  • Triterpenic acid derivative and preparation for external application for skin comprising the same
    Patent number: 7718635
    Abstract: In a triterpenic acid having hydroxyl groups, at least one of the hydroxyl groups is phosphorylated to produce a phosphorylated triterpenic acid and/or a salt thereof, thereby improving the solubility of the triterpenic acid in a preparation for external application for the skin and allowing the physiological activity of the triterpenic acid to be exerted satisfactorily. The phosphorylated triterpenic acid is preferably, for example, ursolic acid phosphate and/or a salt thereof. The preparation for external application for the skin is preferably a cosmetic, particularly preferably a quasi-drug.
    Type: Grant
    Filed: April 13, 2006
    Date of Patent: May 18, 2010
    Assignee: Pola Chemical Industries Inc.
    Inventors: Michio Ochiai, Kenichi Goto, Yoshihiro Tokudome, Shigenari Hirokawa

  • Polyglycerol compounds and cosmetic products containing the same
    Patent number: 4636525
    Abstract: A hydrophilic cosmetic product contains a novel randomly polymerized polyglycerol, polytrimethylene- or -tetramethylene-oxide condensate of an 8-36 carbon aliphatic alcohol or fatty acid useful as a non-ionic surface active agent.
    Type: Grant
    Filed: March 12, 1986

  • Cosmetics
    Patent number: 4250193
    Abstract: Disclosed are cosmetics containing an oily bisdiglyceryl ether compound. This novel compound can be prepared by adding an alkylene glycol, dialkylene glycol, trialkylene glycol or tetraalkylene glycol dropwise to an alkylglycidyl ether using as a catalyst a boron trifluoride ether complex, other Lewis acid, sodium hydroxide or potassium hydroxide and removing the catalyst with the use of sodium carbonate, calcium carbonate, potassium carbonate, these aqueous solutions or water upon heating, followed by rectification of the resultant oily liquid under reduced pressures. The cosmetics of this type do not cause any dermatitis or skin disease due to the absence of surface active agents.
