Patent number: 8188204Abstract: 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.Type: GrantFiled: March 24, 2011Date of Patent: May 29, 2012Assignee: Rhodia Inc.Inventors: Vance Bergeron, Dominic Wai-Kwing Yeung, Jean-Francois Bodet, Mark Robert Sivik, Bernard William Kluesener, William Michael Scheper

Publication number: 20120118590Abstract: 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.Type: ApplicationFiled: November 17, 2010Publication date: May 17, 2012Inventor: James A.

Publication number: 20120103639Abstract: 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.Type: ApplicationFiled: October 28, 2011Publication date: May 3, 2012Inventors: Alvin Rains, Shan L. Rains
