    Abstract: The present invention refers to a laundry pre-treatment composition capable of treating hydrophobic and organic particulate soils in the laundry item, the composition comprising: (a) an effective soil treating amount of a hydrophilic ethoxylate surfactant composition having an HLB of about 10 to 20, the surfactant comprising the formula R1-(OC2H4)o-(OC3H6)n-OH with an HLB of at least 10, wherein m and n are independently a number of about 0 to about 20, n+o > 4 and R1 is an aromatic or aliphatic, hydrophilic group of 6 to 24 carbon atoms; and (b) an effective soil treating amount of a hydrophobic alcohol ethoxylate composition of the formula: R2-(OC2H4)p-OH with an HLB of less than about 9 wherein R2 is a straight or branched chain fatty alkyl group containing from about 6 to 24 carbon atoms and p is a number of less than about 2; wherein the amounts of ethoxylate surfactant composition and the alcohol ethoxylate composition are selected to obtain an overall HLB value of about 7 - 12 in the composition.

    Abstract: A method for antimicrobial treatment (e.g. antimicrobial treatment of food packaging and equipment) comprising applying to microbes a composition containing a diluting solvent (e.g., water), an antimicrobially-active solvent having a density different from the density of the diluting solvent, and an optional cosolvent, surfactant, or additional antimicrobial agent, wherein the amount of antimicrobially-active solvent or additional antimicrobial agent is sufficiently high and the amount of cosolvent or surfactant is sufficiently low so that the composition will provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C. Preferred methods of the invention employ compositions containing an additional antimicrobial agent such as peroxyacetic acid. Compositions for use in the method can be prepared as concentrates, and used full strength or in diluted form.
