Systems and methods for spraying of sanitizing or disinfecting compositions with improved compatibility

A dilute hypohalite sanitizing or disinfecting composition for use in a dispensing system for dispensing the dilute hypohalite sanitizing or disinfecting composition, wherein the dispensing system includes a nozzle through which the aqueous hypohalite sanitizing or disinfecting composition is dispensed during use, and a tubing for conveying the aqueous hypohalite sanitizing or disinfecting composition from a reservoir to the nozzle, the dilute hypohalite sanitizing or disinfecting composition comprising:

• (a) water;
• and
• (b) a hypohalite at a concentration from 85 ppm to 500 ppm;
• (c) wherein the hypohalite composition has a pH of no more than 8;
• (d) wherein the dilute hypohalite composition exhibits at least a 65% recovery of hypohalite after 24 hours of contact between the hypohalite composition and the tubing of the dispensing system and wherein the tubing comprises one or more materials selected from the group consisting of:
• fluorinated ethylene propylene and plasticizer free PVC and any combinations thereof;
• (e) wherein the aqueous hypohalite sanitizing or disinfecting composition maintains a concentration of hypohalite of less than about 200 ppm as dispensed.

• (a) water;
• and
• (b) a hypohalite at a concentration from 150 ppm to 200 ppm;
• (c) wherein the hypohalite composition has a pH of no more than 8;
• (d) wherein the dilute hypohalite composition exhibits at least a 65% recovery of hypohalite after 24 hours of contact between the hypohalite composition and the associated tubing of the dispensing system wherein the associated tubing has a stiffness from 120 lbf/in to 135 lbf/in and a compression force to closure of from 20 lbf to 30 lbf;
• (e) wherein the aqueous hypohalite sanitizing or disinfecting composition maintains a concentration of hypohalite of about 85 ppm to 200 ppm as it is dispensed.
