Organic Compounds

A method of attaching hyperbranched polysaccharide into or onto microcapsule shells, said method comprising the steps of:

• dispersing droplets of a core material in a suspending medium in the presence of a shell-precursor selected from the group consisting of shell-forming monomers, pre-polymers and pre-condensates, to obtain an emulsion;
• causing said shell-forming monomers, pre-polymers or pre-condensates to react at the interface of the droplets and the suspending medium obtain a slurry of core-shell microcapsules;
• adding a hyperbranched polysaccharide;
• obtaining a composition comprising a slurry of core-shell microcapsules, wherein said hyperbranched polysaccharide is attached onto the shells of said core-shell microcapsules;
• wherein the hyperbranched polysaccharide is selected from the group consisting of amylopectins, dextrins, hyperbranched starches, glycogen and phytoglycogen and mixtures thereof;
• and wherein the addition of hyperbranched polysaccharide is effected before the shell-forming monomer, pre-polymers or pre-condensates are caused to react or during the reaction of these materials.
