Definitions

  • the present invention relates to the use of a composition comprising an alkyd resin and an organic solvent for the repeated sanitizing or cleansing of a surface.
  • UV- radiation ultraviolet radiation
  • silver ions or copper ions to solutions and surfaces in order to reduce the microbiological contamination.
  • GB 1 575 007 A relates to a surfactant composition for heavy duty cleaning applications. It discloses a composition comprising an alkyd resin, a solvent, such as a glycol ether, and synthetic sea water for the cleaning application.
  • aqueous solutions comprising alcohols, such as iso-propanol, hydrogen peroxide or NaOCl.
  • the disinfection of a surface with an aqueous solution of, for example, hydrogen peroxide or iso-propanol has the disadvantage that the effect is of only very short duration because the hydrogen peroxide decomposes and the iso-propanol evaporates. After decomposition or evaporation of the disinfectant, the surface can again be contaminated with, for example, bacteria. This requires a frequent disinfection of the surface and it always remains the risk that between two disinfection cycles the surface becomes contaminated and potentially does not have the required low level of bacteria or other microorganisms.
  • alkyd resins provide antimicrobial properties to a surface. While this provides a good long-term effect, there remains the problem that the alkyd resin should preferably be applied to an already disinfected surface, which requires an additional disinfectant and a further disinfection step prior to the coating of the surface with the alkyd resin layer.
  • the present inventors combined the known immediately acting disinfectants with alkyd resin compositions.
  • alkyd resin compositions it turned out that if such combined composition is repeatedly applied to a surface, an increasing alkyd resin layer is retained on the surface. The thickness of this layer increases with each disinfection cycle and after some time, increases to an extent which can make the surface unsuitable for the intended purpose. Removing such alkyd resin layer can be quite cumbersome and makes a mere combination of usual disinfectants with an alkyd resin composition undesirable for a repeated disinfection of a surface.
  • the present inventors found that, if the alkyd resin is combined with certain organic solvents, it is possible to provide a composition which, when applied to a surface, exhibits an immediate antimicrobial effectivity and leaves an alkyd resin layer on the surface, which provides a long-term antimicrobial effect, but when the composition is applied repeatedly to the same surface, the thickness of the alkyd resin layer does not increase.
  • the term "sanitizing” is characterized by the ability to deter, render harmless, destroy and/or exert a controlling effect on all forms and/or parts of microbial life (e.g. bacteria, viruses, fungi, spore forms, etc.); and/or by the ability to remove and/or reduce offensive and/or unpleasant scents. "Sanitizing” therefore includes an antimicrobial effect.
  • cleaning is characterized by the ability to remove dirt.
  • the term "repeated" is to be understood as describing an action which is repeated at least two times, preferably at least three or four times, more preferably at least five, six of seven times, and even more preferably at least eight, nine or ten times, in particular at least ten times.
  • a time span of a few seconds such as, for example, 5 seconds, 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds or 60 seconds.
  • the time span between two repetitions of the action can, however, be considerably longer as, for example, 30 minutes, 1 hour, 2 hours, 6 hours, 12 hours, 1 day, 1 week, or even longer.
  • the time span between the repetition of two actions is at least as long as it requires for the organic solvent to evaporate.
  • antimicrobial refers to the ability of the composition to kill microorganisms.
  • microorganism includes bacteria, viruses, fungi and algae.
  • microorganism refers to bacteria and viruses.
  • biofouling refers to the ability to prevent or remove biofouling on wetted surfaces.
  • Biofouling is the accumulation of microorganisms, plants, algae or animals on wetted surfaces and killing such microorganisms, including algae, supports the prevention or removal of biofouling.
  • surface includes surfaces of bodies of any material, including for example polymers, metal, glass and stone, as well as coatings on such bodies.
  • the bodies may have any shape including for example plates, sheets, fibers and tubes.
  • alkyd resin refers to a polyester modified by the addition of fatty acids and optionally other components. Alkyd resins are derived from a di-, tri- or polyol and a di-, tri- or polycarboxylic acid or carboxylic acid anhydride. The monomers as such are not encompassed by the term "alkyd resin”.
  • the di-, tri- or polyacid can for example be selected from the group consisting of oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, cebacic acid, maleic acid, fumaric acid, glutaconic acid, malic acid, aspartic acid, glutamic acid, tartaric acid, phthalic acid, isophthalic acid, terephthalic acid and/or mixtures thereof.

  • the polyester backbone in the alkyd resin can be modified by any other organic residue, preferably a hydrophobic residue, more preferably a hydrophobic residue which does not contain any additional reactive functional groups as defined below.
  • fatty acid refers to a carboxylic acid having an aliphatic chain.
  • the aliphatic chain is saturated.
  • the aliphatic chain is unsaturated.
  • the number of C-atoms in the aliphatic chain can be in the range from 6 to 40 C-atoms, preferably 6 to 26 C-atoms or 6 to 18 C-atoms. Even more preferably the number of C-atoms in the aliphatic chain is at least 10 or at least 15. More preferably the number of C-atoms in the aliphatic chain is in the range of 6 to 40, 6 to 26, 6 to 20, 10 to 40, 10 to 26, 10 to 20, 15 to 40, 15 to 26 or 15 to 20; 15 to 20 being particularly preferred.

