Definitions

  • the present invention is directed to a cleaning composition for metallic surfaces. More particularly, the present invention is directed to cleaning compositions which can be formulated to have a low level of volatile organic compounds (VOC) and which are effective at removing adhesive materials from metallic surfaces.
  • VOC volatile organic compounds
  • automotive and other vehicular bodies and / or manufactured metallic parts can acquire unwanted materials on their surfaces including but not limited to adhesives, tar, grease and oils.
  • the build-up of such materials can be deleterious, particularly to moving parts, and it is therefore desirable to regularly remove such unwanted materials from the bodies and parts.
  • conventional cleaning methods are often inadequate for removing adhesives and in particular resin adhesives from metallic surfaces, a number of specialist cleaning compositions have been developed in the art.
  • WO 1995/005446 A1 (Dottolo Research Corporation) describes an auto body cleaner and all purpose adhesive remover composition which consists essentially of: (A) d-limonene; and, (B) from 2 to 12 percent by weight of a (nonionic and anionic) surfactant that is cocamide DEA/Dihexyl sodium sulfosuccinate (CDDSS).
  • a (nonionic and anionic) surfactant that is cocamide DEA/Dihexyl sodium sulfosuccinate (CDDSS).
  • a cleaning composition should be effective and safe to use.
  • a cleaning composition should also be relatively free from objectionable odor and have a low level of volatile organic compounds (VOC) therein, especially given that National and State Governments are rightfully enacting legislation to control the level of volatile organic compounds (VOC) in commercial products.
  • VOC volatile organic compounds
  • US Patent No. 6,017,863 (Cala et al. ) describes an aqueous cleaning solution for removing uncured adhesive resins from substrates.
  • the cleaning solution contains a surfactant mixture of N-alkyl-2-pyrrolidone and an aminocarboxylic acid surfactant. It has been found, however, that such solutions containing only surfactants and water are ineffective for removing many wholly or partially cured adhesives, and especially resin-based adhesives.
  • US Patent No. 6,399,554 A (Harrington et al. ) describes a cleaning composition for removing an adhesive from a hard substrate comprising: from 25 to 98 percent by weight of water; from 5 to 74 percent by weight of a chaotropic agent such as urea or guanadine hydrochloride; and, from 0.001 to 10 percent by weight of at least one surfactant.
  • WO 2012/000848 A2 discloses a cleaning composition for metallic surfaces of vehicles.
  • the composition comprises at least 90 wt.-% of methylene glycol dibutyl ether.
  • a cleaning composition for metallic surfaces of vehicles as defined in the appended claims, said composition comprising, based on the weight of the composition:
  • the composition provides an effective cleaning performance without emanating an unpleasant odor. Moreover, upon application to a surface, the composition creates a wet film which can endure on the surface for several hours if left untreated: this film serves to impart to the surface a temporary protection against corrosion.
  • a wipe comprising a substrate which is impregnated with a cleaning composition as defined hereinabove and in the appended claims.
  • kit of parts comprising: a cleaning composition as defined hereinabove and in the appended claims; and, a means for applying said composition to a metallic surface.
  • room temperature is 23°C plus or minus 2°C.
  • volatile organic compound is defined as a carbon-containing compound - excluding methane, carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, ammonium carbonate, and other exempt compounds under 40 Code of Federal Regulations (CFR) ⁇ 51.100(s) - that has a vapor pressure of at least 0.01 kPa at standard room temperature (EC Directive 1999/13/EC).
  • Measurement of the VOC emissions of the compositions of the present invention should be conducted in accordance with ASTM Standard Test Method D2369-90.
  • the measurement conditions of this standard should be directed to quantitatively measure the full content of VOC, wherein VOC is as defined above in this patent description.
  • solvent refers to any liquid that completely or partially dissolves a solid, liquid, or gaseous solute.
  • alkyl refers to monovalent group that is a radical of an alkane and which includes straight chain moieties, and where the number of carbon atoms suffices, branched moieties.
  • the alkyl group may optionally be substituted.
  • the term “substantially free” refers to a composition containing less than 0.5% by weight of the indicated component in the total composition.
  • anhydrous as used herein to define a composition means said composition contains less than 0.5% water, based on the total weight of the composition.
  • additive may refer to a compound or substance that may be added to another substance or composition for its ability to alter the properties of the other substance or composition.
  • vehicle means any form of self-propelled conveyance. Whilst the present invention has particular applicability to the metallic surfaces of automobiles, its use is not limited to automobiles: it may for instance find utility in the cleaning of farming equipment, earth-moving equipment, watercraft, carts and motorcycles, during the manufacture or repair of those vehicles.
  • metal means any type of metal, metal alloy, or mixture thereof, and specifically includes but is not limited to steel, iron, and stainless steel.
  • Component A) of the present cleaning composition consists of 2-(2-butoxyethoxy)ethanol.
  • Component B) of the present composition consists of 3-(2-ethylhexoxymethoxymethyl)heptane.
