Patent ID: RE41279

Claim:
A physically and chemically stable, visibly indicated, mastitis treatment composition that can effectively reduce microbial populations on contact with an animal skin for an extended period, said composition comprising a blended combination comprising: (a) an aqueous acidulant part comprising an activator acid, a rheology modifier or a pseudoplastic thickener, a chlorine dioxide stable visual indicator system selected from the group consisting of: (i) about 0 . 05 - 30 wt % of urea and about 0 . 001 - 10 wt % of a colorant, based on the weight of the blended composition; and (ii) comprising about 0.001-50 wt %, based on the weight of the blended composition combination , of a dispersed oil phase, wherein said oil phase contains about 0.001-50 wt % of an oil-soluble dye, based on the weight of said oil phase, and said oil phase is uniformly dispersed in a fine particle size in the blended composition combination and a major proportion of water; and (b) a chlorite part substantially free of organic component, consisting essentially of comprising an alkali metal chlorite salt; wherein the composition exhibits a visual indicator for a period of at least 24 hours and the composition comprises a rheology that promotes cling to immobilize the composition on the animal skin surface and provides thereby providing a barrier to environmental contamination.
