  • Patent number: 8993501
    Abstract: A sprayable homogeneous and high viscosity surface cleaning gel or gel foam composition and method of cleaning is provided. The composition may include from about 70% to about 99% of a liquid carrier; from about 0.002% to about 10% of surfactant selected from the group of non-ionic, anionic, amphoteric, and zwitterionic surfactants, and mixtures thereof; from about 0.005% to about 5% of a water-soluble polymeric thickening agent; and from about 0.001 to about 1.0% of a pH balancing agent. The sprayable gel cleaner composition may be completely clear without any suspended encapsulated particles in it and includes a viscosity range from about 200 centipoise to about 30,000 centipoise at standard temperature and pressure.

  • Patent number: 7955649
    Abstract: A method of forming a thin film of amphiphilic molecules on a substrate by using a resealable vial carrier is provided. The method includes placing the substrate in a vacuum chamber. A resealable cap member of the vial carrier is opened. The vial carrier may contain a liquid or solid amphiphilic material. The open vial carrier is placed within the chamber. The chamber is sealed and a pressure from about 2×10+2 to 5×10?6 torr is applied to the chamber. The vial carrier is heated to a temperature between 100-350° C. The amphiphilic material is vaporized in the chamber. A thin film of amphiphilic molecules is formed on the substrate. The chamber is opened and the substrate having the thin film of amphiphilic molecules thereon is removed. The resealable vial carrier includes a temperature resilient vial carrier and a resealable member selectively disposed about an opening of the vial carrier.