  • Compound of general Formula (II) is conventionally obtained by reacting aldehyde or ketone, respectively, and alcohol in the molar ratios of from 1:1 to 1:5: typically the reactants are dissolved in suitable solvents - such as toluene - and reacted at temperatures in the range of from 85 to 130°C.
  • suitable solvents - such as toluene - and reacted at temperatures in the range of from 85 to 130°C.
  • suitable solvents - such as toluene -
  • Component C) of the present composition consists of 2-[bis(2-hydroxyethyl)amino]ethanol.
  • the cleaning composition comprises, based on the weight of the composition:
  • the cleaning compositions of the present invention are preferably anhydrous. However, the dilution of the cleaning compositions with up to 5 wt.% of water, based on the total weight of the composition, is not precluded. When water is included, it should preferably be of at least potable grade and more preferably be deionized or distilled.
  • the cleaning composition may optionally comprise in toto up to 5 wt.%, based on the total weight of the composition, of additives.
  • Any additive(s) included should not have a deleterious effect on the performance of the composition and may, for instance, be selected from: stabilizers; emulsifiers; thickeners; biocides, in particular fungicides and / or bactericides; UV stabilizers; heat stabilizers; adhesion promoters, in particular silanes and/or titanates; pigments; and, fluorescent indicators or dyes.
  • dyes and fluorescent indicators it is possible to determine visibly - and respectively under ambient light or with the assistance of a UV light - whether a substrate has or has not been treated with the cleaning composition.
  • the use of fluorescent indicators can be especially advantageous when the substrate surfaces in question are visible: it is possible for the treatment to be detected but to be invisible to a viewer under normal daylight, so that the aesthetic aspect of the surface is not negatively impaired.
  • the cleaning composition of the present invention may only contain minor amounts of volatile organic compounds (VOC). More specifically, it is preferred that the VOC content of the cleaning composition is less than 1 wt.%, based on the total weight of the composition, or even more preferably the cleaning composition of this invention is substantially free of VOC.
  • VOC volatile organic compounds
  • the cleaning compositions of the present invention may be prepared by mixing of the components under sufficient shear forces to yield a homogeneous mixture. It is considered that this can be achieved without special conditions or special equipment. That said, suitable mixing devices might include: static mixing devices; magnetic stir bar apparatuses; wire whisk devices; augers; batch mixers; planetary mixers; C.W. Brabender or Banburry® style mixers; and, high shear mixers, such as blade-style blenders and rotary impellers.
  • the surfaces can be those which are disposed on the interior or exterior of the vehicle or which will be so disposed upon assembly or repair of a given part of a vehicle.
  • the pre-treatment of such surfaces to remove loose dirt and particulate materials prior to the application of the cleaning composition is not precluded in the present invention and can indeed be beneficial in some circumstances.
  • the cleaning composition of the present invention is an eye and skin irritant and therefore its use necessitates appropriate protective apparel. That said however, the cleaning composition may still be applied to the metallic surface by conventional application methods such as wiping with an impregnated material, flooding, dipping, brushing, roll coating, doctor-blade application, air-atomized spray, air-assisted spray, airless spray, high volume low pressure spray, air-assisted airless spray and high-speed rotation bell. Whilst such application methods can be performed at quite elevated temperatures, it is here preferred that the cleaning compositions be applied at a temperature of less than 40°C, for example at less than 30°C or at room temperature.
  • the viscosity of the cleaning composition will generally be from 0.005 to 1 Pa.s (50 cps to 1000 cps), as measured using a Brookfield viscometer at 25°C but, as would be recognized by a skilled practitioner, the viscosities which are appropriate for the different application methods can vary considerably.
  • the cleaning composition should generally be applied to the surface(s) to be cleaned in an amount of from 5 to 200 g/m 2 , preferably from 10 to 100 g/m 2 , for example from 10 to 50 g/m 2 .
  • the cleaning composition may be immediately removed or be allowed to sit upon the substrate surface - and, if applicable, penetrate the contaminants disposed on the surface - before being removed therefrom using, for example, a wipe composed of a suitable substrate.
  • This rest or penetration time can be beneficial as a wet film of the cleaning composition formed on the surface can provide temporary corrosion protection for that surface.
  • the appropriate rest or penetration time will depend on the amount of cleaning composition applied and the condition and morphology of the surface to be cleaned. Generally a rest or penetration time of up to 20 minutes - for example of from 0 to 15, or from 0.5 to 10 minutes - should be allowed under standard conditions (20°C, 65% Relative Humidity). However, it is noteworthy that good cleaning results have been obtained after 4 hours and even up to 24 hours after the application of the cleaning composition.
  • the treatment of the surface with the cleaning composition should serve to remove any contaminants from the surface. It may be necessary to remove the cleaning composition using means which allow for the application of pressure to the surface contaminants, thereby facilitating their removal. For example, manual pressure may be applied to a wipe or rag to lift or scrape away impurities, oils and uncured adhesives from a surface, either simultaneously with or subsequent to the application of the cleaning composition to the surface.
