1. A method for aseptic packaging of food, beverages or pharmaceuticals comprising:
- (a) contacting a package with a composition consisting essentially of a wetting agent, and an antimicrobial agent, wherein the wetting agent consists essentially of;
(i) a sheeting agent, wherein the sheeting agent comprises at least one compound having the structure represented by formula I;
R—

(CH2CH2O)n—
Hwherein R is a (C1-C12) alkyl group, and n is an integer in the range of 1 to 100;
(ii) a defoaming agent comprising a polyoxypropylene-polyoxyethylene block copolymer surfactant;
(iii) an association disruption agent of a C12-C14 fatty alcohol propylene oxide surfactant; and
(iv) an additional ingredient selected from the group consisting of a carrier, a hydrotrope, a chelating/sequestering agent, and combinations thereof;
(b) filling the package with a substance selected from the group consisting of food, beverage, pharmaceutical, and combinations thereof; and
(c) sealing the package.

Abstract
The present invention is directed to wetting agent compositions and methods for making and using the wetting agent compositions. The compositions of the invention include a sheeting agent, a defoaming agent, and an association disruption agent. The wetting agent compositions of the present invention result in a faster draining/drying time on most substrates compared to conventional wetting agents. The wetting agent compositions of the present invention are especially suitable for use on plastic substrates.
