  • Patent number: 9820932
    Abstract: The present invention relates to cosmetics comprising a hydroxyl compound obtained by the reaction of a di- or higher-valent alcohol with a monovalent carboxylic acid and dimer acid, characterized in that the hydroxyl compound is obtained by reacting diglycerin with isostearic acid, and then reacting the obtained ester compound with dimer acid, wherein a molar ratio among diglycerin, isostearic acid and dimer acid is in the range of 1.0:1.4 to 1.6:0.5 to 0.8. The present invention provides cosmetics comprising the hydroxyl compounds having a high hydroxyl value.
    Type: Grant

  • Patent number: 7824663
    Abstract: The present invention provides a lip gloss composition having appropriate adhesion, spreadability, durability, practical properties such as gloss on the applied surface, storage stability, and safety to skin. A lip gloss composition, comprising (A) 20 to 60 parts by mass of polyglyceryl-2 dimer dilinoleate isostearate and/or hydrogenated polyisobutene; (B) 0.5 to 1.0 part by mass of a polamide resin with an amide terminal group and/or a polyamide resin with an ester terminal group; (C) 1.75 to 7.0 parts by mass of a dextrin ester of an aliphatic: (D) 20 to 55 parts by mass of at least one hydroxy compound selected from the group consisting of diisostearyl malate, polyglyceryl-2 diisostearate polyglyceryl-2 triisostearate, dipentaerythrityl diisostearate and dipentaerylthrityl trisostearate; and (E) 15 to 40 parts by mass of a liquid oil having a viscosity of 5 to 400 mPa·s at 25 degrees C., wherein a total amount of (A) to (E) is 100 parts by mass and the ratio by mass (C)/(B) is 3.5 to 7.0.
