Claims38
A method for sanitizing a surface comprising:
- applying to a surface a composition comprising:
- (1) a C5 to C22 fatty acid selected from the group consisting of pentanoic acid, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid, lauric acid, and salts thereof;
- and
- (2) a source of alkalinity selected from the group consisting of hydroxides, carbonates, bicarbonates, amines, and mixtures thereof,
- wherein the composition does not comprise glycerol esters, and
- wherein the composition has a pH of 8.5 or greater and provides 3-log reduction against gram positive bacteria, gram negative bacteria, and yeasts within 1 minute at 50° C.

A method for sanitizing a surface comprising:
- diluting a concentrate composition to form a use solution, wherein the concentrate composition is diluted at a ratio of about 1:100 to about 1:1500 of concentrate to water;
- applying to a surface the use solution, the concentrate composition comprising:
- (1) about 20 wt. % to about 90 wt. % of a C5 to C22 fatty acid selected from the group consisting of pentanoic acid, hexanoic acid, heptanoic acid, octanoic acid, nonanoic acid, decanoic acid, undecanoic acid, dodecanoic acid, lauric acid, and salts thereof;
- and
- (2) a cationic amino/ester, cationic amino/amide, or salt thereof,
- wherein the composition provides 3-log reduction against gram positive bacteria, gram negative bacteria, and yeasts within 1 minute at 50° C.
