Abstract
Description
[0001] The present invention relates to antimicrobial compositions, their use as antimicrobial agents, and formulations comprising the antimicrobial compositions.
[0002] Preservation of household formulations and cosmetic formulations extends their shelf life and thus provides consumers with better value for money.
[0003] In addition, preservatives prevent consumers from spreading microorganisms throughout their homes or onto their bodies and thus provide health benefits. Antimicrobial agents are well described in the art and many antimicrobial agents with excellent properties are available.
[0004] However, there is a desire to provide a range of advanced preservation systems that provide excellent antimicrobial performance and also keep the content of antimicrobial actives to a minimum. For example, many well-known antimicrobial actives with excellent efficacy are not preferred due to reduced consumer acceptance, health concerns or due to regulatory restrictions. The content of such actives may also be restricted (legally) for the same reasons. In addition, it is desirable that all elements of the preservation system meet sustainability goals and ensure that household formulations and cosmetic formulations are as environmentally friendly as possible.
[0005] Accordingly, there is a need to provide more advanced preservation systems that provide excellent antimicrobial action and are also highly acceptable to consumers, do not raise health or regulatory concerns, and have excellent sustainability and environmentally friendly properties.

Dissolve the sample completely in the acetylation mixture, stirring and heating if necessary. Add 5 ml of the catalyst solution (catalyst solution: Dissolve 2 g of 4-dimethylaminopyridine in 100 ml of pyridine). Close the reaction vessel and place it in a water bath, pre-heating to 55 °C for 10 minutes while stirring. Then add 10 ml of completely deionized water to the reaction solution, close the reaction vessel again and react the mixture in the water bath once more, shaking for 10 minutes. Then cool the sample to room temperature (25 °C). Then add 50 ml of 2-propanol and 2 drops of phenolphthalein.

[0051]
[0052] OHV = hydroxyl value in mg KOH / g of substance
[0053] Va = volume in ml of the aqueous sodium hydroxide solution consumed during the titration of the sample
[0054] Vb = volume in ml of the aqueous sodium hydroxide solution consumed during the titration of the efficacy
[0055] c = molar concentration of the aqueous sodium hydroxide solution in mol / l
[0056] t = titer of the aqueous sodium hydroxide solution

[0232] Additional surfactants
[0233] In at least one embodiment, the liquid laundry detergent formulation contains surfactants selected from anionic surfactants, nonionic surfactants, and mixtures thereof; preferably the surfactants are selected from linear alkylbenzene sulfonates, alkyl ether sulfates, nonionic surfactants, amine oxides, and betaines; and more preferably from linear alkylbenzene sulfonates, alkyl ether sulfates, and nonionic surfactants.

[0235] Additional optional ingredients
[0236] Household cleaning formulations may contain one or more optional ingredients. For example, they may contain conventional ingredients commonly used in detergent compositions, especially laundry detergent compositions. Examples of optional ingredients include, but are not limited to, synergists, bleaches, bleach-active compounds, bleach activators, bleach catalysts, optical bleaches, dye transfer inhibitors, color protectants, anti-redeposition agents, dispersants, fabric softeners and antistatic agents, optical brighteners, enzymes, enzyme stabilizers, foam regulators, defoamers, deodorants, preservatives, disinfectants, hydrotropes, fiber lubricants, anti-shrinkage agents, buffers, fragrances, processing aids, colorants, dyes, pigments, corrosion inhibitors, fillers, stabilizers or other conventional ingredients for washing or laundry detergent compositions.
[0237] Polymer
[0238] To enhance detergency, it can be advantageous to use polymers in household cleaning formulations, especially in liquid laundry detergent formulations. The polymer is preferably polyalkoxylated polyethyleneimine (EPEI). Polyethyleneimine is a material composed of ethyleneimine units -CH2CH2NH-, and when branched, the hydrogen on the nitrogen is replaced by a chain of additional ethyleneimine units. These polyethyleneimines can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc. Specific methods for preparing these polyamine backbones are disclosed in US 2,182,306, US 3,033,746, US 2,208,095, US 2,806,839 and US 2,553,696.
[0239] Household cleaning formulations, especially liquid laundry detergent formulations, may contain other polymeric materials, such as: dye transfer inhibiting polymers, anti-redeposition polymers or cotton soil release polymers, especially those based on modified cellulose materials. In particular, when EPEI is absent, the formulation may additionally contain a polymer of polyethylene glycol and vinyl acetate, such as the lightly grafted copolymer described in WO 2007 / 138054. Such amphiphilic graft polymers based on water-soluble polyoxyalkylene as the graft base and side chains formed by the polymerization of vinyl ester components have the ability to reduce the surfactant content while maintaining a high level of removal of oily soil.
[0240] Hydrotrope
[0241] In at least one embodiment, the formulation comprises a hydrotrope. As used herein, a "hydrotrope" is neither water nor a conventional surfactant, but rather a solvent that aids in solubilizing surfactants and other components, particularly any polymers and / or chelating agents, in a liquid to render it isotropic. Hydrotropes are particularly useful in household cleaning formulations. Among suitable hydrotropes are the following: monopropylene glycol (MPG), glycerol, sodium cumenesulfonate, ethanol, other diols such as dipropylene glycol, diethers, and ureas. MPG and glycerol are preferred hydrotropes.

