  • Patent number: 6596684
    Abstract: A granular detergent component comprising a high level of surfactant, for example, cationic surfactant, and an inorganic carrier material is prepared by a process involving spraying an aqueous solution of the surfactant onto moving granules of the inorganic carrier material in the presence of a drying gas, preferably air, at a temperature within the range of from 65 to 200° C. The process is preferably carried out in a fluidised bed. Preferred inorganic carrier materials are sodium carbonate and zeolite MAP.

  • Patent number: 6596677
    Abstract: Propylene carbonate based cleaning compositions. The compositions comprise propylene carbonate, a glycol ether, water, and an acid activator. The compositions may optionally also comprise hydrogen peroxide. The present invention also provides for a method of removing a soil from a hard surface, wherein a cleaning composition comprising propylene carbonate, a glycol ether, water, and an acid activator is applied to the hard surface. After application of the cleaning composition, the soil is removed from the hard surface without the exertion of mechanical force.

  • Patent number: 6583103
    Abstract: A liquid two part cleaning composition for hard surfaces, and a two chamber bottle for dispensing the cleaner are disclosed. The cleaner includes a first basic liquid and a second acidic liquid. At least one of the liquids includes a surfactant system. At least one of the liquids includes a foam inhibitor. When the first and second liquid are dispensed on a surface, carbon dioxide gas released instantaneously creates a quickly breaking foam on the surface. The bottle has horizontal orientation, of the first and second chamber that assures a user's thumb is on the front wall and a user's fingers are on the rear wall of the bottle when dispensing. The horizontal orientation provides an ergonomically advantageous wide range of motion. The positioning of a user's thumb on the front wall of the bottle allows for design adjustments in the bottle to achieve equal dispensing from both chambers.

  • Publication number: 20030109390
    Abstract: The present invention is directed to new and improved solutions for packaging contact lenses and to methods for treating contact lenses with such solutions to improve the comfort of the lenses during wear. In particular, the present invention is directed to packing solutions comprising certain non-ionic surfactants containing a poly(oxyalkylene) copolymer and having a molecular weight of 4000 to 30,000. Such surfactants are retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, thereby providing significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.
