    AWAPATENT AB Kontor/HandläggareMalmö/Mikael Bergstrand Anolytech AB Ansökningsnr Vår referens SE-21049527 NEW COMPOSITION AND USE Field of invention The present invention relates to the field of agriculture and breeding ofdomestic animals, in particular milking domestic animals such as cows andsheep. More specifically, the invention provides a composition comprising ananolyte fraction and a specific tenside preparation. The invention alsoprovides a method of using the composition as well as the tenside preparationfor washing domestic animals as well as a washing method suitable for saidanimals.
    Technical background Electrolysis processes of aqueous alkali chloride solutions for producingchlorine, hydrogen and alkali metal hydroxides are well-known in the art. Onesuch process is disclosed in US 4,108,742, wherein the electrolysis is carriedout in a cell that has been divided into cathode and anode chambers by acation exchange membrane. As one objective of the technology of US4,108,742 is to produce chlorine gas, the electrolysis reaction is run at a lowpH.
    Electrochemical activation or electro-activation of dilute salt solutions in waterhas been the subject matter of several prior patents and publications. Theprior art commonly discloses the use of electrochemical activation to producean anolyte solution and a catholyte solution. Those who are engaged in theart will appreciate that an anolyte solution has a positive oxidation-reductionpotential (ORP) or redox potential, which is oxidizing and has microbiocidalproperties. The catholyte solution, on the other hand, has a negative ORP,has dispersive and surface active properties and can be used as a reducingagent.
    Salts used in the prior art almost exclusively refer to sodium chloride (NaCl)and in most prior art applications chloride-based salts are used in a dilutedform. However, there are various applications in which anolyte or catholyteare used in an undi|uted form, but in many of these applications a majordisadvantage of chloride-based or chloride-derived activated solutions is thatthey are corrosive to the materials with which they come into contact. This isparticularly intolerable in medical applications where the solutions typicallycould be used for cold sterilization of medical instruments.
    One such sterilization technology is disclosed in GB, A, 1,428,920. Accordingto this document, a bacteria-laden surface is disinfected by applying asolution of hypochloric acid (HCIO) generated by electrolyzing an aqueoussolution of NaCl at a pH within the range of 6 - 7. Another similar disinfectionmethod is described in WO99/20129. An animal product is exposed to anelectrochemically activated, anion-containing aqueous solution. As aconsequence, potentially harmful and/or destroying microorganisms are killedand the shelf life of the animal product is prolonged. lt should be kept in mind that objective of the technology disclosed in GB1,428,920 as well as WO99/20129 is sterilization and thus to kill allmicroorganisms around. When carrying out such processes, presence ofchlorine gas is not considered to be a serious drawback and substantialamounts of chlorine are indeed released. lt has generally been considered tobe much more important to achieve a high degree of sterilization than toprotect the close environment from high doses of chlorine.
    When breeding domestic animals such as cows, it is important to considercontamination of potentially harmful microorganisms. Typically, theenvironment in cowsheds and barns is very rich in microorganisms.Accordingly, it is highly probable that domestic animals in such environmentshave such microorganisms on their body surface. lt is especially important toconsider such presence of microorganisms regarding milk-producing 3 domestic animals. Bacteria present on the surface of the udder of a milkingdomestic animal, such as a cow, a sheep, a buffalo or a goat, maycontaminate the milk produced by the animal. lt is therefore advantageous toremove such bacteria from the udder before commencing the milkingoperation. Furthermore, it is also advantageous to remove such bacteria aftermilking as the teat canal normally is open for a while after milking andbacteria potentially causing mastitis may enter the udder through the opencanal. However, the skin and fur of such animals and in particular their uddersoften have a high fat content which renders it difficult to wash away lipophilicmicroorganisms without using any detergents.
