A vesicle-containing composition comprising; (A) a perfume, (B) a silicone oil, (C) a silicone surfactant, (D) one or more selected from the group consisting of ethanol, propylene glycol, dipropylene glycol, and 1,3-butylene glycol, and (E) water; wherein the (C) silicone surfactant forms vesicles, and the (A) perfume and the (B) silicone oil are present in the vesicle bilayer membrane.
Abstract:
A method of preventing darkening of the skin or inhibiting melanization caused by the irradiation of the melanin monomers with long wavelength ultraviolet rays having a wavelength of 320-400 nm as well as a polymerization inhibitor of a biological dihydroxyindole compound comprising 3-O-ethyl ascorbic acid and an external skin treatment composition containing the same.
Abstract:
An objective of the invention is to provide an oil-in-water emulsion cosmetic with a transparent to translucent appearance, that can stably and finely emulsify even a relatively large amount of a polar oil with a small amount of a surfactant. The oil-in-water emulsion cosmetic according to the present invention is characterized by containing (A) a non-ionic surfactant that has an HLB of 8 to 12; (B) a polar oil that is liquid at 25° C. and that has an IOB of 0.1 or higher; and (C) a water-soluble solvent; wherein the (A)/(B) ratio is 0.4 to 3.

[Solution] An external-use skin preparation composition comprising (A) a cyclic carboxamide derivative having a specific structure or a salt thereof, and (B) Vitamin B6.
Abstract:
[Object] Provided is an external-use skin preparation composition that effectively inhibits elastase activity. [Solution] An external-use skin preparation composition comprising (A) a cyclic carboxamide derivative having a specific structure or a salt thereof, and (B) adenosine, an adenosine derivative or a salt thereof.
Abstract:
[Problem] To provide an oil-in-water emulsion cosmetic having an excellent feel in use. [Solution] An oil-in-water emulsion cosmetic comprising (A) a cyclic carboxamide derivative having a specific structure or its salt, (B) a straight-chain higher fatty acid having 16 or more carbon atoms, (C) a higher alcohol, (D) a nonionic surfactant, (E) an oil, and (F) water.
Abstract:
The present disclosure relates to providing a substance and a composition that promote the proliferation of epidermal stem cells and are effective in improving wrinkles and barrier function from the viewpoint of maintaining or improving quality of life (QOL) in terms of both health and beauty. More specifically, a composition including 1-(2-hydroxyethyl)-2-imidazolidinone (HEI) or a derivative thereof and a seaweed extract such as Marinwort IPC-12 AGS can be used to promote the proliferation of epidermal stem cells and obtain a beneficial effect on wrinkles and barrier function.
Abstract:
A polymer compound in which coumarin or a derivative thereof is bonded to at least one terminal of a skeletal polymer. A flow property of the polymer compound is reversibly changeable from a first state to a second state by irradiation with light at a first wavelength and from the second state to the first state by irradiation with light at a second wavelength different from the first wavelength.
