  • Wet wipes are typically pre-moistened, disposable towelettes which may be utilised in a variety of applications both domestic and industrial and perform a variety of functions.
  • Wet wipes are typically used to wipe surfaces both animate and inanimate, and may provide numerous benefits such as cleaning, cleansing, disinfecting, and skin care benefits.
  • wet wipes are wiping and or cleaning hard surfaces and the application of compositions to hard surfaces, for example kitchen and bathroom surfaces, eyeglasses, shoes and surfaces which require cleaning in industry for example surfaces of machinery or automobiles.

  • cleaning compositions available to be incorporated in a wet wipe, those relying on high levels of solvents, such as ethanol and other short chain monohydric alcohols, are often preferred, mainly due to the fast evaporation of said cleaning composition once it is applied onto the surface to be cleaned.
  • a drawback associated with the use of wet wipes incorporating a high level of solvents-containing cleaning composition is that there are some limitations to the convenience, especially regarding the insufficient wetting capabilities, of said wet wipes.
  • Insufficient wetting means that the cleaning composition forms single droplets on a surface, instead of a film, when applied thereon and/or forms droplets on said surface during drying, resulting in a reduced cleaning performance and/or visible residues (streaks) after drying.
  • the wetting capability and, thus the streak-free cleaning and/or the cleaning performance of said wet wipes incorporating a cleaning composition may be improved.
  • the objective of the present invention is to provide a wet wipe incorporating a cleaning composition showing wetting capabilities and, thus a streak-free cleaning benefit and/or a cleaning performance benefit on a wide range of stains and surfaces whilst delivering an evaporation benefit.

  • polyacetal carboxylates are the polyacetal carboxylates disclosed in U.S. Patent 4,144,226, Crutchfield et al., issued March 13, 1979, incorporated herein by reference. These polyacetal carboxylates can be prepared by bringing together, under polymerisation conditions, an ester of glyoxylic acid and a polymerisation initiator. The resulting polyacetal carboxylate ester is then attached to chemically stable end groups to stabilise the polyacetal carboxylate against rapid depolymerization in alkaline solution, converted to the corresponding salt, and added to a surfactant.
  • Polycarboxylate builders are also disclosed in U.S. Patent 3,308,067, Diehl, issued March 7, 1967, incorporated herein by reference. Such materials include the water-soluble salts of homo- and copolymers of aliphatic carboxylic acids such as maleic acid, itaconic acid, mesaconic acid, fumaric acid, aconitic acid, citraconic acid and methylenemalonic acid.
  • Suitable polyphosphonates for use herein are the alkali metal, ammonium and alkanolammonium salts of polyphosphates (exemplified by the tripolyphosphates, pyrophosphates, and glassy polymeric meta-phosphates), phosphonates.
  • the most preferred builder for use herein is citrate.
  • compositions according to the present invention may further comprise a divalent ion, or mixtures thereof.
  • All divalent ions known to those skilled in the art may be used herein.
  • Preferred divalent ions to be used herein are calcium, zinc, cadmium, nickel, copper, cobalt, zirconium, chromium and/or magnesium and more preferred are calcium, zinc and/or magnesium.
  • Said divalent ions may be added in the form of salts for example as chloride, acetate, sulphate, formate and/or nitrate or as a complex metal salt.
  • calcium may be added in the form of calcium chloride, magnesium as magnesium acetate or magnesium sulphate and zinc as zinc chloride.
  • such ions may be present at a level up to 3 %, preferably from 0.001% to 1% by weight of the total composition.
  • liquid compositions herein may also comprise a bleaching component. Any bleach known to those skilled in the art may be suitable to be used herein including any peroxygen bleach as well as a chlorine releasing component.
  • Suitable peroxygen bleaches for use herein include hydrogen peroxide or sources thereof.
  • a source of hydrogen peroxide refers to any compound which produces active oxygen when said compound is in contact with water.
  • Suitable water-soluble sources of hydrogen peroxide for use herein include percarbonates, preformed percarboxylic acids, persilicates, persulphates, perborates, organic and inorganic peroxides and/or hydroperoxides.
  • Suitable chlorine releasing component for use herein is an alkali metal hypochlorite.
  • the composition of the invention are stable in presence of this bleaching component.
  • alkali metal hypochlorites are preferred, other hypochlorite compounds may also be used herein and can be selected from calcium and magnesium hypochlorite.
  • a preferred alkali metal hypochlorite for use herein is sodium hypochlorite.
  • compositions of the present invention that comprise a peroxygen bleach may further comprise a bleach activator or mixtures thereof.
  • bleach activator it is meant herein a compound which reacts with peroxygen bleach like hydrogen peroxide to form a peracid. The peracid thus formed constitutes the activated bleach.
  • Suitable bleach activators to be used herein include those belonging to the class of esters, amides, imides, or anhydrides. Examples of suitable compounds of this type are disclosed in British Patent GB 1 586 769 and GB 2 143 231 and a method for their formation into a prilled form is described in European Published Patent Application EP-A-62 523.
  • Suitable examples of such compounds to be used herein are tetracetyl ethylene diamine (TAED), sodium 3,5,5 trimethyl hexanoyloxybenzene sulphonate, diperoxy dodecanoic acid as described for instance in US 4 818 425 and nonylamide of peroxyadipic acid as described for instance in US 4 259 201 and n-nonanoyloxybenzenesulphonate (NOBS).
  • TAED tetracetyl ethylene diamine
  • NOBS n-nonanoyloxybenzenesulphonate
  • N-acyl caprolactams selected from the group consisting of substituted or unsubstituted benzoyl caprolactam, octanoyl caprolactam, nonanoyl caprolactam, hexanoyl caprolactam, decanoyl caprolactam, undecenoyl caprolactam, formyl caprolactam, acetyl caprolactam, propanoyl caprolactam, butanoyl caprolactam pentanoyl caprolactam or mixtures thereof.
  • a particular family of bleach activators of interest was disclosed in EP 624 154, and particularly preferred in that family is acetyl triethyl citrate (ATC).
  • Acetyl triethyl citrate has the advantage that it is environmental-friendly as it eventually degrades into citric acid and alcohol. Furthermore, acetyl triethyl citrate has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally, it provides good building capacity to the composition.
