Definitions

  • the present invention relates to a composition for the treatment of textiles.
  • One route to improving handwash performance is to try to improve the ingredients in the main wash detergent formulation.
  • Clays are often added in small quantities as softening ingredients in detergent wash formulations.
  • WO 01 44561 Unilever
  • cleaning performance can be enhanced by including clay in the rinse liquor. It is postulated that the clay remains on the clothes after they have dried and provides a sacrificial layer to which dirt adheres and so is more easily removed during subsequent washing the next time. This reduces a build-up of particulate soil on the textile.
  • the present inventors have now surprisingly discovered that the dispersion and deposition efficiency of such clays may be enhanced if accompanied by an alkali metal salt and organic acid which react together in solution to produce carbon dioxide gas. This may additionally act as a cue to the consumer, for example, to provide reassurance that some functional ingredient is present and effective in the liquor.
  • composition for treating textile fabrics which comprises:
  • composition for treating textile fabrics which comprises:
  • composition containing no more than 10 wt% synthetic non-soap surfactant.
  • Another aspect of the present invention provides a process for the treatment of textile fabrics, which comprises a step in which the textiles are immersed for at least 30 seconds in an aqueous solution of the composition defined above.
  • Another aspect of the invention provides the use of an alkali metal salt and an organic acid for enhancing the dispersion and/or deposition of clay onto a textile in an aqueous medium.
  • Another aspect of the invention provides for the use of an alkali metal salt, an organic acid and a crystalline clay mineral for the manufacture of a textile treatment composition, the composition upon addition to an aqueous medium generates carbon dioxide gas and aids the dispersion and/or deposition of the clay.
  • the crystalline clay mineral is present at a level of at least 10 wt%, preferably at least 20 wt%, more preferably at least 30 wt% and most preferably at least 40 wt%.
  • the crystalline clay mineral is preferably light coloured and has a reflectance of at least 60, preferably at least 70, more preferably at least 80 at a wavelength of 460 nm. Ideally the crystalline clay mineral is white.
  • the reflectance was measured on a Macbeth Colour-eye 7000A reflectometer, although other methods may also be suitable.
  • the crystalline clay may be any appropriate mineral and preferably is selected from one or more clays selected from bi-layer clays (e.g. china clay and halloysite) which may be dioctahedral clays (such as kaolin) or trioctahedral clays (such as antigorite and amesite) ; tri-layer clays such as smectite and hormite, bentonite, beidelite, nontronite, hectorite, attapulgite, pimelite, mica, muscovite and vermiculite as well as pyrophyllite/talc, willemseite and minnesotaite clays.
  • bi-layer clays e.g. china clay and halloysite
  • dioctahedral clays such as kaolin
  • trioctahedral clays such as antigorite and amesite
  • tri-layer clays such as smectite and hormite, benton
  • a preferred class of clays is bi-layer dioctahedral within which kaolin is especially preferred.
  • the number average particle diameter of the clay mineral particles should not exceed 5 ⁇ m, and preferably does not exceed 2 ⁇ m. This particle size
  • TM diameter is that measured by use of a Malvern Zetasizer , using a dispersion of the clay mineral at 0.1 g/1 in deionised water at 25°C, the clay being dispersed by vigorous hand agitation using a glass rod stirrer for 1 minute.
  • the alkali metal salt and the organic acid are capable of reacting together in solution to produce effervescent carbon dioxide gas and an electrolyte in solution.
  • the alkali metal salt is most preferably selected from carbonate, bicarbonate, sesquicarbonate and combinations thereof.
  • the alkali metal salt and the organic acid there is preferably a sufficient concentration of the alkali metal salt and the organic acid in order to provide an acceptable amount of effervescence.
  • the combined amounts of alkali metal salt and organic acid is at least 5 wt% of the total composition.
  • the combined amount is at least 10 wt% and more preferably at least 20 wt% of the total composition.
  • the alkali metal salt may have any suitable cation but it is preferred that it is a sodium salt.
  • the organic acid may be any suitable compound but is preferably non-hygroscopic, in order to improve storage stability.
  • the acid is preferably water-soluble. Suitable acids include citric, glutaric, succinic or adipic, however citric acid is preferred.
  • the weight ratio of the alkali metal salt (b) (i) to the organic acid (b) (ii) is in the range of from 10:1 to 1:5.
  • the produced effervescence enhances the dispersion and deposition of the clay onto the textile which has an effect above and beyond any enhanced dispersion and deposition effects due to the electrolyte produced. Furthermore the effervescence may provide a cue to the user that something special is happening, especially in a hand wash process. The effervescence may also enhance the efficacy of any perfumes which may be present .
  • the optional water-soluble salt is believed to be beneficial because it further promotes dispersion and assists flocculation of the clay particles in the treatment solution and enables them to be uniformly dispersed and so deposit more uniformly on the textile.
  • non-surfactant water-soluble salt Any non-surfactant water-soluble salt may be used.
  • non-surfactant salt is used because many surfactants, e.g. anionic surfactants are in the form of water soluble alkali metal salts and cationic surfactants are usually in water-soluble salt form with a counter-anion.
  • salts of the metal cations with inorganic or organic anions are appropriate.
  • a mixture of salts may also be used, but it is preferable to use a material which is widely available at low cost.
  • a soluble salt of a monovalent metal such as an alkali metal, for example sodium or potassium, e.g. as the chloride or sulphate.
  • weight for weight, it is more effective to use a salt of a divalent metal, or a water-soluble salt of a metal having a valency of three or more; the tetravalent tetrasodium pyrophosphate being especially preferred. It could also be a water-soluble detergency builder such as an alkali metal citrate or tripolyphosphate .
  • the salt may comprise any suitable level up to as much as 85 wt% of the full formulation. However, preferably the salt will be present at a level of from 5 to 20 wt%.
  • the treatment composition which has as components the clay, the alkali metal salt and the organic acid, may also contain other optional ingredients.
  • clays which do not have the required level of whiteness may still be used if a clay whitening ingredient is also included.
  • a whitening agent is a particulate material which is lightly coloured, preferably white. Examples of preferred whiteners are calcite, dolomite and titanium dioxide. Even if the clay is already white, such whiteners may still be included to ensure the clay remains white during storage before use by the consumer.
  • compositions of the present invention may contain no more than 10 wt% synthetic non-soap surfactant, preferably no more than 5 wt%, more preferably no more than 1 wt% and most preferably substantially zero wt%.
  • detergent- active compounds or surfactants may be chosen from soap and non-soap anionic, cationic, nonionic, amphoteric and zwitterionic detergent-active compounds, and mixtures thereof.
  • detergent-active compounds or surfactants may be chosen from soap and non-soap anionic, cationic, nonionic, amphoteric and zwitterionic detergent-active compounds, and mixtures thereof.
  • suitable detergent-active compounds are available and are fully described in the literature, for example, in "Surface-Active Agents and Detergents", Volumes I and II, by Schwartz, Perry and Berch.
  • the preferred detergent-active compounds are soaps and synthetic non-soap anionic and nonionic compounds .

  • Non- ethoxylated nonionic surfactants include alkylpolyglycosides, glycerol monoethers, and polyhydroxyamides (glucamide) .

Abstract

Cette invention se rapporte à une composition pour le traitement du linge contenant un minéral argileux cristallin, un sel métallique alcalin ainsi qu'un acide organique. Le sel et l'acide réagissent ensemble lorsque la composition est ajoutée à de l'eau afin qu'un gaz carbonique soit produit, lequel favorise la dispersion et/ou la déposition de l'argile sur les textiles. La couche sacrificielle d'argile rend le textile traité moins vulnérable à certaines salissures.
