WO 97/19157 PCT/EP96/04992 1 CLEANING FORMULATION, ADDITIVE FOR A CLEANING FORMULATION AND PROCESS FOR CLEANING BOTTLES USING SUCH The present invention concerns an additive for a cleaning formulation, a cleaning formulation comprising this additive, and a process for cleaning bottles, in particular returnable PET bottles, using such.
Large quantities of beverages including carbonated soft drinks such as Cola's are sold in returnable bottles made of either glass or plastic, particularly PET (PolyEthylene Tetraphthalate). These bottles must be thoroughly cleaned and disinfected before being refilled to ensure product quality is not adversely affected.
One of the main problems with beverage bottles after they have been emptied is that moulds can grow in residual product and produce characteristic mould pads.
These are difficult to remove by the main component used in bottle washing detergents (caustic soda) unless additional components, namely chelating agents are also present. The preferred chelating agent from the point of view of mould pad removal is EDTA. However, there is considerable pressure from environmental groups and some governments to reduce or preferably eliminate the use of EDTA. An additional drawback of EDTA is that it makes bottle washing solutions more prone to foam. This can adversely affect the performance of the cleaning process unless an antifoam is added.
Not only is such an addition costly, it increases the pollution capability of the detergent solution and where plastic bottles are concerned, it- can increase chemical damage of the bottles due to stress cracking.
Instead of EDTA, 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- WO 97/19157 PCT/EP96/04992 2 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.
According to a first aspect of the invention, there is provided an additive for a bottle washing formulation according to claim i.
This additive, which is free of EDTA or similar chelating agents, is preferably used with an alkaline washing formulation, most preferably a caustic soda based washing formulation, at a concentration of between 0.25 and preferably 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. According to the present invention the wetting agent has the following general formula: WO 97/19157 PCT/EP96/04992 3 R, (OC2H 4
(OC
3 Ha), OR, wherein R, alkyl chain of length between Cg and C 20 (preferably CI 0 to Cs) R2 H, alkyl (CI to Cs) or benzyl n 1-20 (preferably 2 to m 0 15 (preferably below 5 for biogradability) and is preferably present as a component of a non-ionic blend, which is a blend further comprising an antifoaming agent and a rinsing agent, in order to optimize cleaning.
A preferred wetting agent is Plurafac LF 131.
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.
Further preferred features of the additive according to the present invention are found in the accompanying claims.
The additive according to the present invention was primarily developed for use in cleaning formulations in soft water areas. When desired for use in hard water areas, a scale forming preventing agent, a phosphonate such as Dequest 2 000 TM 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.
According to a second aspect of the present invention there is provided a bottle washing formulation comprising the above mentioned additive.
WO 97/19157 PCT/EP96/04992 4 According to a third aspect of the present invention there is provided a process for cleaning bottles, in particular returnable PET beverage bottles.
This cleaning process is preferably carried out below a maximum temperature of 60 0 C, above which thermal damage to PET bottles is possible, and between 50 0 C and 0 C for glass bottles.
The invention will now be described by way of the following examples.
A number of new PET bottles were soiled with tomato juice which had been inoculated with the mould Aspergillus niger. The soil was allowed to remain in the bottles for 6 weeks after which the moulds had grown into visible colonies which were strongly attached to the PET surface. Cleaning tests were carried out in laboratory scale bottle washer at 60 0 C which is the maximum safe temperature for washing PET bottles. The detergent solutions were sprayed as a pencil jet onto the inside base of an upturned bottle at a flow rate of 4 1/min. The time for all visible soil to be removed was noted. For each detergent, 3 bottles were cleaned. The table below gives the total time for the 3 bottles to be cleaned.
Three reference solutions are included: a) 1% caustic soda b) 1% caustic soda plus 0.5% base adjunct sodium gluconate 1.2% nonionic blend) c) 1% caustic soda plus 0.3% SU 860, wherein SU 860 is a commercially produced adjunct based on EDTA (between 30% and 35% as EDTA Na 4 and additionally comprising sodium gluconate and nonionic wetting and antifoaming agents The remaining test solutions consisted of solution b) plus 500 mg/l of the test additive.
WO 97/19157 PCT/EP96/04992
TABLE
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 4 b) Sokalan PA 50 (Polyacrylate, M.W. 30,000 ex BASF) 12 b) Sokalan 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) Norasol LMW 45 (Polyacrylate, M.W. 4500 ex Norso-Haars) 9 8 b) extra nonionic (180 mg/1) 8 The tests were carried out at caustic soda levels of less than which is the limit for safe washing of PET bottles. Stress cracking tests showed that the effect of the product on stressed PET was less than that of the currently recommended EDTA based product.
On the basis of the above results, a formulation 9 was developed which consisted of Material Sodium gluconate 20.0 Norasol LMW 45 11.0 Sodium Cumene Sulphonate 15.0 Nonionic blend 4.8 Sodium hydroxide water to 100.0 WO 97/19157 PCT/EP96/04992 6 Cleaning tests showed that 1% caustic soda 0.2% formulation 9 cleaned 3 bottles which had been aged for 12 weeks in an aggregate time of 10 minutes while 1% caustic soda 0.3% SU 860 required 12 minutes and 1% caustic soda 0.3% of a known gluconate based adjunct (Stabilon Flssig ex Henkel) required 16 minutes.
Although 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.