In at least one embodiment, the enzyme is selected from proteases, mannanases, pectin lyases, cutinases, esterases, lipases, amylases, cellulases, and combinations thereof. Sub-preferred additional enzymes may be selected from peroxidases and oxidases. The enzyme is preferably present together with a corresponding enzyme stabilizer. The total enzyme content in the formulation is preferably from 0 wt% to 5 wt%, more preferably from 0.5 wt% to 5 wt%, and still more preferably from 1 wt% to 4 wt% of the total weight of the formulation.
[0244] Chelating agent
[0245] The formulation, particularly a household cleaning formulation, preferably comprises a chelating agent. Preferred chelating agents include, for example, organic phosphonates, alkane hydroxy phosphonates, and carboxylates that can be obtained from Thermphos under the trademark DEQUEST. The preferred chelating agent content is less than 10 wt% and preferably less than 5 wt% of the total weight of the formulation. A particularly preferred chelating agent is, for example, HEDP (1-hydroxyethylidene-1,1-diphosphonic acid) sold as Dequest2010. Also suitable is 2066 (diethylenetriamine penta(methylene-phosphonic acid) or DTPMP heptasodium).
[0246] Buffer
[0247] In at least one embodiment, the formulation, particularly a liquid laundry detergent formulation, comprises a buffer. The buffer is preferably present to control the pH, in addition to any reagents optionally included for the generation of anionic surfactants from, for example, LAS or fatty acids. Feasible buffers are one or more ethanolamines, such as monoethanolamine (MEA) or triethanolamine (TEA). They are preferably used in the formulation in an amount of from 1.0 wt% to 15 wt%. Other suitable amino alcohol buffer materials may be selected from compounds having a molecular weight greater than 61 g / mol, which includes MEA. In addition to the materials already mentioned, suitable materials also include: monoisopropanolamine, diisopropanolamine, triisopropanolamine, monoaminohexanol, 2-[(2-methoxyethyl)methylamino]-ethanol, propanolamine, N-methylethanolamine, diethanolamine, monobutanolamine, isobutanolamine, monopentanolamine, 1-amino-3-(2-methoxyethoxy)-2-propanol, 2-methyl-4-(methylamino)-2-butanol, or mixtures thereof. A feasible alternative to the amino alcohol buffer is an alkali metal hydroxide such as sodium hydroxide or potassium hydroxide.