    There have been attempts to combine anolyte preparations and tensidepreparations in order to obtain a disinfecting composition that could be usedfor washing the body surface of domestic animals. One such attempt isdisclosed in GB 1,184,200, where water-soluble alkoxylated lanolin is addedto an aqueous solution of hypochloric acid. However, most detergentpreparations including alkoxylated lanolin destabilize the anolyte preparation.Accordingly, the disinfecting capability is also reduced. Therefore, it is statedin GB 1,184,200 that the composition should be used as quickly as possibleafter mixing. Furthermore, many detergent preparations are skin-irritating inthose concentrations that are needed in order to get sufficient effect.
    Accordingly, there is a need for a combination of an anolyte preparation and atenside preparation where the tenside preparation does not destabilize theanolyte and where the resulting combination is not skin-irritating.
    Summary of the inventionThe objective problem is solved by the present invention by providing a composition for washing domestic animals, and in particular udders of domestic milking animals such as cows and sheep, comprising: 4 a) an anolyte fraction obtained by electrolysis of a sodium chloride solution ata pH within the range of 6.0 - 7.0, said anolyte fraction having an oxidationreduction potential (ORP) within the range of 450 - 950 mV; and b) an aqueous tenside preparation containing 1 - 10 % (wt) chlorosulfonatedand saponified paraffin oils (Chemical Abstract Ref.

No. 68188-18-1), 0.1 - 0.5 % (wt) 2-phenoxyethanol, and 0.005 - 0.1 % (vvt) of at least one compound selectedfrom the group of methyl paraben, ethyl paraben, propyl paraben, butylparaben and isobutyl paraben as an additive to an anolyte preparation in amethod of washing domestic animals, and in particular a method of washingudders of domestic milking animals such as cows and sheep. ln a fourth embodiment, the present invention provides a method for washingdomestic animals, and in particular udders of domestic milking animals suchas cows and sheep, comprising the steps of mixing: a) an anolyte fraction obtained by electrolysis of a sodium chloride solution ata pH within the range of 6.0 - 7.0, said anolyte fraction having an oxidationreduction potential (ORP) within the range of 450 - 950 mV; and b) an aqueous tenside preparation containing 1 - 10 % (wt) chlorosulfonatedand saponified paraffin oils (Chemical Abstract Ref. No. 68188-18-1), 0.1 - 5 0.5 % (vvt) 2-phenoxyethanol, and 0.005 - 0.1 % (wt) of at least onecompound selected from the group of methyl paraben, ethyl paraben, propylparaben, butyl paraben and isobutyl paraben; in such a way that the anolyte fraction constitute 94 - 99 % (wt) and theaqueous tenside preparation constitute the balance up to 100 % (vvt) of theresulting composition; and washing the domestic animals, in particular the udders of milking domesticanimals such as cows and sheep with the resulting composition.
    Detailed description of the present invention The present invention is based on the discovery that a specific anolytepreparation and a specific tenside preparation could be combined in specificconcentrations without destabilizing the anolyte preparation and withoutcausing skin irritations for staff taking care of the animals or for the animalsthemselves.
    Accordingly, in a first embodiment, the invention provides a composition forwashing domestic animals, and in particular udders of domestic milkinganimals such as cows and sheep, comprising: a) an anolyte fraction obtained by electrolysis of a sodium chloride solution ata pH within the range of 6.0 - 7.0, said anolyte fraction having an oxidationreduction potential (ORP) within the range of 450 - 950 mV; and b) an aqueous tenside preparation containing 1 - 10 % (wt) chlorosulfonatedand saponified paraffin oils (Chemical Abstract Ref. No. 68188-18-1), 0.1 -0.5 % (vvt) 2-phenoxyethanol, and 0.005 - 0.1 % (wt) of at least onecompound selected from the group of methyl paraben, ethyl paraben, propylparaben, butyl paraben and isobutyl paraben; wherein the anolyte fraction constitute 94 - 99 % (wt) and the aqueoustenside preparation constitute the balance up to 100 % (vvt) of thecomposition. 6 Anolyte preparations having a pH value within the range of 6.0 - 7.0 do notcontain much dissolved chlorine gas (Free Available Chlorine, FAC). lnstead,the chlorine is present as bacteriocidal hypochloric acid. Hypochloric acid isnot stable at acid and alkaline pH values and it is essential to maintain a pHvalue within the claimed range in order to ensure high content. lt is preferredthat pH of the anolyte fraction is within the range of 6.2 - 6.8, and mostpreferred that it is within the range of 6.4 - 6.6. Because of the instability ofhypochloric acid, it is advantageous to produce anolyte preparations locallyand close to the site where the preparations are to be consumed. Therefore,when carrying out the present invention it is recommended to produce anolytepreparations at the farm site.
