Abstract: An emulsion composition of the invention has macro-sized (0.01 to 5 mm) lipid capsule particles and it is for a skin cosmetic composition. An emulsion composition of the invention exhibits improved stability for its particle size by adjusting a size of the particle through a combination of liquid phase oil and integument lipid or lipoid material and encapsulating the liquid phase oil with the integument lipid. The emulsion composition of the invention has unique outward appearance and use feeling due to the macro-sized particles in it, also exhibits excellent skin safety and moisture persistence by containing no surfactant and maintains an activity of an oleophilic effective ingredient which is apt to be oxidized for a long time.

Abstract: The present invention relates to a water-in-oil-in-water multiple emulsion system and a method for preparation thereof, characterized by hydrodynamically stabilizing the multiple emulsion system by using hydrodynamic dual stabilization (HDS) technology. The HDS technology hydrophobizes water molecules in the internal aqueous phase by using a hydrogen bonding inhibitor and by improving the aggregating force between water molecules in the internal aqueous phase by using a water molecule aggregating agent.

Abstract: There are provided inorganic/polymer composite particles having good UV-scattering efficiency and improved dispersion stability in organic formulation; and a method for preparing the same, which comprises the following steps of (1) dispersing hydrophobic-treated inorganic particles in monomer and then adding initiator thereto; (2) emulsifying the inorganic dispersion of step (1) in presence of surfactant and dispersion stabilizer; and (3) suspension polymerizing the inorganic/monomer emulsion of step (2), to give inorganic/polymer composite particles.

Abstract: There are provided thermotropic liquid crystal polymer microcapsules which can show behavior of liquid crystal as it is within polymer phase due to phase separation between liquid crystal and polymer, so to be incorporated into cosmetic composition as an additive for visual effect, and in loading active ingredients within liquid crystal, can improve the stability of the active ingredients in cosmetic base; and a method for preparing the same; and cosmetic compositions containing the same.
