  • Patent number: 6867233
    Abstract: Acidic antimicrobial compositions for treating food surfaces and food contact surfaces comprise an organic acid and a surfactant, said composition having a pH of from about 2 to about 5. Concentrated, acidic antimicrobial compositions preferably comprise a stabilizing agent to prevent precipitation of the surfactant upon dilution of the concentrated composition. Methods of use comprise contacting food surfaces or food contact surfaces with the compositions of the present invention. Articles of manufacture comprise a container, an acidic antimicrobial composition, and a set of instructions in association with the container.
    Type: Grant
    Filed: February 27, 2001
    Date of Patent: March 15, 2005

  • Patent number: 5041230
    Abstract: Polymeric soil release agents that have high viscosities when molten are difficult to process. Certain organic materials can be added to such agents to lower the viscosity and improve processing. Examples of such organic materials include fatty acids, some nonionic ethylene glycol derivatives, polyethylene or polypropylene glycols and their short alkyl chain ethers, certain polyhydroxy and alkyl ether solvents, and aryl ethers of propylene glycol.