  • the cleaning composition is applied to a surface using a first wipe which is impregnated with a first amount of the cleaning composition.
  • further cleaning composition is applied using second and, if desired, further wipes which may be impregnated with, respectively, second, third, fourth etc. amounts of the cleaning composition.
  • the second and further amounts may be the same or different from the first amount: they may moreover be the same or different from eachother. It is however preferred that the second and, if applicable, further amounts of the cleaning composition are each less than said first amount to ensure that a diminished amount of the cleaning composition remains on the surface after the first wiping step.
  • Residual cleaning composition remaining on the surface after its treatment can form visible streaks, residues and / or Newton's rings on that surface.
  • Such residual composition can however be fully removed from the surface through further processing.
  • the composition can be removed in degreasing baths found, for instance, in vehicle paint shops. Special mention in this regard might be made of alkaline degreasing baths which are set at an elevated temperature of from 30° to 60°C and which further comprise surfactants.
  • a formulated wipe which is impregnated with the above described cleaning composition.
  • the substrate used to make the formulated wipes is any substrate that can be impregnated with a cleaning composition - at least on its surface - to provide a suitable cleaning article for the surface concerned.
  • the substrate for the wipe is generally an absorbent or adsorbent material that is insoluble in the cleaning composition and which is not corrupted by that composition: a preference for wipes comprising or consisting of non-woven sheets might be mentioned.
  • Non-woven sheets typically contain at least one layer that is made of: natural fibers; one or more synthetic fibers; or, blends of natural fibers and said one or more synthetic fibers.
  • suitable synthetic fibers include: polyester fibers, such as polyethylene terephthalate fibers; rayon; viscose; nylon; polypropylene fibers; and, polyethylene fibers.
  • Exemplary natural fibers include: wood pulp; cellulose polymers; and, starch.
  • the constituent fibers of the sheet may be melt blown, co-formed, air laid, spun bond, wet laid, bonded, dash-carded, hydro-entangled or otherwise formed into a sheet by a combination of said methods.
  • a binder may or may not be present in the sheet.
  • Non-woven sheets may be characterized by an areal weight that is dependent on the density of the fibers making up the sheet and the relative number of fibers per unit area. Without intention to the limit the present invention, suitable non-woven sheets will typically have an areal weight from 5 to 200 g/m 2 , for example from 5 to 100 g/m 2 , from 20 to 80 g/m 2 or from 30 to 70 g/m 2 .
  • Such substrates might include: woven materials, such as those made from cotton fibers, from fibers of synthetic polymers, or from blends of cotton and synthetic fibers; and, foam materials, such as regenerated cellulose or polyurethane foams.
  • the wipes can be individually sealed with a heat-sealable or glue-able thermoplastic overwrap.
  • the wipes might be packaged as numerous individual sheets which are then impregnated or contacted with the liquid cleaning ingredients for economical dispensing: such individual wipes may be nested or interleaved within the package such that the removal of one individual wipe advances the next wipe and so forth.
  • the wipes might be formed as a continuous web during the manufacturing process and loaded into a suitable dispenser equipped with a closure - preferably a re-sealable closure - which functions to isolate the moistened wipes from the external environment.
  • Such a dispenser may viably be provided with a means of sizing the desired length of the wipe form the continuous web, such as a knife blade or serrated edge.
  • a means of sizing the desired length of the wipe form the continuous web such as a knife blade or serrated edge.
  • the continuous web of wipes can be scored, perforated, folded, segmented, or partially cut into uniform or nonuniform sizes or lengths.
  • the size and shape of the wipes should have dimensions suitable for use by a single person.
  • the wipes should be small enough to be stored and transported easily, yet large enough to provide adequate cleaning of surface concerned.
  • the wipes are manufactured by applying the cleaning composition to a substrate by, for example, dipping, immersion or spraying.
  • the amount of cleaning composition which is applied to the wipe can be varied to provide a desired loading of the components thereof and such variation might be effected by metering the composition during a spraying operation or by moving the substrate past an application source at a controlled rate. If necessary, excess composition can be removed from the wipe after application by shaking, rolling, drip drying and the like.
  • a further aspect of the present invention is constituted by a kit of parts which comprises the above described cleaning composition and a means for applying said composition.
  • a suitable kit might comprise: a plurality of the formulated wipes as described hereinabove which are impregnated with the cleaning composition and disposed in a dispenser or packaging; and, instructions for the use of those wipes in written form, cartoon form, pictorial form or combinations thereof.
  • a suitable kit may comprise: a container of the cleaning composition; a plurality of absorbent or adsorbent wipes; and, instructions for both the impregnation of those wipes with the cleaning composition and the subsequent use of the wipes. Kits may of course be provided with other items, including but not limited to: means to remove excess composition from the surface to be cleaned; and, protective clothing, masks and eye wear.
