  • Patent number: 8188204
    Abstract: The present invention relates to a polymeric material comprising units capable of having a cationic charge at a pH of from about 4 to about 12; provided that said polymeric material has an average cationic charge density from about 2.75 or less units per 100 daltons molecular weight at a pH of from about 4 to about 12. The polymeric material is a suds enhancer and a suds volume extender for hand dishwashing compositions and personal care products such as soaps, shaving cream foam, foaming shaving gel, foam dephiliatories and shampoos. The polymers are also effective as a soil release agent in fabric cleaning compositions. The polymers are also useful in agrochemical foam, fire-fighting foam, hard surface cleaner foam, and coagulant for titanium dioxide in paper making.

  • Publication number: 20120118590
    Abstract: A fire-extinguishing composition has a water-thickening agent and a foaming agent. The fire-extinguishing composition contains less than 10 vol % water. The ratio of water-thickening agent to foaming agent is from 99:1 to 1:99 volume ratio. The composition is in the form of a powder or flake. A method of extinguishing a fire is by applying a mixture of a fire-extinguishing composition and water to a fire, the fire-extinguishing composition having a water-thickening agent and a foaming agent.

  • Publication number: 20120103639
    Abstract: An improved fire extinguishing, suppressing, and preventing mixture, method, and system for various classifications of fires which exhibits superior characteristics to knock down the fire, helps to prevent flash and re-ignition, and contains only a trace amount of fluorochemicals. When the mixture is spread on burning surfaces, including fuel and other liquid surfaces, the agent suppresses vaporization, extinguishes flames and helps to suppress re-ignition and reflash of the fire. The mixture is friendly to the environment. It causes no harmful reaction to a burn victim and aids in cooling the victim to slow the burning of skin. The mixture can be washed off a bum victim with soap and water. Other embodiments are described herein.

  • Publication number: 20110308821
    Abstract: A method of manufacturing a fire-extinguishing agent for a fire extinguisher and a fire extinguishing apparatus is provided. The fire-extinguishing agent is manufactured by dissolving 55 g to 65 g of diammonium hydrogen phosphate in 300 to 350 mL of hot water at 70° C. to 90° C. to prepare a solution, dissolving 6 g to 8 g of ammonium sulfate in the prepared solution, dissolving 170 g to 190 g of potassium carbonate in the resultant solution, and adding, to the resultant solution, 25 to 35 mL of the undiluted solution of an aqueous film-forming foam fire-extinguishing agent. The total amount of the fire-extinguishing agent is adjusted to 600 mL. A throw-type fire extinguisher having a total weight of 700 g to 800 g is produced by charging a container with 600 mL of the fire-extinguishing agent.
