The present invention relates to an anti-aging composition for external use on skin, and more particularly, to an anti-aging composition for external use on skin comprising at least one of catechins and flavonols as an active ingredient to inhibit decomposition and promote generation or protection at the dermis-epidermis junction.

Composition of skin external application for anti-aging

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.

Disclosed herein are cationic polymer nanocapsules encapsulating an oil-soluble active ingredient, and a cosmetic composition containing the same. The cationic polymer nanocapsules have a molecular weight of 5,000-100,000, a surface potential of 5-100 mV and a particle size of 50-500 nm. Also, disclosed is a cosmetic composition containing said cationic polymer nanocapsules.

Cationic polymer nanoparticles encapsulating an active ingredients, and the cosmetic composition containing the same

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-&#x3b1;), 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.

Composition for skin external application containing gallocatechin gallate for moisturizing effect on the skin

Disclosed is a pentaerythritol derivative represented by the following Formula 1, which improves moisture retaining ability of the stratum corneum when applied to the skin, and shows especially high moisturizing ability even in dry conditions. wherein R is independently saturated or unsaturated C6-C18 alkyl group; m and n are the same or different integers of which m is 0 to 10 and n is 1 to 10.

Pentaerythritol derivatives

The present invention relates to a cosmetic composition containing hydrolysates of icariin, and more particularly, a cosmetic composition containing hydrolysates of icariin including icaritin, icariside I and icariside II. The hydrolysates of icariin is prepared by a method comprising the steps of: (a) obtaining an extract from a plant containing icariin using water or an organic solvent; and (b) hydrolyzing the plant extract with an acid, a base, an enzyme or a microorganism producing the enzyme. The cosmetic composition according to the present invention is employed for anti-oxidant, anti-aging, whitening or anti-wrinkling effects.

Cosmetic composition containing hydrolysates of icariin

Disclosed herein is a skin external composition for alleviating dry skin symptoms, which contains an extract ofMiq. as a main component and further contains an extract ofWolf, as well as the use thereof for skin-moisturizing cosmetics. The composition contains, as active ingredients, theMiq. extract and theWolf extract, which are prepared by extracting each ofMiq. andWolf using water, ethanol, methanol, hexane, ethyl acetate or butanol.

Disclosed is a combination for skin external use, which contains as an active ingredient an herbal extract complex consisting of Chinese herbal extracts of Granate bark, seed of-andvar.. More particularly, disclosed is a composition for skin external use containing an herbal extract complex, which is prepared by mixing the Chinese herbs with each other at an optimal ratio to prepare an herbal mixture and extracting the herbal mixture to prepare an herbal extract complex, and thus shows the effects of promoting the differentiation of skin keratinocytes, restoring impaired skin barrier function and increasing skin moisturization compared to extracts obtained by extracting each of the herbs alone.

Composition for skin external application containing complex of herbal extracts

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.

Sesamol derivatives or their salts, the process for preparing the same, and the skin external composition containing the same

The present invention relates to a method for stabilizing enzyme and water- and oil-soluble active components using polyol/polymer microcapsules, and to a cosmetic composition containing the enzyme and the microcapsules. More particularly, the present invention relates to polyol/polymer microcapsules which effectively stabilize the enzyme and active components, which are unstable in the formulations, through increasing the solubility thereof in hydrophobic polymer by using polyol, and to a method for preparing the polyol/polymer microcapsules.

Method for stabilizing active components using polyol/polymer microcapsule, and cosmetic composition containing the microcapsule

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.

Thermotropic liquid crystal polymer microcapsules, a method for preparing the same, and cosmetic compositions containing the same

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.

Hydroxy pyranone derivative and preparation method thereof

There are provided amphiphilic biodegradable block copolymers comprising polyethylenimine (PEI) as a hydrophilic block and aliphatic polyesters as a hydrophobic block, which can form various size of polymer aggregates and have very low critical micelle concentration, approximately 10 g/l in comparison with low-molecular-weight micelle, and self-assembled polymer aggregates formed from the block copolymers in aqueous milieu, which can be applied to solubilization of insoluble drug and a delivery system of proteins, genes or drugs.
