  • Publication number: 20120172439
    Abstract: The present disclosure provides methods for generating percarboxylic acid compositions and/or peroxycarboxylic acid compositions formed external to a point of use in non-equilibrium reactions for use in certain bleaching and antimicrobial applications, in particular laundry applications. The compositions are generated external to a point of use, at alkaline pH levels, viz. greater than about pH 12, and optionally suitable for use with detergents and/or surfactants for synergistic bleaching efficacy. Methods of bleaching and/or disinfecting are further provided.

  • Patent number: 6699510
    Abstract: The mastitis control teat dip composition having a visible indicator aspect of the invention provides a softening, soothing, smoothing, relaxing property, a rapid initial kill, a useful highly pseudoplastic rheology, a barrier/film-forming capacity, a unique antimicrobial composition that is stable over an extended period of time, and unexpected long term microbial control when compared to the prior art materials disclosed in patents and used in the marketplace. The indicator aspect provides ease of visually detecting the material on the animal skin and can indicate efficacy of the material. The compositions of the invention are made by combining an aqueous liquid composition containing the visual indicator combined with the organic components which can be combined with a simple aqueous solution of a salt of chlorous acid, preferably an alkali metal chlorite.
