  • Retinoic acid-containing compositions
    Patent number: 5700483
    Abstract: Novel retinoic acid-containing topical compositions in the form of creams, lotions, gels, and the like, are disclosed. These compositions contain a urethane compound having a molecular weight of up to about 200,000, prepared by reacting approximately two moles of a hydroxy-terminated linear alkylene or polyalkylene glycol with approximately one mole of a monomeric organic diisocyanate. The presence of the urethane compound leads to decreased percutaneous transmission of the retinoic acid, resulting in reduced skin irritation but undiminished therapeutic effectiveness of the retinoic acid when compared to retinoic acid-containing topical formulations otherwise identical except for the absence of a urethane compound.
    Type: Grant
    Filed: September 6, 1996
    Date of Patent: December 23, 1997
    Assignee: Penederm, Inc.
    Inventors: John W. Quigley, Jr., Harris Goodman
  • Retinoic acid-containing polyether-polyurethane compositions
    Patent number: 5650171
    Abstract: Novel retinoic acid-containing topical compositions in the form of creams, lotions, gels, and the like, are disclosed. These compositions contain a urethane compound having a molecular weight of up to about 60,000, prepared by reacting approximately two moles of a hydroxy-terminated linear alkylene or polyalkylene glycol with approximately one mole of a monomeric organic diisocyanate. The presence of the urethane compound leads to decreased percutaneous transmission of the retinoic acid, resulting in reduced skin irritation but undiminished therapeutic effectiveness of the retinoic acid when compared to retinoic acid-containing topical formulations otherwise identical except for the absence of a urethane compound.
