Definitions

  • the present invention relates to an antimicrobial wipe which is designed in particular for the hygienic cleaning of surfaces, such as hard surfaces in the household, or in institutional or hospital environments, or the surface of the skin, or fabric surfaces.
  • the wipe contains an antimicrobially active mixture of anionic surfactant and acid, in combination with a specific solvent, and shows improved hygienic cleaning performance.
  • Cleaning compositions designed for application to surfaces generally comprise one or more surfactants, and, optionally, one or more antimicrobial actives and/or solvents .
  • Such surfaces are often contaminated with bacteria and other micro-organisms, which present a risk to human health, especially when they are present near food.
  • the biocidal activity of surfactants is, with a few notable exceptions, low and it is therefore commonplace to add a separate antimicrobial active to compositions.
  • the antimicrobial effectiveness of organic acids is known in the literature. Organic acids are utilised in cleaning products to provide antimicrobial activity, but generally do not achieve a sufficient level of bacterial kill, especially when present in formulations at relatively low levels.
  • WO98/55096 discloses that improved germ reduction and improved residual effectiveness can be obtained in a skin cleansing antimicrobial wipe which is impregnated with a mixture of an anionic surfactant and a proton donating agent (such as organic acid) , by the addition of a further antibacterial active such as TRICLOSAN.
  • a wipe containing an antimicrobially active mixture of anionic surfactant and acid, in combination with a solvent which is an N-alkyl pyrrolidone derivative shows superior cleaning performance, particularly with respect to the removal of fatty soil, and gives excellent hygiene performance.
  • Wipes of this invention are particularly suited for the hygienic cleaning of surfaces such as hard surfaces in the household, or in institutional or hospital environments, or the surface of the skin, or fabric surfaces. Surprisingly they provide the requisite level of bacterial kill for this type of application without requiring the addition of any further antibacterial actives such as those described in WO98/55096.
  • W095/21238 describes an acidic microemulsion or acidic all- purpose cleaner for hard surfaces which removes soap scum, lime scale and grease which includes an anionic surfactant, at least one organic acid , such as a mono-, di-, or tri- carboxylic acid, and an N-alkyl-2-pyrrolidone .
  • the product is designed to be sprayed onto a surface which is subsequently wiped. There is no mention of antimicrobial efficacy.
  • US 5 470 508 discloses an aqueous oil removal/degreasing composition containing higher-alkyl pyrrolidone such as N- octyl pyrrolidone, anionic surfactant and water.
  • GB 2 230 791 refers to a propylene glycol based solvent, such as propylene glycol t-butyl ether, in combination with N-methyl-2-pyrrolidone, for the removal of grease and varnish from metallic surfaces such as automotive parts.
  • W098/55569 and WO98/55570 relate to aqueous hard surface cleaners with improved residue removal and reduced filming/streaking.
  • the compositions comprise a mixture of anionic surfactants, an organic solvent such as an alkylene glycol ether, and preferably include a l-alkyl-2-pyrrolidone for dispersal of fragrance oils and other insoluble organic materials in the compositions.
  • the compositions are buffered to pH greater than 6.5 with a nitrogenous buffer.
  • EP 0 598 257 describes a water-based solution for reclaiming paint from spray booths with an N-alkyl pyrrolidone, preferably N-methyl pyrrolidone, a surfactant, preferably nonionic, and an alkylene glycol monoalkyl ether such as tripropylene glycol mono methyl ether.
  • EP 0 273 594 discloses a disposable semi-moist wipe for touch-up or light duty cleaning of bathroom or kitchen soil, containing a liquid cleaning composition comprising anionic or nonionic surfactant, one or more solvents for oil and dirt such as N-methyl pyrrolidone and ethylene or propylene glycol ethers, and sufficient hydroxide compound to produce a composition pH of 8 to 12.
  • EP 0 690 906 describes a multi-surface cleaner for the removal of greasy residues comprising an amine oxide or quaternary ammonium salt surfactant and a polar organic compound of defined water solubility such as certain of the propylene glycol ethers and N-alkyl pyrrolidones .
  • US 5 332 526 provides an environmentally safe paint stripping composition comprising N-methyl-2-pyrrolidone and lower alkyl ethers of propylene glycol and dipropylene glycol .
  • the present invention provides an antimicrobial wipe suitable for the hygienic cleaning of surfaces, which comprises a substrate incorporating an aqueous composition comprising:
  • Wipes of the invention are especially suitable for the hygienic 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 microbial 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.
