Abstract
Disinfectant with colorizer as positive visual indicator of its application to skin, such as udders of milking animals, especially those whose milk production is BST-stimulated, to preclude mastitis. Iodine-free aqueous solution of a permanganate as colorizer and a hypochlorite as disinfectant, buffered to pH of 9 to 10, is applied to udder, especially to the teats, in post-milking step. Removal of residual color is enabled by acidic peroxide solution also similarly useful to decolorize any permanganate-colored animal or human skin.

An iodine-free aqueous antimicrobial composition adapted to disinfect an udder of a milk animal, whose milk production may be somatotropin-stimulated, and to color it for at least a part of the time between successive milkings, comprising an aqueous disinfectant having a pH between about 9 and 10, including compatible colorizer.
An iodine-free aqueous antimicrobial composition adapted to disinfect an udder of a milk animal, whose milk production may be somatotropin-stimulated, and to color it for at least a part of the time between successive milkings, comprising an aqueous hypochlorite disinfectant buffered to a pH between about 9 and 10, including a compatible inorganic colorizer.
For application to animal or human skin, a disinfectant indicator, comprising an iodine-free colorizing disinfectant containing a hypochlorite as disinfectant and a permanganate as colorizer;
- the purplish resulting indicating color being persistent but removable by subsequent application of a weakly acidic aqueous peroxide solution.
