  • Method and composition for reducing the degradation rate of agrochemicals in storage
    Patent number: 5733478
    Abstract: A method for reducing the rate of degradation of stored agrochemicals, particularly pesticides, is provided which essentially involves incorporating a stabilizing compound into the agrochemical in preparation for storage, with the stabilizing compound selected from the group consisting of a diol and a triol. In the preferred embodiment, a pesticide having the active ingredient METASYSTOX.RTM. has an improved shelf life with the addition of about 2 parts by weight of propylene glycol to about 25 parts by weight of METASYSTOX.RTM..

  • Method for suspending particulates in liquids and products resulting therefrom
    Patent number: 5573769
    Abstract: A method for coating finely divided particles with one or more hydrophobic materials, such as waxes, in order to envelope each particle with a thin layer of material that entraps air adhering to the surface of the particle. Because of the entrapped air, the apparent density of the particles is decreased and their stability in aqueous suspensions is greatly improved. When applied to pesticides, this process produces mixtures that remain substantially in suspension for several hours after agitation, thus allowing more uniform and trouble-free application.

  • Simulated rawhide product
    Patent number: 4419372
    Abstract: A chewable, digestible, high protein product for canine pets which has physical properties and appearance resembling rawhide is prepared by extruding a mixture of an oil seed protein, a polyol plasticizer, lecithin and water, and impacting the surface of the extrudate with a stream of particles until the leather-like appearance is obtained.
