Abstract
A lubricant composition comprising a lubricating agent and a quaternary phosphonium compound is useful as a conveyor, container or beverage lubricant.
Claims28
A container or a conveyor for a container, whose surface is coated at least in part with a lubricant composition comprising a lubricating agent and an antimicrobial effective amount of a quaternary phosphonium compound.
A process for lubricating a container, comprising applying to at least a portion of a surface of the container, a lubricant composition comprising a lubricating agent and an antimicrobial effective amount of a quaternary phosphonium compound.
A process for lubricating a conveyor, comprising applying to at least a portion of the conveyor, a lubricant composition comprising a lubricating agent and an antimicrobial effective amount of a quaternary phosphonium compound, and then moving a container on the conveyor.
A lubricant composition comprising a lubricating agent and an antimicrobial effective amount of a quaternary sulfonium or quaternary iodonium compound.
A lubricant composition comprising a phosphate ester lubricating agent and an antimicrobial effective amount of a quaternary phosphonium compound.
A lubricant composition comprising a fatty acid lubricating agent and an antimicrobial effective amount of a quaternary phosphonium compound.
A lubricant composition comprising an amine lubricating agent and an antimicrobial effective amount of a quaternary phosphonium compound.
A lubricant composition comprising a quaternary phosphonium compound and a quaternary ammonium compound.
A method of preventing or reducing stress cracking of polyethylene terephthalate containers comprising treating the container with a lubricating composition comprising a lubricating agent and a quaternary phosphonium compound.
A beverage lubricant comprising a quaternary phosphonium compound.
A lubricant composition comprising a quaternary phosphonium compound and one or more of an oxidizing antimicrobial agent and a non-oxidizing antimicrobial agent.
A lubricant composition comprising about 0.5 to about 25 weight percent of a phosphonium compound, about 0.1 to about 20 percent by weight of a fatty acid, about 1 to about 50 percent by weight of a phosphate ester, a neutralizing agent in an amount effective to provide the composition with a pH of about 3 to about 9.5, about 0.5 to about 30 percent by weight of a nonionic surfactant, and water as a carrier, the percents based on the total weight of the composition.
A lubricant composition comprising 2 to 10 weight percent of a phosphonium compound, 0.5 to 7 percent by weight of a fatty acid, 5 to 25 percent by weight of a phosphate ester, a neutralizing agent in an amount effective to provide the composition with a pH of 5.5 to 7.5, 2 to 10 percent by weight of a nonionic surfactant, and water as a carrier, the percents based on the total weight of the composition.
An object or a conveyor for an object, whose surface is at least temporarily coated at least in part with a lubricant composition comprising a lubricating agent and an antimicrobial effective amount of a quaternary phosphonium compound.
