  • Antimicrobial composition useful for the treatment of bovine mastitis
    Patent number: 6582734
    Abstract: The present invention relates to a two-part antimicrobial composition comprising at least one chlorine dioxide generating component comprising at least one metal chlorite and at least one acid-forming compound in a solid carrier, and at least one liquid aqueous component. The composition further comprises at least one antimicrobial fatty acid having from about 2 to about 15 carbon atoms, and preferably from about 6 to about 12 carbon atoms. The components, upon mixing, form a composition having a pH in the range of about 5 to about 10.

  • Acidic aqueous chlorite teat dip providing shelf life sanitizing capacity and tissue protection
    Patent number: 6436444
    Abstract: The mastitis control teat dip composition of the invention provides 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 compositions of the invention are made by combining an aqueous thickened liquid composition containing the organic components which can be combined with a simple aqueous solution of a salt of chlorous acid, preferably an alkali metal chlorite. The materials can be combined, blended into a smooth viscous material and can be immediately contacted with the target animals. The .compositions of the invention provide rapid initial kill, consistent long term kill and chemical and rheological stability.

  • Acidic aqueous chlorite teat dip with improved emollient providing shelf life, sanitizing capacity and tissue protection
    Patent number: 6379685
    Abstract: The mastitis control teat dip composition 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 compositions of the invention are made by combining an aqueous thickened liquid composition containing the organic components which can be combined with a simple aqueous solution of a salt of chlorous acid, preferably an alkali metal chlorite. The materials can be combined, blended into a smooth viscous material containing an emollient package and can be immediately contacted with the target animals. The compositions of the invention provide rapid initial kill, consistent long term kill and chemical and rheological stability.
