  • N-aralkylcarbonyldiamine compounds and personal care compositions comprising the same
    Patent number: 10307355
    Abstract: The present invention provides novel N-aralkylcarbonyldiamine compounds having a structure as set forth in Structure I. The structures are not quaternized. When these novel unquaternized compounds are used in personal care compositions, particularly personal care skin compositions, they are more stable and provide unexpected cosmetic advantages (e.g., against wrinkles, aging skin, etc.) when delivered from the personal care skin compositions.
