The present invention relates to a new formulation with antimicrobial activity, its use as a cleaning agent or disinfection agent or descaling agent as well as to a cleaning agent
or disinfection agent or descaling agent comprising said formulation.
Antimicrobial formulations are applied in different areas like in home care formulations, in all-purpose-cleaners, in bath-room cleaners, in toilet-bowl cleaners, in disinfectants, in sanitary cleaners and in clean in place (CIP) applications. CIP applications are used
10 in practice in the food and beverage industry, like in breweries, in the dairy industry, in the soft-drink and juice manufacturing industry, but also in the cosmetic and pharma- ceutical industry.
A huge number of biocides are known which have antimicrobial activity, among them
aliphatic carboxylic acids need to be mentioned. Unfortunately important members of the class of aliphatic carboxylic acids with antimicrobial activity suffer from strong smell at least at effective concentrations. Further even though such aliphatic carboxylic acids show some biocidal effectivity their activity could be still enhanced. 20
Beside antimicrobial activity the descaling efficiency in most applications is of im- portance.
Thus the object of the present inventions is to provide a formulation with good antimi- crobial activity and descaling efficiency without unpleasant odour.
The finding of the present invention is to provide a formulation comprising a short chain carboxylic acid, i.e. a carboxylic acid with not more than 10 carbon atoms, and a non- aromatic sulfonic acid compound. 30
Accordingly the present invention is directed to a formulation comprising
(a) a sulfonic acid (SA) of formula (I)
R is selected from the group consisting of linear alkyl residue, branched alkyl res-
35 idue, linear alkenyl residue, and branched alkenyl residue; and
(b) at least one, preferably one, two or three, more preferably one, carboxylic acid (CA) selected from the group consisting of mono-carboxylic acid, di-carboxylic acid and tri-carboxylic acid. 40
The formulation of the present invention has good antimicrobial activity and descaling efficiency without pungent odour.

Accordingly in a further aspect of the invention the formulation as defined herein is used as an antimicrobial, especially as a bactericide and/or a fungicide.
In one embodiment the formulation of the present invention is used for antimicrobial
treatment, antimicrobial accoutrement, desodoration, sanitization and/or disinfection of inanimate surfaces and materials.
In a further aspect the present invention is directed to a product comprising the formu- lation according to this invention, wherein said product is selected from the group con-
10 sisting of home care formulation, disinfectant of hard and/or soft surfaces, sanitary de-
tergent of hard and/or soft surfaces, and product for clean in place application.
