and a microcapsule shell encapsulating the microcapsule core. The microcapsule has a particle size of 1 micron to 100 microns in diameter. The microcapsule core contains an active material. The microcapsule shell is formed of at least three moieties, in which a first moiety is derived from a polygalactomannan, a second moiety is derived from a polyisocyanate, and a third moiety is derived from a multi-functional aldehyde or a tannic acid.

Disclosed are microcapsule compositions and their preparation methods. The microcapsule composition has a microcapsule dispersed in an aqueous phase. The microcapsule has a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material selected from the group consisting of a fragrance, cosmetic active, malodor counteractant, and combinations thereof. The microcapsule wall is formed of a polymeric network comprising of at least three moieties: (i) a first moiety derived from a chitosan, (ii) a second moiety derived from a polyisocyanate, and (iii) a third moiety derived from a polyphenol. Also disclosed are consumer products contain such a microcapsule composition.

Disclosed are microcapsules each having a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material and the microcapsule wall contains hydroxyethyl cellulose moieties. Also disclosed are preparation method and consumer products containing the microcapsules.

A polyurethane foam, polyisocyanurate foam or polyurea foam is obtainable from the reaction of a mixture comprising A) a compound reactive towards isocyanate (NCO-reactive compound); B) a blowing agent selected from the group comprising linear, branched or cyclic C1 to C6 hydrocarbons, linear,branched or cyclic C1 to C6 fluorocarbons, N.sub.2, O.sub.2, argon and/or CO.sub.2, where the blowing agent B) is present in the supercritical or near-critical state; C) a polyisocyanate; D) an amphiphilic isocyanate; and E) optionally a surfactant and F) optionally other auxiliaries and additives. The invention further relates to the production of this polyurethane foam, where the blowing agent is emulsified in the isocyanate component containing amphiphilic isocyanate.

The present invention relates to a new process for preparing polyisocyanates containing isocyanurate groups and being flocculation-stable in solvents from (cyclo)aliphatic diisocyanates.
