  • Patent number: 8211838
    Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.

  • Publication number: 20120083434
    Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.

  • Patent number: 7745381
    Abstract: A method for lubricating the passage of a conveyor comprising applying an undiluted lubricant composition through non-energized nozzles to at least a portion of the conveyor, the lubricant composition comprising a silicone emulsion and a water-miscible lubricant, the lubricant composition having a viscosity of less than 40 centipoise when measured using a Brookfield viscometer with an RV2 spindle at a spindle speed of 20 RPM and the lubricant composition being substantially free of a triethanolamine salt of dodecyl benzene sulfonic acid.

  • Publication number: 20090196939
    Abstract: A method for antimicrobial treatment (e.g. antimicrobial treatment of food packaging and equipment) comprising applying to microbes a composition containing a diluting solvent (e.g., water), an antimicrobially-active solvent having a density different from the density of the diluting solvent, and an optional cosolvent, surfactant, or additional antimicrobial agent, wherein the amount of antimicrobially-active solvent or additional antimicrobial agent is sufficiently high and the amount of cosolvent or surfactant is sufficiently low so that the composition will provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C. Preferred methods of the invention employ compositions containing an additional antimicrobial agent such as peroxyacetic acid. Compositions for use in the method can be prepared as concentrates, and used full strength or in diluted form.
