Acidic aqueous chlorite teat dip with improved visual indicator stability, extended shelf life, sanitizing capacity and tissue protection

A physically and chemically stable visibly indicated mastitis treatment comprising a combined acidulant part and a chlorite part, the combined mastitis composition can effectively reduce microbial populations on contact with an animal surface for an extended period of time,

• (a) said aqueous acidulant part comprising an activator acid comprising a phosphoric acid, lactic acid, glycolic acid or mixtures thereof, and a chlorine dioxide stable visual indicator system stable in the combined teat dip material;
• and
• (b) said separate chlorite part substantially free of organic component, consisting essentially of an alkali metal 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 a barrier to environmental contamination.

A physically and chemically stable visually indicated mastitis treating composition in an acidulant part and a chlorite part, that can effectively reduce microbial populations, on contact with a teat surface and for an extended period, said composition comprising:

• (a) an aqueous acidulant part comprising:
• (i) about 0.1 to 15 parts by weight of an organic or inorganic acid, or salts thereof, or mixtures thereof, the acid selected from the group consisting of a phosphoric acid, lactic acid, glycolic acid;
• (ii) a rheology modifier comprising about 0.01 to 10 parts by weight of a pseudoplastic thickener;
• (iii) a visual indicator system that can retain color stability for at least 24 hours in the presence of chlorite or chlorine dioxide;
• (iv) about 0.1 to 15 parts of an emollient;
• (v) a major proportion of water;
• and
• (b) a chlorite part consisting essentially of an alkali metal chlorite salt;
• wherein the composition exhibits rheology that promotes cling to immobilize the composition on the teat surface and provides a barrier to environmental contamination.
