Climbazole microcapsules and hair care compositions containing surfactants and crimpazole

摘要

A core-shell microcapsule, wherein the liquid core of the microcapsule contains a solvent and a Crimbazole dissolved in the solvent in a weight ratio of solvent: crimber of 8: 1 or less, preferably 5: 1 or less. Furthermore, a method for producing a core-shell type microcapsule, in which a) a step of forming an oil phase by dissolving clambazole in a solvent, and b) mixing the oil phase with an oil-soluble first component of a shell-forming polymerization system C) a step of dispersing the mixture of step b in the aqueous phase containing or added to the water-soluble second component of the shell-forming polymerization system; d) of the first and second components of the polymerization system; Forming a microcapsule by reaction and encapsulating the crimpazole dissolved in the solvent; and e) optionally separating the formed microcapsule from the aqueous phase. Furthermore, at least 0.1% by weight of core-shell microcapsules comprising a surfactant, and a polymer shell and a core comprising crimpbazole and a solvent for dissolving crimpbazole in a weight ratio of 8: 1 or less, preferably 5: 1 or less. A hair care composition comprising.
