  • Patent number: 11166887
    Abstract: A water-in-oil emulsified cosmetic preparation that, even without substantially comprising a UV scattering agent: exhibits a higher UV protection effect than immediately after application, as a result of coming in contact with moisture, has excellent appearance, usability, and washability. The water-in-oil emulsified cosmetic preparation includes 6%-40% by mass of a UV absorber (A), an oil phase thickener (B), and at least one hydrophobic powder (C) selected from (i)-(iii), namely (i) hydrophobized talc, (ii) silicone powder having an average particle diameter of at least 30 ?m, and (iii) crosslinked polymethyl methacrylate powder having a crosslinking density of at least 40%; and not including a UV scattering agent or containing no more than 6% by mass of same.

  • Publication number: 20210106507
    Abstract: The problem to be solved by the present invention is to increase durability and suppress irregularities an oil-in-water type emulsion containing an agar microgel. A method for accomplishing this goal comprises dispersing in the makeup 0.5 to 10% by mass of a core-corona microgel. The resulting compositions are highly durable and excellent in feeling in use, and particularly excellent in freshness.

  • Publication number: 20210077365
    Abstract: A water-in-oil emulsified cosmetic preparation that, even without substantially comprising a UV scattering agent, exhibits a high UV protection effect. This water-in-oil emulsified cosmetic preparation includes: 6%-40% by mass of a UV absorber (A); at least 15% by mass of a non-volatile polar oil component (B) containing an ester bond (and not including the UV absorber (A)); and 0.5%-15% by mass of an oil phase thickener (C). It is particularly preferable that the present invention also includes a powder (D) having an average particle diameter of no more than 15 ?m.

  • Publication number: 20200289400
    Abstract: An oil-in-water-type emulsion cosmetic contains an ultraviolet ray scattering agent and which has preparation stability in a system where a water-soluble alkyl-substituted polysaccharide derivative and another emulsifying agent coexist is further improved. The oil-in-water-type emulsion cosmetic containing (A) a water-soluble alkyl-substituted polysaccharide derivative, (B) a nonionic surfactant and (C) an ultraviolet ray scattering agent, wherein the blend ratio [(A)/(B)] of the water-soluble alkyl-substituted polysaccharide derivative (A) to the nonionic surfactant (B) is 1.54 or less, and the blend ratio [(A)/(C)] of the water-soluble alkyl-substituted polysaccharide derivative (A) to the ultraviolet ray scattering agent (C) is 0.02 or less.

  • Publication number: 20170333301
    Abstract: The object is providing a water-in-oil emulsion sunscreen cosmetic having a property not present in the prior art, in which UV protection ability improve upon contact with water, sweat and the like in comparison with that directly after application, and also having pleasant texture and easy to wash off. The present invention provides a water-in-oil emulsion sunscreen cosmetic comprising (A) 6 to 40 mass % of a UV protective agent; (B) an organic-modified clay mineral; (C) an oil-phase-thickening agent, other than (B) and (D) a silicone-based surfactant having an HLB of less than 8, wherein the ratio, [total quantity of component (B) and component (C)]/[total quantity of (E) non-volatile liquid oils except silicone oils], is 0.04 or more and less than 0.68.
