Technical Field
Disinfecting compositions are disclosed comprising a synergistic combination of a benzyl-substituted quaternary ammonium compound and specified polymers. The specified polymers increase the disinfection activity of the benzyl-substituted quaternary ammonium compound in the disinfecting composition.
Background
Industry leaders have predominantly utilized quaternary ammonium compounds (quats) in order to provide consumers with a germ kill benefit. Quats are typically cheap, readily available, and offer a satisfactory level of disinfection to the consumer. Despite these benefits, quats are known to be toxic to aquatic environments with potential long-lasting effects. Even though quats are expected to biodegrade, regulatory bodies (e.g., the US Environmental Protection Agency) may prohibit individuals from making biodegradability claims if these compounds are present in any amount.

Detailed Description
Disinfecting compositions are disclosed comprise a synergistic combination of a benzyl-substituted quaternary ammonium compound and a specified polymer. The disclosed compositions comprise a low concentration of quat, but are still able to obtain germ kill.
The disclosed compositions comprise a benzyl-substituted quaternary ammonium compound. Benzyl-substituted quaternary ammonium compounds have the formula: C6I-15CH2NR3+X-, wherein each R is independently a C1-C18 hydrocarbon group and X is an alkali metal, saccharinate group, or carbonate group. Preferably the benzyl-substituted quaternary ammonium compound has the formula C6H5CH2N(CH3)2R+X-, wherein R is a C12-C18 or C12-C16 alkyl group and X is Cl.
The polymer is selected from the group consisting of poly(diallyldimethylammonium chloride) (PQ6) having a molecular weight <100kDa (PQ6 <100kDa); PQ6 having a molecular weight ranging from 200kDa to 300 kDa (PQ6 200- 300kDa); PQ6 having a molecular weight ranging from 400 kDa to 500 kDa (PQ6 400500 kDa); copolymers of vinylpyrrolidone (VP) and quaternized vinylimidazole (QVI)(PQ16) having 5%wt VP and 95% wt QVI (PQ16 5VP-95QVI); PQ16 having 50%wt VP and 95% wt QV! (PQ16 50VP-50QVI); Poly(2-dimethylamino)ethyl methacrylate) methyl chloride quaternary salt (PQ37); 1-propanaminium, N,N,N-trimethy1-3-[(1-oxo-2- propenyl)amino] chloride, homopolymer (A1000); 1-dodecanaminium, N,N-dimethyl-N- [3-[(2-methy1-1-oxo-2-propen-1-ybamino]propy1]-, chloride (1:1), polymer with sodium 2-methy1-2-[(1-oxo-2-propen-1-yhamino]-1-propanesulfonate (1:1) and N,N,N-trimethy1-3-[(1-oxo-2-propen-1-y0amino]-L propanaminium chloride (1:1) (C113); and combinations thereof.
The concentration of the benzyl-substituted quaternary ammonium compound is approximately 5% wt to approximately 50% wt less than the concentration of the benzylsubstituted quaternary ammonium compound in a comparative disinfecting composition comprising the benzyl-substituted quaternary ammonium compound alone, preferably approximately 6% wt to approximately 40% wt less, more preferably approximately 7% wt to approximately 30% wt less, even more preferably approximately 8% wt to approximately 20% wt less, and more preferably approximately 9% wt to approximately 15% wt less.
To achieve germ kill with the low level of quat, the disclosed composition comprise a polymer, as defined above.
The combination of benzyl-substituted quaternary ammonium compound and specified polymer may comprise all the ingredients necessary for germ kill. As a result, the disclosed compositions may be substantially free of any other known germ kill actives. In other words, the disclosed compositions do not include any additional quaternary ammonium compounds, such as dialkyl dimethyl ammonium chloride. The benzyl-substituted quaternary ammonium compound is the only quat used in the disclosed compositions. Multiple quaternary ammonium species may help achieve sanitization and/or provide better breadth of germ kill. As a result, most commercial sanitizers include a blend of two or more quaternary ammonium compounds.
Applicant believes that using the benzyl-substituted quaternary ammonium compound as the only quat provides an improved safety profile as compared to products containing two or more quaternary ammonium compounds. In vitro epiderm assays were performed on four different compositions containing: (a) 3.70% wt BKC alone, (b) 5.90% wt BKC alone, (c) 5.90% wt blend of BKC and dodecyl dimethyl ammonium chloride (DDAC), and (d) 3.70% wt blend of BKC and DDAC. The results for (a) and (b) were "non-corrosive." The results for (d) were "borderline." The results for (c) were "Corrosive." Applicant was surprised to discover that less damaging results were achieved from concentrations of BKC that are the same or even higher than the concentrations of a combination of BKC and DDAC.
