Definitions

  • the present invention relates to a cleaning wipe which is designed in particular for the cleaning of hard surfaces such as are found in the household, or in institutional or hospital environments.
  • the wipe has a textured abrasive surface on one side and is impregnated with a hard surface cleaning formulation.
  • Liquid all purpose hard surface cleaning compositions have historically been generally comprised of two types.
  • the first type is a particulate aqueous suspension containing suspended water-insoluble abrasive particles.
  • cleaners of this type suffer a stability problem, since it is difficult to suspend the insoluble abrasive particles in the composition. Others have received poor acceptance by consumers because of their "gritty" feel. This may cause people to be reluctant to use them for fear of scratching the surface to be cleaned. In addition, they may leave abrasive insoluble particles behind on the treated surface that are difficult to remove and require rinsing or wiping as part of the cleaning process.
  • the second type is a liquid detergent without suspended abrasive, which is often preferred by consumers over the first type.
  • liquid detergents of this second type generally contain a high level of non-volatile active ingredients such as surfactant and/or detergent builder salts, in order to improve cleaning in the absence of added abrasive.
  • This high level of non-volatiles tends to leave films, spots or streaks on cleaned unrinsed surfaces, particularly shiny surfaces such as glass or stainless steel.
  • Such liquids require thorough rinsing of the cleaned surfaces which is time-consuming and inconvenient for the user.
  • the present invention provides an impregnated wipe suitable for the cleaning of hard surfaces, which wipe comprises an absorbent substrate having on one side a textured abrasive surface formed from nodules and/or striations of abrasive material applied thereon, the abrasive material having a hardness ranging from 40 to 100 Shore D units, and the substrate incorporating an aqueous hard surface cleaning composition comprising:
  • Wipes according to the invention show both excellent cleaning and superior "end-results" (i.e. no significant residues, streaks or spotting left behind after use). It has been found that these properties are apparent even at very low levels of active ingredient and, surprisingly, when the textured surface is of relatively low abrasivity. This is particularly advantageous in the context of delicate, easily-damaged surfaces in the household such as plastics.
  • Wipes of the invention are especially suitable for the cleaning of hard surfaces.
  • hard surfaces are meant those surfaces which are typically found in the household, or in institutional or hospital environments, and which are prone to contamination. Examples include lavatory fixtures, lavatory appliances (toilets, bidets, shower stalls, bathtubs and bathing appliances), wall and flooring surfaces and those surfaces associated with kitchen environments and other environments associated with food preparation.
  • peel it is meant a disposable substrate such as a sheet or cloth which has been pre-treated with the aqueous composition comprising ingredients (i) and (ii) as defined above (hereinafter referred to as “the composition of the invention”) so as to incorporate the composition of the invention into or onto the substrate prior to its use by the consumer.
  • This product form is particularly advantageous since it allows for safe and convenient one-step cleaning of surfaces by the user, without the need for dilution or spraying.
  • the wipe is formed by absorbing the composition of the invention onto the substrate to form a moist wipe.
  • a batch of wipes can then be placed in a container which can be opened when needed and when closed, sufficiently seals to prevent evaporation of any components from the composition.
  • the composition of the invention is impregnated at the desired weight into the substrate which may be formed from any woven or nonwoven fibre, fibre mixture or foam of sufficient wet strength and absorbency to hold an effective amount of the composition.
  • Wipes of the invention comprise an absorbent substrate having on one side a textured abrasive surface as described above.
  • Preferred materials used to form the wipe include in general all nonwoven materials with sufficient wet strength and liquid absorption capacity to contain the aqueous composition of the invention and to deliver it in use.
  • suitable nonwoven materials include fibres from natural sources such as viscose, cellulose, or from synthetic origin such as polypropylene or polyester. Especially suitable are mixtures of these materials such as viscose/polyester, viscose/polypropylene, and cellulose/polyester.
  • latex binders can be added.
  • These latex binders can typically include one or more monomers selected from styrene-2-ethyl hexyl acrylate, butyl acrylate, methyl methacrylate, ethyl acrylate, methyl acrylate, acrylonitrile and vinyl acetate.
  • the materials can be formed into webs using technologies generally known in the art such as carding, drylaid, wetlaid, airlaid and extrusion.
  • Webs can be bonded using technologies known in the art such as needlepunch, stitchbond, hydroentangling, chemical bonding, thermal bonding, spunbinding, spunlacing and meltblowing.
