microcapsule, process for manufacturing microcapsules and composition. The present invention relates to a core shell microcapsule wherein the liquid core of the microcapsule comprises the solvent and climbazol dissolved in the solvent in a weight ratio of at most 8:1, preferably at most 5:1 , solvent: climbazole. The present invention also relates to a process for manufacturing the core shell microcapsule comprising the steps of: (a) dissolving climbazole in solvent to form an oil phase; (b) mixing the oil phase with a first oil-soluble component of a shell-forming polymerization system; (c) dispersing the mixture from step (b) in an aqueous phase which contains, or has been added, a second water-soluble component of a shell-forming polymerization system; (d) form the microcapsules by reacting the first and second components of the polymerization system to encapsulate climbazol dissolved in the solvent; and (e) optionally separating the formed microcapsules from the aqueous phase. The present invention also relates to a hair care composition comprising the surfactant and at least 0.1% by weight of a core shell microcapsule comprising a polymer shell and a core comprising climbazol and solvent in which climbazol is dissolved in the solvent in a weight ratio of at most 8:1, preferably at most, 5:1 solvent. |
