Definitions

  • the present invention concerns the use of a cleaning formulation comprising an additive, and a process for cleaning bottles, in particular returnable PET bottles, using such.
  • an alternative chelating agent is sodium gluconate. This has the advantages of being readily biodegradable and not increasing the foaming tendency of cleaning solutions. However, it is a weaker chela-ting agent and does not remove mould pads as effectively as EDTA, especially at relatively low caustic levels as required for low chemical damage when washing plastic bottles.
  • An object of the present invention is to yield an effective detergent additive not having the environmental drawbacks ensuing from the use of EDTA.
  • EP-A-325909 describes alkaline bottle cleaning compositions comprising end blocked ethoxylated nonionic surfactants. Builder and complexing agents may be present.
  • an alkaline washing formulation including an additive for a bottle washing formulation according to claim 1 and dependent claims 2-12.
  • This additive which is free of EDTA or similar chelating agents, is used with an alkaline washing formulation, most preferably a caustic soda based washing formulation, at a concentration of between 0.25 and 3%, preferably 1-2%, whereby in the case of PET bottles the concentration most preferably does not exceed 1.5% in order to minimize stress cracking.
  • This formulation is effective at achieving detergency, particularly against mould pads.
  • Sodium gluconate offers the advantages of being commercially available and readily soluble in both alkaline and acidic solutions, thus making the development of concentrated additives possible. Furthermore sodium gluconate will chelate both divalent and trivalent ions. As a result, in addition to facilitating the removal of mould pads, it will remove rust stains from the tops of crown capped bottles and prevent sodium aluminate precipitates forming when washing bottles which carry aluminium foil labels. Another consequence of its trivalent ion chelation capability is that clays extracted from old labels in the wash bath will be dispersed and not precipitate on the bottles being washed.
  • a wetting agent is an agent for reducing surface tension in order to increase the intimacy between the cleaning formulation and the soil.
  • the wetting agent has the following general formula: R 1 - (OC 2 H 4 ) n - (OC 3 H 8 ) m - OR 2 , wherein
  • Polyacrylates offer the advantages of being substantially inert, whereby environmental problems associated herewith are limited, being easily precipitated out of waste water, for example, with sewage. Due to their ready solubility they can be used at very concentrated levels, thereby increasing the effectiveness of the detergent additive.
  • the additive according to the present invention was primarily developed for use in cleaning formulations in soft water areas.
  • a scale forming preventing agent such as Dequest 2000TM or Bayhibit AMTM, is preferably added.
  • the additive can be formulated to be alkaline, acidic or pH-neutral, in the latter case preferably including a preservative, for example formaldehyde, to prevent micro-organisms feeding off the additive and causing this to deteriorate.
  • a preservative for example formaldehyde
  • This cleaning process is carried out below a maximum temperature of 60°C, above which thermal damage to PET bottles is possible, and between 50°C and 80°C for glass bottles.
  • test solutions consisted of solution b) plus 500 mg/l of the test additive.
  • No. Test Solution Total cleaning time for 3 bottles (min) 1 a) 1% caustic soda >22 2 b) 1% caustic soda + 0.5% base adjunct 14 3 c) 1% caustic soda + 0.3% SU 860 10 4 b) + SokalanTM PA 50 (Polyacrylate, M.W. 30,000 ex BASF) 12 5 b) + SokalanTM PA 25 PN (Polyacrylate, M.W. 4000 ex BASF) 11 6 b) + Versicol E7 (Polyacrylate, M.W. 26,000 ex Allied Colloids) 9 7 b) + NorasolTM LMW 45 (Polyacrylate, M.W. 4500 ex Norso-Haars) 9 8 b) + extra nonionic (180 mg/l) 8 Numbers 4-7 fall within the claimed range.
  • formulation 9 was developed for cleaning PET bottles, it would be equally suitable for cleaning glass bottles. In this case, it would not be subject to the temperature and caustic level limitations imposed on PET bottle washing.