The disclosed compositions are also substantially free of peroxides, such as hydrogen peroxide or peracids. The disclosed compositions are also substantially free of guanides, such as bisguanide. The disclosed compositions are substantially free of alkali metal hypochlorites. The disclosed compositions are substantially free of isocyanurates. The disclosed compositions are also substantially free of borates, such as boric acid or perborates.
The disclosed compositions may further comprise water, preferably soft water.
Soft water comprises less than 17 ppm of calcium and magnesium. The disclosed compositions may comprise approximately 80%wt to approximately 97.5% wt water. As a result the disclosed compositions may be a liquid, preferably a single phase liquid. The disclosed compositions may further comprise customary ingredients typically included in disinfecting compositions, such as anionic surfactants, non-ionic surfactants, organic acids and their salts, chelants, thickeners, pH adjusters, opacifiers, enzymes, non-aqueous solvents, fragrances, dyes, and the like.
Alternatively, the disclosed compositions may be substantially free of non-ionic surfactants. Specially, the disclosed compositions may be substantially free of betaine surfactants. The disclosed compositions may also be substantially free of unsaturated fatty alcohols.
The disclosed compositions may be substantially free of anionic surfactants, such as alkyl sulfates and alkyl ether sulfates.
The disclosed compositions may be substantially free of enzymes.
The disclosed compositions may be substantially free of alkanolamine, such as monoethanolamine, diethanolamine, triethanolamine, or combinations thereof.
The disclosed compositions may be substantially free of non-aqueous solvents, such as glycol ethers. The disclosed compositions may also be substantially free of added alcohols, such as ethanol. One of ordinary skill in the art will recognize that the benzyl-substituted quaternary ammonium compounds are frequently supplied in an alcohol or glycol solvent. However, more of these solvents are not deliberately added to the disclosed compositions.
The disclosed compositions may be substantially free of an added electrolyte, such as sodium chloride.
The disinfecting composition may be used to disinfect hard or soft surfaces. For example, the disinfecting may be used in all-purpose cleaners or hard surface disinfectants, such as triggers, dilutables, or wipes. Alternatively, the disinfecting composition may be used in laundry products, such as laundry biocides, laundry sanitizer, laundry softeners, laundry conditions, laundry fabric protectors, or any combination thereof. Preferably, the disclosed laundry compositions may serve two or more functions.
For example, the disclosed laundry composition may be a fabric protector and biocide, or a fabric protector and sanitizer, or a softener and biocide, or a softener and sanitizer, or a conditioner and biocide, or a conditioner and sanitizer. Alternatively, the disclosed laundry composition may be a fabric protector and softener and conditioner. Alternatively, the disclosed composition may be a biocide and sanitizer.
Contrary the disclosures in the prior art and as shown in the examples that follow, not all polyquaternium polymers behave in the same manner. Indeed, a large quantity of some polyquaternium polymers would be needed to increase the efficacy of BKC. And BKC is inexpensive. As a result, these polyquaternium polymers may be undesirable to use to increase the germ kill of benzyl-substituted quaternary ammonium compounds, especially if they are toxic to aquatic environment. As a result, the disclosed compositions may be substantially free of a polyquaternium polymer selected from the group consisting of poly(acrylamide-co-diallyldimethylammonium chloride (PQ7), copolymers of vinylpyrrolidone and quaternized vinylimidazole having more vinylpyrrolidone units than quatemized vinylimidazole units (PQ16 70VP-30QVI), 2-pyrrolidinone, 1-ethenyl-polymer with N,N,N-trimethy1-3-[(2-methy1-1-oxo-2-propenyl)amino]-1-propanium chloride (PQ28), and combinations thereof. Based on the chemical structure and to be confirmed by testing, Applicant believes that P033 would perform worse antimicrobially than PQ37 and would also be undesirable for use in the teachings herein.
Methods are disclosed for reducing a concentration of a benzyl-substituted quaternary ammonium compound in a disinfecting composition while maintaining the germ kill efficacy of the disinfecting composition by adding a polymer to the disinfecting composition. In other words, the concentration of a benzyl-substituted quaternary ammonium compound in a disinfecting composition may be reduced as compared to a comparative disinfecting composition comprising the benzyl-substituted quaternary ammonium compound alone by adding a first polyquaternium polymer to the disinfecting composition.
