  • Anhydrous, hydrophilic absorbent wound dressing
    Publication number: 20040142020
    Abstract: An anhydrous, hydrophilic wound dressing containing a superabsorbent polymer. Its anhydrous nature allows it, when applied to a wound site, to absorb wound fluid.
    Type: Application

  • Elegant hydrogenated castor oil ointments
    Patent number: 6479060
    Abstract: A topical ointment pharmaceutical composition that uses a lipophilic base, a pharmaceutical active and, dispersed in the base, from about 1% to about 50% by weight of the total composition of hydrogenated non-melted castor oil in powder form. The result of using hydrogenated non-melted castor oil in powder form is a surprising pharmaceutical elegance perceived to be smoother in texture and more spreadable than an ointment made by melting the hydrogenated castor oil.

  • Methods for preparing gelatin capsules containing fragrances
    Patent number: 6099858
    Abstract: Methods for preparing soft gelatin capsules containing fragrances are disclosed. The desired fragrance is dissolved in a solvent system comprising a volatile solvent, a non-volatile cosolvent, or a combination of a volatile solvent and a non-volatile cosolvent or cosolvents. The resulting mixture is then encapsulated between gelatin ribbions prepared with an odor-free gelatin plasticized with a partially dehydrated, hydrogenated glucose syrup.
