    Abstract: A dispenser for petroleum distillate based household products, such as furniture oil, baby oil, or the like, comprises a non-pressurized spray bottle comprising a reduced volume spray apparatus which dispenses less than about 0.8 ml per actuation, and a removal resistant neck closure which does not permit closure removal or easy opening of the container. Lower risk is also obtained by addition of a thixotropic thickener to the petroleum distillate based product, to provide a product having a viscosity of greater than 100 SUS at rest at 100° F., but which exhibits shear-thinning, so as to be capable of being dispensed as a spray or fine mist by a non-pressurized spray dispenser or pump. Still further risk lowering may be attained by the addition of an effective amount of a bittering or aversion agent so as to substantially discourage voluntary ingestion of the petroleum distillate based product.

  • Cleaning method for polyethylene terephthalate containers
    Patent number: 6554005
    Abstract: A method for cleaning polyethylene terephthalate containers including contacting the PET container with an alkaline wash solution having a temperature ranging of less than about 60° C. is disclosed. The alkaline wash solution is formulated from a first concentrate, a second concentrate, an alkalinity source, and a balance of water. The first concentrate preferably has a first nonionic surfactant, a first builder, and acid in an amount effective to provide a phase stable solution. The second concentrate preferably has a second nonionic surfactant and a second builder. The first and second concentrate are present in the wash solution in a concentration ranging from about 0.3 wt. % to 2.0 wt. %. Preferably, the first nonionic surfactant has a cloud point ranging from about 5° C. to 60° C.
