Antimicrobial sanitizing composition containing n-alkyl and n-alkenyl succinic acid and methods for use. An antimicrobial sanitizing composition concentrate suitable for use in food preparation and handling equipment and capable of being diluted with a major amount of diluent and the resulting aqueous use solution.


The concentrate containing:

(a) a dicarboxylic acid having the general formula: ##STR1## wherein R is a saturated or unsaturated hydrocarbon moiety having two carbon atoms; R' is a substituted or unsubstituted n-alkyl or n-alkenyl moeity having between about 6 and about 12 carbon atoms, and R" is a functional group selected from the group consisting of hydrogen, alcohols, amines and sulfates;

EXAMPLE I

Decyl succinic acid(cas:110-15-6) was prepared from decyl succinic anhydride by thermal hydrolysis. Two solutions of decyl succinic acid(cas:110-15-6) were prepared. A quantity of 75 percent phosphoric acid was added to one of the decyl succinic acid(cas:110-15-6) solutions such that the resulting solution contained 1 percent decyl succinic acid(cas:110-15-6) and 15 percent phosphoric acid. The remaining decyl succinic acid solution contained 1 percent succinic acid with no additives.


A one-part sample of the acidified decyl succinic acid(cas:110-15-6) solution was admixed with 100 parts of water having 500 ppm synthetic water hardness present as calcium carbonate to yield a solution containing 100 ppm decyl succinic acid(cas:110-15-6). The resulting senitizing solution was exposed to challenge bacteria Staphylococcus aureaus ATCC 6538 and Escherichia coli ATCC 11229 to determine antimicrobial effectiveness. The test procedure employed was the Germicidal and Detergent Sanitizer Test recommended by the Association of Official Analytical Chemists. The test was carried out at 77° F. and the results are found in Table I.


A 50 ppm sample and a 25 ppm sample of the diluted acidified decyl succinic acid(cas:110-15-6) solution were prepared by admixing 0.5 part and 0.25 part samples of acidified 1 percent decyl succinic acid(cas:110-15-6) solutions, respectively, with 100 parts water containing 500 ppm hardness present as calcium carbonate (CaCO3). The samples were exposed to the challenge bacteria E. coli and Staph. aureus, according to the A.O.A.C. test procedures outlined above. The results are found in Table I.
A sample containing 100 ppm of the non-acidified decyl succinic acid(cas:110-15-6) sample was also prepared using water having 500 ppm hardness and was exposed to the challenge bacteria. The resulting data is also found in Table I.
As can be seen from the data in Table I, the decyl succinic acid(cas:110-15-6) solution exhibited bacteriocidal activity under acidic conditions.
