Low-tack surface anti-microbial coating composition and method of application

A barrier-forming composition for a surface treatment comprising:

• a carbohydrate gum, a humectant, and an antimicrobial agent;
• wherein the barrier-forming composition meets the following requirements:
• about 0.0001%≦C≦about 0.4%;
• about 0.07%≦H≦about 70%;
• and
• 0.0005%<A
• or
• about 0%≦C≦about 0.4%;
• about 55%≦H≦about 70%;
• and
• 0.0005%<A
• wherein all percentages are by weight of the total composition;
• wherein C is the carbohydrate gum;
• H is the humectant;
• and A is the antimicrobial agent;
• and
• the barrier composition is active to trap, and neutralize or kill microorganisms.

A method for trapping, and neutralizing or killing microorganisms that cause infectious disease, the method comprising:

• applying a barrier-forming composition that comprises an antimicrobial onto a surface of an apparatus;
• forming a barrier coating on the surface of the apparatus that is active to trap and kill or neutralize microorganisms encountered by the barrier layer for a duration of at least about one hour thereby preventing or decreasing the risk of infection from the microorganisms;
• wherein the barrier-forming composition further comprises a humectant and a gum, the gum being present in an amount of about 0.0001% to about 0.4% by weight of the total barrier-forming composition;
• wherein the pH of the barrier-forming composition is about 5.5 to about 8;
• wherein the barrier-forming composition has a viscosity of about 400 cps or less.
