  • Personal care applications of emulsions containing elastomeric silanes and siloxanes with nitrogen atoms
    Patent number: 8071079
    Abstract: Oil-in-water (O/W) and water-in-oil (W/O) emulsions and microemulsions containing elastomeric silanes or siloxanes preferably having quaternary ammonium groups are generally made by reacting organic quaternary ammonium compounds having epoxide groups or halohydrin groups, with silanes or siloxanes having amino groups. The reaction is carried out in an aqueous polar phase containing a crosslinking agent and surfactant. The emulsions and microemulsions are especially useful for treating hair, skin, or the underarm.
    Type: Grant
    Filed: April 15, 2004
    Date of Patent: December 6, 2011
    Assignee: Dow Corning Corporation
    Inventors: Julie Sue DeCaire, Bethany Johnson, Michael Richard Lafore, Zuchen Lin

  • Lyotropic liquid crystals and vesicles
    Patent number: 7781556
    Abstract: Silicone based liquid crystal and vesicles are prepared by first reacting (A) an ?Si—H containing polysiloxane, (B) a mono-alkenyl polyether, in the presence of a platinum catalyst until an ?Si—H containing polysiloxane with polyether groups (C) is formed. The ?Si—H containing polysiloxane with polyether groups (C) is then reacted with (D) an unsaturated hydrocarbon such as an ?,?-dienes, and (E) water, in the presence of a platinum catalyst until the silicone based liquid crystal or vesicle is formed. The silicone based liquid crystal or vesicle can also be heated until a hard liquid crystal gel or vesicle paste are formed.
