Stable ready-to-use dosage forms containing coloring matter and active chlorine, and methods of making and using same as disinfectants

A method of producing a colored disinfectant by mixing in a liquid a solid or semi-solid dosage form containing an organic chloroxidizer together with coloring matter which will produce a colored appearance in the resultant product without affecting the stability of the chloroxidizer;

• said coloring matter being in its maximal level of oxidation;
• said organic chloroxidizer having a pH of 4-8 and acting as a chlorine donor releasing active chlorine in the liquid containing the coloring matter without affecting the colored appearance of the liquid over a period of time.

A method of indicating, by color, which surface or biological tissue, such as teats of a milking animal, or skin area before a medical procedure, has been treated with a disinfecting liquid, cream, ointment, paste, or gel, by applying to said surface or biological tissue a formulation containing an organic chloroxidizer having a pH of 4-8 and acting as a chlorine donor of active chlorine, together with a coloring matter;

• said coloring matter being in its maximal level of oxidation.

A method of coloring a disinfectant product, wherein a maximally oxidized substance is used as a coloring matter in conjunction with an organic chlorine donor.

A colored disinfectant liquid, cream, ointment, paste, or gel comprising a solid or semi-solid formulation dissolved in a solvent and containing an organic chloroxidizer acting as a chlorine donor releasing active chlorine, and coloring matter added thereto;

• said coloring matter being in its maximal level of oxidation;
• said chloroxidizer with coloring matter having a pH of 4-8 and being present in a sufficient quantity to disinfect or sterilize a surface, vessel, or tissue as required while the liquid, cream, ointment, paste, or gel stably maintains its colored appearance over a period of time which exceeds the period of time that the resultant product liquid would normally be used for that purpose.
