摘要:
The present invention relates to a composition for external skin application having a skin-moisturizing effect, which comprises gallocatechin gallate as an active ingredient. More particularly, the composition for external skin application comprises gallocatechin gallate as an active ingredient to activate peroxisome proliferator activated receptor isoform alpha (PPAR-α), to stimulate expression of filaggrin and involucrin that are skin-moisturizing factors, and thus to provide excellent anti-drying and skin-moisturizing effects. More particularly, the composition for external skin application may further comprise theobromine and quercetin in addition to gallocatechin gallate to maximize such effects.

The present invention provides hydroxy pyranone derivatives and a method for preparing the hydroxy pyranone derivatives. The hydroxy pyranone derivatives of the present invention are significantly effective in promoting the biosynthesis of collagen and in inhibiting the activity of collagenase, i.e. an enzyme for decomposing collagen, to have anti-wrinkle efficacy, and can be incorporated into medicines or external applications for lessening skin-wrinkles.

The present invention relates to a sesamol derivative or its salt, and a skin external composition containing the same. More particularly, the invention relates to a sesamol derivative or its salt, which consists of sesamol and 3-aminopropane phosphoric acid, linked with each other by a phosphoric acid diester bond, and can be degraded into sesamol and 3-aminopropane phosphoric acid by enzymes present on the skin so as to simultaneously show the physiological activities of sesamol and 3-aminopropane phosphoric acid, as well as a preparation method thereof and a skin external composition containing the same.
摘要:
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.
摘要:
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.
摘要:
Disclosed are an extractor having a “pottery with dark brown glaze” called “Onggi” in Korean, and a method of extracting using the same. The extractor includes a body, a body cover, a heating part, a pottery and a gas valve. The pottery is located within the body. The extractor extracts by injecting nitrogen gas, etc. into the body through a gas valve, thereby rendering the inside of the body to be high pressure state during extraction. Thus, the inside of the body is maintained under high pressure during extraction. Accordingly, an extract is located only within the pottery, and thus changes that can be caused while an extract contacts with the body can be prevented.
