Definitions

  • the present invention relates to the use of an O / W emulsion containing a wax ester, in concentrated form or after dilution with water for lubricating conveyor belts in food processing plants.
  • 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 printer 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 are available, on the one hand have good adhesion to the chains, have good lubricating properties and form a film that can be easily removed when needed again from the chains.
  • chain lubricants should be in storage stable formulation.
  • 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 phase volume of the oil component, the hydrophilicity and the structure of the emulsifier or the composition of the emulsifier system.
  • 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 nonionic emulsifiers are then particularly fine-particle and long-term stable, if 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 is prepared 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 , Beyond that lowered the phase inversion temperature, 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.
  • thermoformed thermoplastic articles comprising a thermoplastic and a liquid hydrocarbon oil composition.
  • the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymer structure of the claimed container to prevent or inhibit stress cracking in such materials.
  • EP 0345586 A1 describes a process for preparing low viscosity oil-in-water emulsions from oil components comprising 50-100% by weight of mono- and / or diesters of at least 10 carbon atoms and possibly 0-50% by weight of fatty acid triglycerides and / or 0-25% by weight of fatty acid triglycerides
  • DE 41 40 562 A1 describes a process for the preparation of finely dispersed long-term stable oil-in-water emulsions based on oil mixtures with a high proportion of polar oil components by emulsification in the presence of 8 to 85 wt .-% water.
  • the invention relates to the use of an O / W emulsion containing a wax ester, in concentrated form or after dilution with water for lubricating conveyor belts in food processing plants.
  • 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), in the R 3 CO, 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.

  • 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),
  • R 7 and R 8 are independently R 6 CO or OH and the sum (m + n + p ) for 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.