As shown in the example that follows, the concentration of benzyl-substituted 30 quaternary ammonium compounds may be reduced when specific polymers are added to the formulation and still provide equivalent germ kill to compositions containing higher concentrations of the benzyl-substituted quaternary ammonium compounds. Benzylsubstituted quaternary ammonium compounds are known to be toxic to aquatic environments. The ability to reduce the concentration of the benzyl-substituted quaternary ammonium compound is therefore beneficial. Additionally, the formulation does not require a large percentage of these polymers, which helps contain formulations costs. The polymer is selected from the group consisting of poly(diallyldimethylammonium chloride) (PQ6) having a molecular weight <100kDa (PQ6 <100kDa); PQ6 having a molecular weight ranging from 200kDa to 300 kDa (PQ6 200-300kDa); PQ6 having a molecular weight ranging from 400 kDa to 500 kDa (PQ6 400- 500 kDa); copolymers of vinylpyrrolidone (VP) and quaternized vinylimidazole (QVI)(PQ16) having 5%wt VP and 95% wt QVI (PQ16 5VP-95QVI); PQ16 having 50%wt VP and 95% wt QVI (PQ16 50VP-50QVI); Poly(2-dimethylamino)ethyl methacrylate) methyl chloride quaternary salt (PQ37); 1-propanaminium, N,N,N-trimethy1-3-[(1-oxo-2-propenyl)amino] chloride, homopolymer (A1000); 1-dodecanaminium, N,N-dimethyl-N- [3-[(2-methyl-1-oxo-2-propen-1-y0amino]propyl]-, chloride (1:1), polymer with sodium 2-methyl-2-[(1-oxo-2-propen-1-yDamino]-1-propanesulfonate (1:1) and N,N,N-trimethy1-3-[(1-oxo-2-propen-1-y0amino]-L propanaminium chloride (1:1) (C113); and combinations thereof.

Example 1 -BKC PQ Antimicrobial Svnerav Inoculum preparation: Take well-defined and typical colonies of Staphylococcus epidermidis from a recent plate of tryptic soy agar (TSA), dissolve and vortex them in a tube containing 30mL of tryptic soy broth (TSB) and incubate for 17+/-1h at 37°C+/-1°C. Quantify by plate count in TSA (incubated for 48h+/-1h at 37°C+/-1°C). Use the broth culture suspension within seven (7) days after the incubation period. Vortex and take 0.2mL from the broth culture and dilute in appropriate volume of 0.85% NaCI to normalize the strain at 3-5x10"5 CFU/mL Test sample gradient creation: Using a micropipette, add 100pL of TSB in a 96-well microtiter plate format. Dispense 100pL of the test sample (polymer) in column 1 (from row A to row H depending on the number of test samples) and 100pL of the same test sample (polymer) in column 2 in their respective rows within 30 minutes of preparing the solution if it has been previously diluted. (both samples are the same) Using a micropipette take 100pL of the sample from column 2 and dilute it in column 3 performing a 1:1 dilution with the diluent already present in the wells, proceeding with a serial dilution up to column 9. Discard the remaining 100 pL.
Inoculum: Within 30 minutes of preparing the gradient and inoculum bacterial suspension, dispense 20 pL of a solution of BKC in the wells from columns 2 to 9. Dispense 100 pL of inoculum using a micropipette into each well in columns 2 to 10. Columns 1 and 11 are the sample sterility test and negative test control columns, respectively. No growth should be observed in these columns. Column 10 is the positive test control and growth should be observed.
To test the polymers antimicrobial activity alone (without BKC) repeat the steps above, without the addition of the 20 pL solution of BKC.
The inoculum must be between 2.5 -4.5 x 10^5 CFU/mL in each well.
Incubate the microwell plate for 24h+/-1h at 37°C+/-1°C.
The minimum inhibitory concentration (MIC) is determined by visually checking the wells for growth. The MIC is defined as the minimal concentration of polymer in the corresponding well without visible growth after 24 hours of incubation. The tests were performed two times for most of the listed polyquaternium polymers. The MIC of BKC alone ranged from 5-8 ppm or 0.3-0.8 ppm in R&D test conditions. One of ordinary skill in the art will recognize that micro testing is not an exact science and results may vary significantly, especially in R&D test conditions. However, these results demonstrate the consistent synergy or lack of synergy between BKC and the polymers. The results are provided in Table 1:

The combinations permit the disclosed disinfecting concentrations to significantly reduce the quantity of BKC without adding a large quantity of the polymer to the disinfecting compositions.
PQ16 50VP-50QVI and PQ37 also demonstrate synergy, but require a larger quantity of polymer to do so.
PQ7, PQ16 70VP-30VPI and PQ28 require a large quantity of polymer to increase the efficacy of BKC. And BKC is inexpensive. As a result, these polyquaternium polymers may be undesirable to use to increase the germ kill of benzyl-substituted quaternary ammonium compounds, especially if they are toxic to aquatic environment.