  • a preferred method is spunlacing.
  • the wipe may be a single layer structure or a multilayer structure formed from layers of materials of the above general type, which may be the same or different.
  • the wipe Prior to impregnation with the composition of the invention, the wipe typically has an average thickness ranging from 0.1 to 3.0mm, preferably from 0.2 to 1.0mm, more preferably from 0.3 to 0.6mm.
  • the wipe Prior to impregnation with the composition of the invention, the wipe typically has a maximum absorbency of from 2 to 12g/g (grams water per gram of wipe), preferably from 3 to 10g/g, more preferably from 4 to 8g/g.
  • the wipe Prior to impregnation with the composition of the invention, the wipe typically has a baseweight of from 30 to 100 g/sq m, preferably from 40 to 90 g/sq m, more preferably from 50 to 80 g/sq m.
  • the wipe of the invention has on one side a textured abrasive surface formed from nodules and/or striations of abrasive material applied thereon, the abrasive material having a hardness ranging from 40 to 100 Shore D units.
  • abrasive refers to a surface texture that enables the wipe to produce a mild scouring or abrading action to effectively break up and remove dirt or other contaminants. Such dirt or contaminants are frequently embedded in a surface.
  • Shore D hardness is measured at 20°C using the procedures explained in ISO R 868.
  • a suitable instrument is the Bareiss HHP 2000 Shore Hardness tester.
  • Synthetic polymeric abrasive materials are especially useful. Most preferred are those having a hardness ranging from 40 to 100 Shore D units, preferably from 50 to 95 Shore D units, more preferably from 70 to 90 Shore D units.
  • Suitable synthetic polymeric abrasive materials of the appropriate Shore D hardness range as defined above include polyolefins, polyesters, polyvinyl chlorides, and polyamides. Copolymers or mixtures of any of these may also be suitable. Specific examples include polyethylene, polypropylene, polybutylene, polyethylene terephthalate, poly (ethylene) vinyl acetate, polystyrene, polyamide, polymethyl methacrylate, and polyvinyl chloride.
  • the nodules and/or striations of abrasive material may be distributed on the wipe substrate in a uniform pattern (such as polka dots) or an irregular distribution (such as speckles or streaks), depending on the method used to apply the abrasive to the wipe.
  • the abrasive material may suitably be dyed or pigmented. Preferably it is in a different colour to the wipe substrate on which it is present, so as to provide a visual indicator of its presence. In this way the user can readily distinguish between the non-abrasive and abrasive sides of the wipe.
  • the extent of surface coverage per unit area of the wipe substrate by the abrasive material typically ranges from 10 to 50%, preferably from 15 to 45%, more preferably from 20 to 40%, when measured by image analysis of the wipe.
  • the abrasive material may be applied to the wipe in a number of different ways known to those skilled in the art.
  • the abrasive material may be applied directly following extrusion of the fibres used to form the wipe.
  • the abrasive material is then embedded in the molten surface and becomes locked in place as the fibres cool.
  • the abrasive material is typically held in place on the substrate by means of an adhesive.
  • the adhesive and abrasive material may be applied to the wipe substrate by any suitable method. Roller coating and screen printing both give good results.
  • a solution or dispersion of the adhesive containing dispersed abrasive particles may be sprayed onto the wipe substrate and subsequently heat-cured.
  • abrasive particles may be formed in situ on the wipe substrate by spraying or sputtering molten or dissolved polymer onto the substrate.
  • Another suitable method is described in WO97/21865, according to which an abrasive nonwoven fibrous web material is produced by firstly forming a nonabrasive precursor web of nonwoven fibrous material.
  • the precursor web carries on one surface a uniform distribution of attenuated meltable thermoplastic fibres, such as polypropylene fibres.
  • the precursor web is then heated sufficiently to cause the attenuated thermoplastic fibres to shrink and form nodulated fibre remnants that impart a roughened abrasive character to the planar surface of the resultant web material. Because the fibres nodulate in situ, after being integrated within the web, this permits the formation of a single layer structure.
  • Wipes according to the invention incorporate an aqueous hard surface cleaning composition as defined above and referred to herein as "the composition of the invention”.
  • the weight ratio of composition of the invention to wipe suitably ranges from 1:1 to 6:1, and is preferably from 1:1 to 4:1, more preferably from 2:1 to 3:1.
