Abstract: The invention provides a health food which is protected from degradation caused by oxidation over a long period of time, even though the food contains no antioxidant. According to the invention, a health food active ingredient is clathrated by a cyclic oligosaccharide. The resultant health food can be protected from oxidation and degradation over a long period of time without use of an antioxidant. The cyclic oligosaccharide is preferably ?-cyclodextrin or ?-cyclodextrin.

Abstract: The invention provides a skin-revitalizing cosmetic composition for alleviating or eliminating skin problems such as dry skin, wrinkles, and age spots, the composition containing a skin-revitalizing agent at high concentration. The skin-revitalizing cosmetic composition contains a skin-revitalizing agent selected from the group consisting of aloe extract, placenta extract, hydrolyzed elastin, hydrolyzed collagen, and sodium hyaluronate, wherein the skin-revitalizing agent is in the form of nanoparticles obtained through a nanoparticle-forming treatment.

Abstract: The invention provides a facial cleansing powder composition exhibiting good latherability even when used with hard water, the composition containing, as a substitute for edetic acid, an environmentally acceptable metal-sequestering agent which is readily incorporated into facial cleansing powder. The facial cleansing powder composition contains a facial cleansing powder base, phytic acid, and starch powder, wherein the phytic acid is supported on the starch powder. The amount of phytic acid is preferably 0.01 to 2.0 wt. %. Preferably, phytic acid is supported on starch powder by mixing an aqueous phytic acid solution with starch powder and drying the mixture.

Abstract: The present invention provides a whitening cosmetic composition containing arbutin at a high concentration, whereby an improved whitening effect can be attained. In the arbutin-containing whitening cosmetic composition, arbutin is in the form of nanoparticles obtained through a nanoparticle-forming treatment of an aqueous arbutin dispersion. The composition preferably contains arbutin nanoparticles having a particle size of 10 to 150 nm in an amount of 1 to 15 wt. %.

Abstract: The invention provides a cosmetic composition which can smooth fine lines and wrinkles, impart firmness and elasticity to the facial skin, and make fine lines and wrinkles less noticeable, all within a short period of time. The cosmetic composition is in a hydrogel form and contains sodium hyaluronate, modified cornstarch, and pullulan, particularly in amounts of 0.1 to 1.0 wt. %, 0.5 to 5.0 wt. %, and 0.1 to 3.0 wt. %, respectively. The composition may further contain a dispersant.
