Abstract
Abstract 57 The invention relates to a water-dilutable antimicrobial composition which is characterized by the following ingredients: a) an inorganic and/or organic acid b) acetic acid halogenated in the a-position, c) an unbranched and/or branched aliphatic fatty acid. ! In one preferred embodiment, the antimicrobial composition according to the invention contains the following ingredients: a) a relatively high percentage of a mild inorganic and/or strong organic acid, b) an acetic acid halogenated in the a-position, c) small quantities of an unbranched and/or branched aliphatic fatty acid. The invention also relates to the use of this antimicrobial composition in an aqueous use solution as a combined acidic cleaner and disinfectant.
