The present invention relates to a personal care composition at least comprising a biosurfactant and a hydrophilic cationic or pseudo-cationic active compound. The present invention also relates to a method of enhancing or facilitating a deposition of hydrophilic cationic or pseudo-cationic active compound onto keratinous materials, such as hair or skin.

The present invention relates to a composition comprising (a) at least one biosurfactant; and (b) at least one carboxybetaine polymer. The composition according to the present invention can provide a stable deposition of the composition on keratinous substances, such as skin, scalp, and hair.

An aqueous cosmetic includes water, a polyhydric alcohol and carminic acid. A content of the carminic acid is greater than or equal to 0.2 mass % and less than 2 mass % based on a total amount of the aqueous cosmetic.

The present invention relates to a method for preparation of soybean leaves having a high content of an isoflavone derivative in a dark condition and soybean leaves having a high content of an isoflavone derivative prepared thereby. Specifically, treatment of a soybean plant 20 days to 60 days after seeding with a predetermined concentration of ethylene in a dark condition was found to accumulate higher concentrations of isoflavone derivatives in soybean leaves than treatment with ethephon in a light condition, which requires a high level of energy. Therefore, when used, the method of the present invention can economically and quickly prepare soybean leaves having a very high content of isoflavones, and the soybean leaves having a high content of isoflavone derivatives, an extract of the soybean leaves, and a fraction of the extract can be advantageously used as a food and medicine material against diseases caused by estrogen unbalance and deficient antioxidant activity.

The present invention provides a novel glycerol glucoside-based compound having excellent ultraviolet light shielding performance and anti-inflammatory effect, and a composition including the compound for ultraviolet light shielding or anti-inflammation.

The invention relates to O-quinone compounds of general formula (I) as agents neutralising nitric oxide, and to the therapeutic or cosmetic use thereof.

Provided is a composition for inhibiting hair graying, having an excellent effect of preventing the occurrence of gray hair, and a use thereof. A composition for inhibiting hair graying, of the presently claimed subject matter, activates the Wnt and β-catenin signaling pathway to promote melanin synthesis in hair, thereby having remarkably excellent hair graying (canities) inhibition, prevention, improvement, alleviation, delaying, or treatment effects.

A composition contains 2 to 6 parts by weight of at least one rhamnolipid, 1 to 4 parts by weight of at least one alkyl polyglycoside, and 1 to 3 parts by weight of at least one acyl lactylate.

The invention relates to a cosmetic nail care composition in the form of a varnish, which is to be applied to the surface of the nail, characterized in that it contains an aqueous chestnut extract Castanea sativa. The invention also relates to the use of said cosmetic composition for improving the surface condition of the nail, in particular for nourishing and hydrating the nail.

An aerosol composition including an aerosol stock solution containing a cationic surfactant (A) and a linear saturated higher alcohol (B), and a propellant (C) containing carbon dioxide. The component (A) containing a mono-long-chain-alkyl cationic surfactant (A1). A content of the component (A) being 0.9% by mass or more and less than 6.0% by mass in the aerosol stock solution. A molar ratio [(B)/(A1)] of the component (B) with respect to the component (A1) being 3.0 or more and 7.0 or less in the aerosol stock solution. A content of the component (A1) in the component (A) being 90% by mass or more and 100% by mass or less, and a difference between a number of carbon atoms of the long-chain alkyl in the component (A1) and the number of carbon atoms of the component (B) being 0.
