Abstract:
A physically and chemically stable mastitis treating composition that can effectively reduce microbial populations, on contact with a teat surface and for an extended period, said composition being pseudoplastic and comprising:(a) an acidulant part comprising: (i) about 0.1 to 15 weight percent of an antimicrobial sulfonic acid, salt thereof, or mixtures thereof; (ii) about 0.1 to 15 weight percent of an acid, salt thereof, or mixtures thereof, the acid selected from the group consisting of phosphoric acid and lactic acid; (iii) about 0.01 to 10 weight percent of a rheology modifier comprising either a pseudoplastic thickener comprising a polysaccharide or an inorganic thickener selected from the group consisting of silicate, silica and clay; (iv) about 0.01 to 8 weight percent of a film forming agent comprising a polymer selected from the group consisting of polyvinyl alcohol, polyvinyl acetate and mixtures thereof, and (v) a major proportion of water; and (b) a chlorite part, substantially free of an organic component, consisting essentially of an alkali metal chlorite salt; wherein the composition exhibits effective antimicrobial action lasting at least a week without dermal irritation of the animal, a stable pseudoplastic rheology that promotes cling to immobilize the composition on the teat surface and provides a barrier to environmental contamination.
