  • Substituted polyalkoxysiloxane compositions and methods of use
    Patent number: 8552135
    Abstract: Linear polydialkoxysiloxanes with 2-8 polymeric units have been reacted with alcohols by a transetherification reaction to provide hydrophilic and water soluble silicone products. The glycerol substituted siloxanes in particular are effective in topically treating skin lesions such as radiation burns. Compositions including the substituted polydialkoxysiloxane products inhibit biofilm formation when used as coatings on hard surfaces.
    Type: Grant

  • Hydrophilic silicones
    Patent number: 8158740
    Abstract: A process for producing a soluble silicone product is provided. The process includes the steps of chemically reacting a polydialkoxysiloxane with an aliphatic alcohol with or without a catalyst in a reaction mixture, removing produced alcohol from the mixture; recovering the water soluble portion of produced silicone product, purifying the water soluble portion; and recovering hydrophilic material in the water insoluble portion.
