    Abstract: PURPOSE: A nanocapsule comprising a water-dispersive anionic polymer which effectively protects an active ingredient and makes a manufacturing process of the nanocapsule easy, a method for preparing thereof and a cosmetics or a dermatological composition containing thereof are provided. CONSTITUTION: A nanocapsule comprises: (a) a lipidic core which forms or contains a lipophilic active component; and (b) a water-insoluble, continued polymer envelope, wherein the polymer envelope contains at least one synthetic water-dispersive anionic polymer which is selected from the group consisting of polyester containing a functional group of carboxylic acid and/or sulfonic acid, poly(ester amide), polyurethane and vinyl copolymer and/or a natural water-dispersive anionic polymer which is selected from the group consisting of shellac resin, sandarac gum and dammar resin. The cosmetics or dermatological composition include the nanocapsule in physiologically acceptable carrier. The nanocapsule is prepared by: (i) dissolving a lipidic phase which forms or contains the lipophilic active component and a selective coating agent in an adequate, non-toxic organic solvent having lower boiling point than water; (ii) preparing an aqueous dispersed solution of the water-dispersive anionic polymer; (iii) adding a hydrophilic surfactant to the aqueous dispersed solution of the anionic polymer; (iv) mixing the organic phase prepared from the step (i) with the aqueous phase prepared from the step (iii); and (v) preparing a condensed nanocapsule suspension by evaporating all organic phases and possible, a little aqueous phase.
