Abstract (en)
[origin: EP2689836A1] A process for the preparation of a microcapsule composition, wherein the shell of the microcapsules is essentially made of silica and the core comprises at least one lipophilic component, comprising the steps of: a) providing an aqueous dispersion comprising at least one lipophilic component (A) and b1) adding to the aqueous dispersion provided in step a) a water glass solution and an acid, or b2) adding to the aqueous dispersion provided in step a) a silicic acid solution and a base, wherein the addition is effected such that the pH of the mixture resulting during the addition of the water glass solution in step b1) or during the addition of silicic acid solution in step b2) is kept in a range of 6 to 9.
