Abstract: The present invention relates to polymer composite particles containing much organic sunscreen agents and a method of preparing the polymer composite particles, and more particularly to polymer composite particles containing much organic sunscreen agents that are spherical polymer composite particles in which solid organic Sunscreen agents are embedded between polymer matrixes by 40 to 50 wt %, include a significantly larger amount of the organic sunscreen agents than polymer composite particles of related art, have excellent light stability despite presence of a large amount of organic sunscreen agents, are superior not only in UV-A region but also UV-B region, are excellent in skin stability and feeling of use when applied to cosmetics, and can significantly improve sunscreen function, and a method of preparing the polymer composite particles.

Abstract: The present invention relates to a liquid drop releasing cosmetic material, and particularly to a cosmetic material of releasing liquid drop by rubbing, which comprises: (a) a card house structure having a space formed with a plate-shaped substance therein; and (b) liquid drop contained in the space of the card house structure. A liquid drop releasing cosmetic material according to the present invention has an excellent visual effect and feeling of use by releasing liquid drop due to rubbing during use and fundamentally solves side effect and antipathy of users due to silicone polymer because it is free from a silicone polymer, and has excellent stability in a cosmetic material of a drop releasing structure.

Abstract: The present invention relates to a hemispherical polymethylmethacrylate bead, wherein the hemispherical polymethylmethacrylate bead of the invention has high adhesive property and oil absorption when applied to cosmetics, medical supply, household items, display devices, lighting fixtures, and miscellaneous goods and especially, it enables cheerful color when applied to cosmetics in comparison with spherical polymethylmethacrylate beads.
