    • A method for preparing a lipid nano-particle containing hinokitiol is provided to obtain the lipid nano-particle which protects the hinokitiol from outside environment, shows excellent dispersing property in an aqueous phase composition and excellent physical stability not being destructed by a surfactant conventionally included in a washing agent and improves bioavailability due to good skin permeation property and persistent property after rinsing-off when applied to the washing agent. A method for preparing a lipid nano-particle containing hinokitiol comprises the steps of: (a) heating a C16-22 fatty acid or a fatty alcohol with hinokitiol to prepare a lipid molten liquid including the hinokitiol; (b) preparing a heated surfactant aqueous solution using a surfactant with an HLB(hydrophilic lipophilic balance) value of 4-15; (c) mixing the lipid molten liquid with the surfactant aqueous solution and homogenizing a mixture to prepare an oil in water(O/W) emulsion; (d) dispersing the emulsion into cooling water at a temperature of 0.5-20 deg.C to solidify lipid particles; (e) adding a difunctional agent selected from the group consisting of diamine, dialdehyde, and diisocyanate or a crosslinking agent which is a multivalent ion selected from the group consisting of Ca^2+, Al^3+, and Cr^3+ to the cooled emulsion to crosslink the lipid particles; and (f) preparing an aqueous solution or an aqueous suspension using the crosslinked lipid particles. Further, a weight of the hinokitiol is 0.1 to 50 wt.% based on 100 wt.% of lipid molten liquid.

    • A water-dispersible polymer nanocapsule is provided to stabilize a compound such as an alpha-lipoic acid perfectly, which includes both a disulfide bond and a carboxyl group and has a molecular weight of 100-1,000, thereby maintaining the initial activity thereof. And a method for preparing the same is provided to conveniently prepare the polymer nano-capsule. In the polymer nanocapsule in which a compound having both a disulfide bond and a carboxyl group and an average weight of 100-1,000 is encapsulated by a hydrophobic polymer, the hydrophobic polymer has a cationic functional group capable of absorbing the compound and a functional group capable of inducing bipole-bonding with the compound as a moiety. The compound having the molecular weight of 100-1,000 is an alpha-lipoic acid. The method for preparing the polymer nanocapsule comprises the steps of: (a) polymerizing the hydrophobic polymer; and (b) encapsulating the compound into the hydrophobic polymer. The skin external application composition comprises the polymer nanocapsule and is in the form of face lotion, lotion, massage cream, nutritive cream, pack, gel, essence, lipstick, make-up base, foundation, ointment, gel, cream, patch or spray.