  • the alkyd resin is a branched polyester containing fatty-acid side groups.
  • a branched polyester, as defined herein is a tri-, tetra-, or higher functional molecule and has three, four, or more reactive sites. Branched polyester may form, as linear polyester, molecular chains, but, in addition, branching connections are formed, which result in a three-dimensional network (cross-linking).
  • the composition used in the present invention comprises an organic solvent being selected from methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol, tert-butanol, ethyl methyl ketone, acetone, ethyl acetate, and mixtures thereof.

  • additives in the composition are for example fatty acids, in particular those as described above, oct-1-en-3-ol, citronellal and pheromones of clothing binding, such as for example (Z, E)-tetradeca-9,12-dienyl acetate.
  • the amounts of alkyd resin and organic solvent in the composition used in the present invention are not particularly limited and may be selected by the person skilled in the art according to the requirements. It was, however, surprisingly found that when applying the composition of the present invention repeatedly to a surface, an equilibrium between the built-up of the thickness of the alkyd resin layer and the removal of the alkyd resin layer adjusts and that it is possible to tailor this equilibrium by the ratio of alkyd resin to organic solvent in the composition. The higher the amount of alkyd resin relative to the amount of organic solvent in the compositions is, the thicker the alkyd resin layer will be on the surface after repeated use of the composition until the equilibrium has been adjusted.
  • the composition comprises from 1 to 99 % by weight of the alkyd resin and from 1 to 99 % by weight of the organic solvent, each based on the total weight of the composition.

  • the composition may consist of the alkyd resin and the organic solvent.
  • the composition may comprise further components, such as the above described oil. If the composition contains components further to the alkyd resin and the organic solvent, the weight ratio of the alkyd resin to the organic solvent preferably is within the above ranges.
  • Alkyd resins comprising an unsaturated or saturated oil are classified by the amount of oil based on the total weight of the resin.
  • the amount of unsaturated or saturated oil is higher than 60 wt.-% (long-oil alkyd resin), between 40 wt.-% and 60 wt.-% (medium-oil alkyd resin), or lower than 40 wt.-% (short-oil alkyd resin) based on the total weight of the alkyd resin.
  • the alkyd resin is a medium-oil alkyd resin or a long-oil alkyd resin.
  • the alkyd resin is a drying or a non-drying alkyd resin.
  • Drying alkyd resins cure at approximately 20°C or by drying at 60°-80°C. Non-drying alkyd resins do not dry at these temperatures, but are cured by baking.
  • the composition further comprises a siccative (oil-drying agent), which catalyzes the curing of the alkyd resins.
  • siccatives are typically derived from cobalt, calcium, strontium, barium, manganese and iron ions.
  • the alkyd resin does not contain any siccatives.

  • additional as used herein has the meaning of “simultaneously” and/or “sequentially”.
  • biofilm refers to an assembly of microorganisms wherein cells stick to each other on the surface of a substrate.
  • growth of biofilm or “biofilm growth”, as used herein, refers to the microorganism built-up adhering to a surface.
  • reduction of the growth of a biofilm refers to the decrease, preferably the inhibition, of the microorganism built-up on a long term scale, i.e. at least 1 week, preferably at least 1 month, more preferably at least 1 year, even more preferably at least 3 years, on the surface being treated with a composition as described herein compared to the surface not being treated with a composition as described herein.
  • compositions as described herein are particularly suitable for simultaneously imparting antimicrobial properties to a surface and reducing, particularly inhibiting, the growth of a biofilm on the surface, thereby reducing, preferably inhibiting, the growth of biofilm on a surface and maintaining the microbial efficacy of the alkyd resins on a long term time scale (at least 2 weeks, preferably at least 1 month, more preferably at least 1 year, even more preferably at least 3 years).
  • the composition is free of any additional antimicrobial compound (except the organic solvent), in particular free of any biocidal product as defined in Article 3(1)(a) of the Regulation (EU) No. 528-2012 of the European Parliament and the Counsel of 22 May 2012.
  • the composition used in the present invention preferably does not contain any nanoparticles, such as metal nanoparticles, in particular silver nanoparticles.
  • the composition is free of silver, organotin and gum rosin.

  • composition of the present invention may comprise any further suitable compositions, in particular further organic solvents and also water.
  • the water content should, however, be at a concentration at which the formation of the equilibrium in the thickness of the alkyd resin is not adversely affected. In this regard, it was found that a water concentration of up to 50 % by weight, preferably up to 45 % by weight and more preferably up to 40 % by weight based on the total weight of the composition is generally tolerable.
  • the present invention furthermore relates to a method for the repeated sanitizing or cleansing of a surface comprising the repeated applying of a composition to the surface, wherein the composition comprises an alkyd resin and an organic solvent, wherein the alkyd resin comprises fatty acid residues, which contain at least 6 carbon atoms in their saturated or unsaturated aliphatic chain, and the organic solvent is selected from the group consisting of methanol, ethanol, n-propanol, iso-propanol, n-butanol, iso-butanol, tert-butanol, ethyl methyl ketone, acetone, ethyl acetate, and mixtures thereof.

  • Example 1 One composition according to the invention (example 1) and two comparative compositions (comparative examples 1 and 2) were prepared and repeatedly applied to the surface of an aluminum plate (10 cm x 10 cm). Each time 2 g of the composition were applied to the surface and spread with a soft cloth. The plate was weighed before the first application of the composition and after each application of the composition after the coating had been dried. From the weight gain it can be concluded whether the alkyd resin layer formed on the surface of the aluminum plate increases in thickness after each application of the composition.