    Hypochloric acid is an oxidizing compound. Accordingly, an aqueous solutionof the compound is associated with an ORP larger than 0 mV. As mentionedabove the ORP of the anolyte is within the range of 450 - 950 mV, andpreferably within the range of 750 - 900 mV. Information regardingmeasurement of ORP and FAC can be found in Technical Bulletin No. 24,issued by Aquarius Technologies Pty. Ltd. (AU).(httpz//wwvvaaouariustech.com.aulpdfsitech~ bulletins/Undrstnd GX Bio ÛRPpdf) lt is preferred that the aqueous tenside preparation contains 2 - 8 % (wt)chlorosulfonated and saponified paraffin oils, 0.2 - 0.4 % (wt) 2 -phenoxyethanol, 0.05 - 0.075 % (wt) methyl paraben, 0.01-0.02 % (wt) ethylparaben, 0.005 - 0.01 % (wt) propyl paraben, 0.01 - 0.02 % (vvt) butylparaben, and 0.005 - 0.01 % (wt) isobutyl paraben. Tenside preparations inaccordance with the present invention could be obtained from Trikem AB(SE). lt is preferred that the anolyte fraction constitutes 95 - 98 % (vvt) and theaqueous tenside preparation constitutes the balance up to 100 % (vvt). 7 ln a second embodiment, the present invention provides a method-of-use of acomposition according to the first embodiment for washing domestic animals,in particular udders of milking animals such as cows and sheep. ln a third embodiment, the present invention provides a method-of-use of anaqueous tenside preparation containing 1 - 10 % (wt) chlorosulfonated andsaponified paraffin oils (Chemical Abstract Ref. No. 68188-18-1), 0.1 - 0.5 %(wt) 2-phenoxyethanol, and 0.005 - 0.1 % (wt) of at least one compoundselected from the group of methyl paraben, ethyl paraben, propyl paraben,butyl paraben and isobutyl paraben as an additive to an anolyte preparation ina method of washing domestic animals, and in particular a method of washingudders of domestic milking animals such as cows and sheep.
    Preferably, the aqueous tenside preparation contains 2 - 8 % (wt)chlorosulfonated and saponified paraffin oils, 0.2 - 0.4 % (wt) 2 -phenoxyethanol, 0.05 - 0.075 % (vvt) methyl paraben, 0.01-0.02 % (vvt) ethylparaben, 0.005 - 0.01 % (wt) propyl paraben, 0.01 - 0.02 % (wt) butylparaben, and 0.005 - 0.01 % (wt) isobutyl paraben. ln a fourth embodiment, the present invention provides a method for washingdomestic animals, and in particular udders of domestic milking animals suchas cows and sheep, comprising the steps of mixing: a) an anolyte fraction obtained by electrolysis of a sodium chloride solution ata pH within the range of 6.0 - 7.0, said anolyte fraction having an oxidationreduction potential (ORP) within the range of 450 - 950 mV; and b) an aqueous tenside preparation containing 1 - 10 % (wt) chlorosulfonatedand saponified paraffin oils (Chemical Abstract Ref. No. 68188-18-1), 0.1 -0.5 % (wt) 2-phenoxyethanol, and 0.005 - 0.1 % (wt) of at least onecompound selected from the group of methyl paraben, ethyl paraben, propylparaben, butyl paraben and isobutyl paraben; in such a way that the anolyte fraction constitute 94 - 99 % (wt) and theaqueous tenside preparation constitute the balance up to 100 % (wt) of theresulting composition; and 8 washing the domestic animals, in particular the udders of milking domesticanimals such as cows and sheep with the resulting composition. lt isadvantageous to wash said udders before and/or after milking. lt is, of course,also advantageous to wash other parts of the animal body with thecomposition according to the invention.
