Antibacterial agents and compositions, methods and systems employing same

FIELD OF THE INVENTION

[0002] The present invention relates to antibacterial agents, more particularly salicylanilide substituted compositions, preferably monosubstituted salicylanilide compositions, most preferably monohalogenated salicylanilide compositions, useful in antibacterial compositions, bacteria-reducing systems, antibacterial products and bacteria-reducing methods.

BACKGROUND OF THE INVENTION

[0003] Consumers are very conscientious about cleanliness and/or sanitization, especially when it comes to dishes, utensils, tableware, cookware, and cleaning articles, such as sponges, wash cloths, etc.. that are typically found and/or used in kitchens and bathrooms at home and away from home, such as in restaurants. Other areas of interest are textiles, fabrics and garments that come into contact with consumers. Accordingly, there is a need for a bacteria-reducing system and method that sanitizes such articles, such as garments, textiles, sponges, dishes, tableware, and wash cloths.

[0004] The prior art is replete with detergent compositions containing multi-halogenated salicylanilides, especially tribromosalicylanilide and tetrachlorosalicylanilide; see U.S. Pat. Nos. 2,906,711; 3,968,210; 3,989,827; and 4,061,603; German #2,157,209; and British #848,306.

[0005] The art teaches that salicylanilides, when used individually, are not effective against gram negative bacteria, only gram positive bacteria (Natarajan et al., 1992, Indian Drugs 29:545-552). Additionally, the art teaches that, in a detergent matrix, mono-halogenated salicylanilides are ineffective; multi-halogenated salicylanilides are required for efficacy. In fact, the art teaches that mono-halogenated salicylanilides are not efficacious in a detergent matrix (Lemair et al., 1961, J. Pharmaceutical Sciences, 50:831-837) with the exception of monohalogenation on the aniline ring of thiosalicylanilides (British patent #1,088,498). The mono halogenated thiosalicylanilides in British #1,088,498 were taught to be effective only against gram-positve bacteria, not against gram-negative bacteria.

[0006] Although multi-halogenated salicylanilides are effective in a detergent matrix, these compounds have not enjoyed widespread use due to a variety of reasons, including but not limited to problems encountered in formulating these agents. Accordingly there remains a need for an effective means of formulating salicylanilide type compounds, as well as a need for derivatives that are effective against both gram positive and gram negative bacteria.

Examples of the preferred dialkyl quaternary compounds are di(C8-C12)dialkyl dimethyl ammonium chloride, such as didecyldimethylammonium chloride (Bardac 22), and dioctyldimethylammonium chloride (Bardac 2050). Typical concentrations for biocidal effectiveness of these quaternary compounds range from about 0.001% to about 0.8%, preferably from about 0.005% to about 0.3%, more preferably from about 0.01% to about 0.2%, and even more preferably from about 0.03% to about 0.1%, by weight of the usage composition. The corresponding concentrations for the concentrated compositions are from about 0.003% to about about 2%, preferably from about 0.006% to about 1.2%, and more preferably from about 0.1% to about 0.8% by weight of the concentrated compositions.

[0215] Nonlimiting examples of suitable organic acids that can be used in the compositions of the present invention include citric, malic, succinic, and benzoic, which, when used in suitable concentrations, as further described herein, are highly efficacious against microbes, such as Salmonella choleraesuis and Staphylococcus aureus. When used in the presence of a surfactant, preferably a nonionic surfactant such as alcohol ethoxylates (for example, ALFONIC® 810-6 Ethoxylated available from Vista Chemical Company in Houston, Tex.), these acids were found to have effective residual antimicrobial activity against a variety of microbes, including gram negative (−) bacteria, such as Salmonella choleraesius, and gram positive (+) bacteria, such as Staphylococcus aureus. In general, the water soluble carboxylic acids useful in accordance with the invention have the following structure:

R—COOH

[0216] wherein R may be represented by: lower alkyl; substituted lower alkyl; hydroxy lower alkyl (e.g. HOCH2—); carboxy lower alkyl (e.g. HOOC—CH2—CH2—); carboxy, hydroxy lower alkyl (e.g., HOOCCH2 CHOH—); carboxy, halo lower alkyl (e.g. HOOCCH2CHBr—); carboxy, dihydroxy lower alkyl (e.g. HOOC—CHOH—CHOH—); dicarboxy, hydroxy lower alkyl (e.g. HOOC—CH2C—C(OH)(COOH) H2—); lower alkenyl, carboxy lower alkenyl (e.g. HOOCCH═CH—); dicarboxy lower alkenyl (e.g. HOOC—CH2C(COOH)═CH—); phenyl (C6 H5—); substituted phenyl (e.g. hydroxy phenyl HO—C6 H4—). Other acid examples include hydroxy lower alkyl e.g. lactic; carboxy. hydroxy lower alkyl, e.g. 2-methyl malic; carboxy, halo lower alkyl, e.g. 2-chloro-3-methyl succinic; carboxy, dihydroxy lower alkyl. e.g. 2-methyl tartaric; dicarboxy, hydroxy lower alkyl, e.g. 2-methyl citric acid; and carboxy lower alkenyl, e.g. fumaric. The above definitions are used in an illustrative but not a limiting sense. The term “lower” as used herein refers to an acid wherein “R” contains one to six carbon atoms. The term “substituted” indicates that one or more hydrogen atoms are substituted by halogen atoms (F, Cl, Br, I) hydroxyl groups, amino groups, thiol groups, nitro groups, cyano groups, and the like. Examples of preferred antimicrobial organic acids include, but are not limited to, citric acid, lactic acid, malic acid, salicylic acid, acetic acid, and mixtures thereof.

[0217] In a preferred embodiment, the compositions comprise organic acid at a level of from about 0.5% to about 20%, more preferably from about 1% to about 10%, and still more preferably from about 1.5% to about 7.5% by weight of the antimicrobial composition. Citric acid is a highly preferred organic acid having antimicrobial action. Citric acid is preferred because it is a natural acid and is relatively safe for use on household surfaces, especially surfaces used for food preparation such as countertops in kitchens and dining rooms. In addition, when citric acid is allowed to remain on a surface, it tends to provide a glossy or shiny film on the surface which can be aesthetically satisfying to consumers and provide a visual signal to consumers that the surface has residual antimicrobial protection. Also, the glossy film allows the consumer to identify areas on the hard surface which were inadvertently missed in treating the surface and allows the consumer to verify that an entire area has been treated.

[0218] Bacteria

[0219] The substrates/articles used in accordance with the present invention contain bacteria. The bacteria may be any bacteria known to those skilled in the art.