[0259] The examples which follow are intended to illustrate the subject-matter of the invention without restricting it thereto. Example
[0260] Material
[0261] Flex is commercially available from Clariant. Chemical name: Capryloyl / hexanoyl anhydrous methyl glucamide (and) water, active content: 70% by weight. Capryloyl / hexanoyl anhydrous methyl glucamide is a mixture of a compound of formula (I) wherein R is -(CH2)8CH3 and a compound of formula (I) wherein R is -(CH2)6CH3.
[0262] SC is commercially available from Clariant. Chemical name: Sorbitan octanoate.
[0263] CGE is commercially available from Clariant. Chemical name: Caprylyl Glyceryl Ether.
[0264] 4-Hydroxyacetophenone is commercially available from Sigma Aldrich.
[0265] Example 1
[0266] The antimicrobial properties of Velsan Flex, 4-hydroxyacetophenone, and their combination against bacteria, yeasts, and molds were studied: To test the inhibition against bacteria, Velsan Flex, 4-hydroxyacetophenone, or their combination was diluted in butyl polyethylene glycol and added to liquid Caso-Agar at different concentrations at 50 °C and buffered to pH 7 (+ / -0.2). To test the inhibition against yeasts and molds, Velsan Flex, 4-hydroxyacetophenone, or their combination was diluted in butyl polyethylene glycol and added to liquid Sabouraud-4% Dextrose-Agar at different concentrations at 50 °C and buffered to pH 5.6 (+ / -0.2). Each solution was poured into Petri dishes and inoculated with the same amount of bacteria, yeast, or mold respectively. The minimum inhibitory concentration (MIC) is the lowest concentration of each composition that inhibits the growth of each microorganism, where the next lowest dilution does not inhibit the growth of the microorganism. The experiments were conducted under scientifically fair conditions so that appropriate comparisons and conclusions could be drawn.
[0267] The results are shown in the following table:
[0268]
[0269] It can be seen that since the MIC of the combination is lower than that of the single component, the combination of the two components shows a synergistic effect. This effect was observed in a broad spectrum of microorganisms including both bacteria and fungi. This leads to the advantages that a smaller amount of a single preservative can be used to preserve formulations such as cosmetic formulations or household formulations, reducing the likelihood of negative effects from antimicrobial actives, and saving resources.
[0270] The antimicrobial properties of Velsan SC, 4-hydroxyacetophenone, and their combination against bacteria, yeasts, and molds were studied in experiments similar to those described above.
[0271] The results are shown in the following table:
[0272]
[0273]
[0274] It can be seen that since the MIC of the combination is lower than that of the single component, the combination of Velsan SC and hydroxyacetophenone shows a synergistic effect. This effect was observed in a broad spectrum of microorganisms including both bacteria and fungi. This leads to the advantages that a smaller amount of a single preservative can be used to preserve formulations such as cosmetic formulations or household formulations, reducing the likelihood of negative effects from antimicrobial actives, and saving resources.
[0275] Example 2
[0276] Antiseptic ability demonstrated in challenge tests:
[0277] The synergistic effect and ability to preserve typical cosmetic formulations for wash-free applications are also shown. The following examples show the challenge test results according to Chapter 5.1.3 of the 10th Edition of the EUROPEAN PHARMACOPOEIA. The following test bacteria are used as representative microorganisms: Pseudomonas aeruginosa (Gram-negative bacterium, abbreviated as "P.a."), Staphylococcus aureus (Gram-positive bacterium, abbreviated as "S.a."), Escherichia coli (Gram-negative bacterium, abbreviated as "E.c."), Candida albicans (yeast, abbreviated as "C.a.") and Aspergillus brasiliensis (mold, abbreviated as "A.b.").
[0278] Standard A represents the recommended efficacy to be achieved. In reasonable cases where Standard A cannot be achieved, for example due to an increased risk of negative reactions, Standard B must be met. Standard A is associated with excellent protection of the formulation, and Standard B requires showing sufficient protection but requires the application of additional risk elimination measures related to packaging and raw material quality. In the case where any of the tested organisms is Standard F, the entire challenge test fails and the antiseptic / protection of the formulation is insufficient.
[0279] The unpreserved samples of each formulation were also tested as a reference. A formulation difficult to preserve was used as the test system:
[0280] Wash-free: O / W-cream gel
[0281]
[0282] The results of the challenge tests of the formulations tested at pH 7 are shown in the following table:
[0283]
[0284] The non-preserved test system failed the challenge test for all test bacteria at pH 7 (item 7). The use level of 0.5% hydroxyacetophenone was insufficient to preserve the formulation as it failed to resist E.c. (item 6) and only reached the B-standard for S.a. Additionally, Velsan SC, Velsan Flex, or Velsan CGE alone was insufficient to preserve the formulation (items 8 - 11). In contrast, the combination of Velsan Flex and hydroxyacetophenone at use levels of 0.5% and 0.5% (item 1) reached the A-standard for all test microorganisms, providing excellent protection for the formulation. The same formulation also reached the A-standard for all test bacteria at pH 7 when using 0.5% and 0.5% of Velsan SC and hydroxyacetophenone (item 2), providing excellent protection for the formulation. The same effect was observed when using a combination of 0.25% and 0.5% use levels of Velsan CGE with hydroxyacetophenone, reaching the A-standard for all microorganisms (item 4). The combination of 0.5% Velsan CGE with hydroxyacetophenone could even reduce the amount of hydroxyacetophenone to 0.25% (item 3), resulting in the A-standard for all test microorganisms. However, when using 0.25% hydroxyacetophenone as the sole preservative, only the F-standard was obtained for all test microorganisms (item 5).
[0285] As can be seen from the results shown in Example 2, the combination of hydroxyacetophenone with Velsan Flex, Velsan SC, or Velsan CGE showed a synergistic effect, because when the use concentration of hydroxyacetophenone was 0.5%, it could already pass the challenge test, while hydroxyacetophenone alone or Velsan Flex, Velsan SC, or Velsan CGE was insufficient to fully protect the cosmetic formulation at this concentration. This leads to the advantage that a smaller amount of preservative can be used to preserve formulations such as cosmetic formulations or household formulations, reducing the likelihood of negative effects from antimicrobial actives.