    The invention will now be further disclosed in the following examples withreference to the enclosed Fig. 1 which briefly outlines a process for producingan anolyte preparation.
    Example 1: Preparation of an anolvte fraction at a farm site The anolyte fraction produced at a farm site is typically based on localincoming water. The incoming water typically originates from a well but mayalso originate from a river, lake or another water source. A suitable setup forproducing anolyte is shown in Fig. 1. Accordingly, incoming water flow 1 at afarm site is conveyed through pH sensor 6. The pH value of the incomingwater is continuously monitored and, if necessary, adjusted to a value withinthe range of 6.0 - 7.0. The water flow is lead through humus/particle filter 2and a filter 4 absorbing ions, such as Ca2+, Fe2+, Fes* and IVln2+. Filter 4 istypically composed in response to a chemical analysis of the incoming water.The process water is then transported to a branch point 10, where a smallportion of the water flow is lead through magnet valve 12 to sodium chloridetank 14, wherein sodium chloride is added manually. The amount of saline insodium chloride tank 14 is monitored by level sensor means 16, whichcontrols magnet valve 12. When the saline level in tank 14 falls under apredetermined level, level sensor means 16 sends signals to magnet valve 12so that the valve 12 is opened. Saline is pumped off from sodium chloridetank 14 by dosage pump 20. The remaining portion of the water flow isforvvarded by pressure regulation means 18 to branch point 22, where it isreunited with saline from dosage pump 20. The united water flow is thenforwarded to electrochemical reactor 24, wherein it is split into anolytechamber 26 (containing an anode) and catholyte chamber 28 (containing a 9 cathode). The Chambers are separated by a ceramic membrane and anelectric current is lead through the chambers. The current is measured bycurrent measurement means 30 which in turn controls dosage pump 20. Ahigher current results in more saline transported by dosage pump 20. Theflow out from electrochemical reactor 24 is controlled by valve means 32(catholyte flow) and 34 (anolyte flow). The produced catholyte is collected intank 36 and not used further in the context of the present invention. Theproduced anolyte is collected in tank 38. A level sensor means 40 controlsvalve means 34. Before using the anolyte preparation in the presentinvention, the ORP of the preparation is measured with ORP sensor 52. lfORP of the preparation is within the claimed range of 450 - 950 mV,preferably 750 - 900 mV, the preparation could be used in the presentinvention. ln case the ORP is lower, the anolyte fraction is discarded and anew fraction is produced in accordance with the above described procedure.
    Example 2: Stabilitv of a mixture of an anolvte fraction and a tensidepreparation An anolyte fraction was produced in accordance with what is disclosed inExample 1. The pH value was measured to be 6.5 and it had an ORP of 832mV. 20 ml of an aqueous tenside preparation containing 4 - 8 % sodiumalkane sulfonate, 0.2 - 0.4 % 2-phenoxyethanol, 0.05 - 0.075 % (wt) methylparaben, 0.01-0.02 % (wt) ethyl paraben, 0.005 - 0.01 % (wt) propyl paraben,0.01 - 0.02 % (wt) butyl paraben, and 0.005 - 0.01 % (wt) isobutyl parabenwas added to 980 ml of the anolyte fraction. After 4 hours, the resultingmixture still had an ORP of 750 mV indicating presence of oxidizinghypochloric acid and hence bacteriocidal activity.
    Example 3: Treatment of cow's udders with an anolvte fraction containinq anaqueous tenside preparation A composition produced as in example 3 was used to treat cow's udders. Theudders of 23 cows, and in particular their teats were dipped in the composition once daily for three months. No Iesions were detected on any ofthe udders.
