Abstract:
PURPOSE: A method and composition for promoting skin regeneration using icariside II is provided to promote proliferation of transient amplifying cells of epidermis base and promote skin regeneration. CONSTITUTION: An icariside II of chemical formula 1 promotes proliferation of skin cells in skin cells. The skin cell is transient amplifying cells(TA cells). A composition for promoting skin regeneration contains the icariside II as an active ingredient. The content of the active ingredient is 0.001-10 weight% based on total weight. The composition regenerates epidermis by promoting proliferation of the TA cells. The composition increases the number of TA cells which express CD71 protein (Cluster of Differentiation 71 Protein) and α6 integrin. The composition increases the expression of CD200(Cluster of Differentiation 200).
Abstract:
PURPOSE: A skin external composition containing ginseng seed oil or ginseng seed skin extract is provided to ensure skin improvement effect without side effects. CONSTITUTION: A skin external composition contains ginseng seed extract as an active ingredient. The ginseng seed extract is 0.001-100 weight% of ginseng seed oil or 0.001-10 weight% of ginseng seed skin extract. A method for extracting ginseng seed skin comprises: a step of pulverizing dried ginseng seed and placing the ginseng seed at room temperature in hexane organic solvent to remove oil from the ginseng seed; a step of placing the remaining ginseng seed skin in organic solvent containing water or organic solvent at room temperature; and a step of filtering extract and concentrating.
Abstract:
Disclosed herein is a method for preparing a powder having a surface modified with a water-repellent ultra-thin layer. The disclosed preparation method comprises modifying the powder with the water-repellent ultra-thin layer by a vapor phase reaction using a high-boiling-point acryl silicone OEt-based compound and branched alkyl-silicone OEt-based compound and an alkylsilane having relatively low boiling point. When the powder is used in cosmetics, it shows excellent usability due to improved water repellency.
