Microcapsules, useful in care or make-up composition for keratinous matters, comprise a polymer envelope and/or wax encapsulating an aqueous medium containing an acrylic polymer with phosphorylcholine group

摘要

Microcapsules comprise a polymer envelope and/or wax encapsulating an aqueous medium containing an acrylic polymer with phosphorylcholine group. Independent claims are included for: (1) the preparation of the microcapsules comprising solubilization of an acrylic polymer having phosphorylcholine group in an aqueous medium, emulsification of the aqueous solution in a solution containing at least a polymer insoluble in water and/or a wax insoluble in an organic solvent with water, emulsification of the obtained water-in-oil emulsion in an aqueous solution containing a stabilizing agent of the emulsion and elimination of the organic solvent by evaporation to give the microcapsules in an aqueous suspension form; and (2) a composition comprising the microcapsules in a medium.
