摘要：
The present invention relates to a core shell microcapsule wherein the liquid core of the microcapsule comprises solvent and climbazole 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) into an aqueous phase containing, or having been added, a second water-soluble component of a shell-forming polymerization system； (d) forming the microcapsules by reacting the first and second components of the polymerization system to encapsulate the dissolved climbazole 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 climbazole and solvent wherein climbazole is dissolved in the solvent in a weight ratio of at most 8: 1, preferably at most 5: 1 solvent.a presente invenção se refere a uma microcápsula de invólucro do núcleo em que o núcleo líquido da microcápsula compreende o solvente e climbazol dissolvidos no solvente em uma proporção em peso de, no máximo, 8:1, de preferência, no máximo, 5:1, solvente:climbazol. a presente invenção também se refere a um processo para a fabricação da microcápsula de invólucro do núcleo que compreende as etapas de: (a) dissolver o climbazol em solvente para a formação de uma fase oleosa； (b) misturar a fase oleosa com um primeiro componente solúvel em óleo de um sistema de polimerização formador de invólucro； (c) dispersar a mistura da etapa (b) em uma fase aquosa que contém, ou foi adicionado, um segundo componente hidrossolúvel de um sist
