Abstract
Anhydrous sanitizing and disinfecting concentrate compositions having excellent shelf life and chemical stability comprise less than 0.1 weight percent water; an anionic surfactant present in an amount of from about 0.05 weight percent to about 10.0 weight percent, and an acidic component, present in an amount effective to produce a pH of below pH 5.0 upon dilution with water. Between about 0.25 parts by weight to about 7.5 parts by weight of the concentrate compositions are diluted with sufficient water to make 100 parts by weight of an aqueous solution having excellent antimicrobial activity against gram positive and gram negative bacteria.