Example 2 -Antimicrobial Activity The antimicrobial efficacy of the formulations in Table 2 was determined using AS-1-M F.22714-16 entitled the Standard Test Method for Evaluation of Laundry Sanitizers and Disinfectants (version 15 April 2.016). A greater than 3-login reduction of all organisms (Klebsiella pneumoniae, Staphylococcus aureus) on both the test fabric swatch & simulated wash water for a contact time of 1 to 60 minutes (determined by product specification) at a testing temperature ranging from 4°C to 60°C+1.0°C (determined by product specification) is required to pass the ASTM E2274-16 for a sanitization product. For a disinfecting product, total kill must be achieved. Additional and optional contact times, temperatures, and test organisms may be used.
Microorganisms were subcultured on Nutrient Agar A (through at least one daily transfer), incubating at 35 ± 2°C. On the day prior to testing, the slant was washed and cells transferred into French square bottles containing 20 mL of solidified Nutrient Agar B. The cells were then incubated between 18 to 24 hours at 35 ± 2°C, agar side down.
Growth was then removed using 3-mL dilution fluid and 5 sterile glass beads to suspend the growth. Cultures were then standardized to yield approximately 108 CFUs per mL of S. aureus and 108 CFUs of K. pneumoniae.
The tests were performed using "clean" experimental conditions, which means no organic soil load was included for this test method. For laundry sanitizers/softeners, the desired experimental conditions are "clean conditions" because the laundry sanitizer/softener is used after a laundry detergent in a laundry washing process, i.e. on clean laundry.
As the test is designed to simulate killing bacteria on fabric, the test fabric also needs to be prepared. 300g of test fabric was boiled for 1 hour in 3L of deionized water containing 1.5g NaCO3 and 1.5g nonionic wetting agent. The fabric was then rinsed in boiling water, then in cold water, until there was no longer the appearance of foam. The fabric was then air dried for 24 hours at room temperature. Once dry, the fabric was cut into 2 inch strips, weighing 15 ± 0.1 grams each. The fabric was then secured onto a stainless steel spindle & wrapped precisely 12 times & then secured (as to represent laundry ballast). Furthermore, 1 by 1.5 inch fabric swatches were cut from the remaining fabric & used as carriers for microorganisms. At least 3 carriers were prepared for each organism tested. On the day of testing, these carriers were inoculated with 0.030 mL of prepared inoculum, taking care to distribute evenly across the 1 by 1.5 inch swatches.
Swatches were dried in a 35 ± 2°C incubator for no longer than 30 minutes, and were used within 1 hour of drying. When ready, they were to be placed between the 6th and 7th folds of the simulated ballast, without any overlap of the swatches.
Experimentally, a 1:315 dilution of test substance was prepared in hard water (400 ppm CaCO3) within 3 hours of testing. Approximately 150 mL of this test substance (simulated rinse water) was used to submerge the fabric carrier & ballast in a sterile exposure chamber that is agitated for the desired contact time. The test was allowed to proceed for 25 minutes and then the simulated rinse water and fabric carriers were separately neutralized. The carriers were then plated, and both plates/tubes are incubated for 48±2 hours at 35±2°C. The results were evaluated for sanitization (in terms of logo reduction) or for disinfection (positive or negative result for growth).

The results also suggest that BKC alone is performing better (or at least the same as) a blend of BKC and DDAC. Finally, these results demonstrate that the concentration of BKC can be lowered by addition of P037 (E2 and E4) and still obtain germ kill equivalent to that obtained from a higher concentration of BKC (El).
For context, it is typically observed in the ASTM 2274 method that meeting success criteria on the swatch is more challenging than in the wash water. This is likely due to mobility of the active agents and their ability to penetrate deep into the simulated ballast to reach the inoculated fabric carriers. Inversely, the simulated rinse water is similar to a solution, where there is little interference between the active substance and any particles suspended therein.
Example 3 -Micro Efficacy Synergies -PQ6 The antimicrobial efficacy of the formulations in Table 3 was determined using ASTM E2274-16 entitled the Standard Test Method for Eva nation of Laundry Sanitizers and Disinfectants (version 15 Atari: 2016), as described in Example 2.

By adding 0.4% active amount of PQ6 to Formula E7, we were able to reduce the quat by 0.7% and to achieve a similar micro result. Formula E8 also shows a significant improvement in micro efficacy as we reduced the quat by 0.25% and added 0.4% PQ6 compared to Formula E6. Because many quats used for germ kill can add corrosivity or environmental hazards to a product, finding synergies such as PQ6 can lead to better optimized formulations.
