Definitions

  • the present invention relates to the use of an O / W emulsion, in particular a PIT emulsion, for the lubrication of conveyor belt systems in food processing plants and a lubricant concentrate based on wax esters.
  • the containers to be filled in the bottling plants are transported by transporters of various designs and materials, for example via plate conveyor belts or chain-like arrangements, which will generally be referred to below as transport chains.
  • the transporters make the connection between the different optional treatment stages of the filling process such.
  • the containers may be various forms, in particular glass and plastic bottles, cans, jars, barrels, beverage containers (CEC), paper and cardboard containers.
  • CEC beverage containers
  • the transport chains In order to ensure trouble-free operation, the transport chains must be lubricated in a suitable manner, so that excessive friction with the containers is avoided.
  • dilute aqueous solutions containing suitable friction-reducing agents are used for lubrication. With the aqueous solutions, the transport chains are brought into contact, for example by immersion or by spraying, which then speaks of immersion lubrication systems or automatic belt lubrication systems or central chain lubrication systems.
  • the chain lubricants hitherto used as lubricants are usually based on fatty acids in the form of their water-soluble alkali or alkanolamine salts or on fatty amines, preferably in the form of their organic or inorganic salts.
  • Lubricants based on N-alkylated fatty amine derivatives which contain at least one secondary and / or tertiary amine.
  • the WO 94/03562 describes a lubricant concentrate based on fatty amines and optionally conventional diluents or auxiliaries or additives, characterized in that it contains at least one polyamine derivative of a fatty amine and / or a salt of such an amine, wherein the proportion of said polyamine derivatives of fatty amines in the overall formulation to 100 wt .-% is.
  • the registration DE 199 42 535.3 provides lubricants based on polyhydroxy compounds, which are hydrophilic due to their molecular structure and at the same time improve the lubricating performance over amines commonly used as lubricants.
  • polyhydroxy compounds which are selected from alkanediols or alkanetriols, very particularly preferably glycerol, or their polymers and their esters and ethers.
  • chain lubricants adhere very well to the chains, as is the case with the very well-wetting fluorosurfactants, for example, forms the transport chains a firmly adhering film that is not easy to remove by rinsing with water.
  • the subject of the present invention is the use of an O / W emulsion in concentrated form or after dilution with water for lubricating conveyor belts in food processing plants.
  • phase inversion oil-in-water emulsions, henceforth called O / W emulsions, prepared and stabilized with nonionic emulsifiers undergo phase inversion upon heating.
  • phase inversion it is to be understood that at higher temperatures the outer, aqueous phase becomes the inner phase.
  • This process is usually reversible, which means that the original emulsion type re-forms on cooling.
  • location of the phase inversion temperature depends on many factors, for example the type and the phase volume of the oil component, the hydrophilicity and the structure of the emulsifier or the composition of the emulsifier system, compare for example! K. Shinoda and H.
  • the German patent application DE-OS-38 19 193 describes a process for the preparation of low-viscosity O / W emulsions of polar oil components, which is based on the method of phase inversion temperature (PIT method).
  • phase inversion temperatures below 100 ° C. are achieved by the presence of further coemulsifiers in addition to nonionic emulsifiers.
  • O / W emulsions based on polar oil bodies and non-ionic emulsifiers are then particularly finely divided and long-term stable when a mixture of polar oil, nonionic emulsifier and a special interface moderator to a temperature within or above the phase inversion temperature range heated - or the emulsion prepares at this temperature - and then the emulsion is cooled to a temperature below the Phaseninversion-Tempertur Schemees and optionally further diluted with water.
  • This method has the advantage that particularly finely divided emulsions are obtained which have excellent storage stability. Compared to the hitherto known state of the art, for example the DE-OS-38 19 193 , In addition, the phase inversion temperature is lowered, which is particularly favorable in practice because of the associated energy savings.
  • the oil-in-water emulsions prepared by the PIT method find use, e.g. as a skin and body care product, as a cooling lubricant or as a textile and fiber auxiliary. They are particularly preferred in processes for the preparation of emulsion-like preparations for skin and hair treatment.
  • German patent DE 197 03 087 C2 from which the use of appropriate PIT emulsions for the production of cosmetic refatting agents is known.
  • the O / W emulsion contains at least one wax ester.
  • Wax esters are esters of long-chain carboxylic acids with long-chain alcohols, which preferably follow the formula (1), R 1 CO-OR 2 (1) in which R 1 CO is a saturated and / or unsaturated acyl radical having 6 to 22, preferably 12 to 18 carbon atoms and R 2 is an alkyl and / or alkenyl radical having 6 to 22, preferably 12 to 18 carbon atoms.
  • Triglycerides are substances of the formula (2),
  • R 4 CO and R 5 CO independently represent linear or branched, saturated and / or unsaturated, optionally hydroxy- and / or epoxy-substituted acyl radicals having 6 to 22, preferably 12 to 18 carbon atoms and the sum (m + n + p) is 0 or numbers from 1 to 100, preferably 20 to 80.
  • the triglycerides may be of natural origin or synthetically produced.
  • hydroxy- and / or epoxy-functionalized substances such as, for example, castor oil or hydrogenated castor oil, epoxidized castor oil, ring opening products of epoxidized castor oils of different epoxide numbers with water and addition products of on average from 1 to 100, preferably from 20 to 80 and in particular from 40 to 60 mol these triglycerides.
  • Partial glycerides are monoglycerides, diglycerides and their technical mixtures, which may still contain small amounts of triglycerides due to their production.
  • the partial glycerides preferably follow the formula (3), in the R 6 CO for a linear or branched, saturated and / or unsaturated acyl radical having 6 to 22, preferably 12 to 18 carbon atoms, R 7 and R 8 are independently R 6 CO or OH and the sum (m + n + p ) is 0 or numbers from 1 to 100, preferably 5 to 25, with the proviso that at least one of the two radicals R 7 and R 8 is OH.
  • Typical examples are mono- and / or diglycerides based on caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, Petroselinic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidic acid, gadoleic acid, behenic acid and erucic acid and their technical mixtures.

  • the surfactants may have both a conventional broad and a narrow homolog distribution. Particularly preferred are addition products of on average 10 or 20 moles of ethylene oxide to cetearyl alcohol, stearyl alcohol and / or behenyl alcohol.
  • the addition products of ethylene oxide and / or of propylene oxide to fatty alcohols, fatty acids, alkylphenols, glycerol mono- and diesters and sorbitan mono- and diesters of fatty acids or to castor oil are known, commercially available products. These are homolog mixtures, whose average degree of alkoxylation corresponds to the ratio of the molar amounts of ethylene oxide and / or propylene oxide and substrate with which the addition reaction is carried out.
