Low foaming acid-anionic surfactant sanitizer compositions

The anti-microbial sanitizer composition consisting essentially of a mixture, based on 100 parts by weight thereof, of:

• 5 to 25 parts of
• a. anti-microbial anionic surfactant or a mixture of anti-microbial anionic surfactants including a normally high foaming anionic surfactant, selected from the group consisting of C.sub.1 -C.sub.18 -alkyl-benzene sulfonic acid, salts thereof and mixtures of said acid or salts with an alkyl- or alkenyl-phenoxy benzene disulfonic acid, naphthalene sulfonic acid, alkyl- or alkenyl-naphthalene sulfonic acid;
• 30to 50 parts of
• b. an acid selected from the group consisting of phosphoric acid, hydrochloric acid, hydroxyacetic acid, sulfuric acid, diglycolic acid, lactic acid, acetic acid and sulfamic acid;
• 2 to 15 parts of
• c. a C.sub.8 -C.sub.18 -aliphatic alcohol, a C.sub.9 -C.sub.12 -alkylphenol or mixture thereof;
• and
• 0.5 to 10 parts of
• d. a trivalent compound of iron and aluminum selected from the group consisting of ferrous aluminum sulfate, aluminum sulfate and aluminum hydroxide;
• said components (c) and (d) being compatible in said composition and present in amounts sufficient to reduce foam formation in said composition compared to the foam formation which occurs in the absence of said (c) and (d) components.
