Definitions

  • the present invention relates to a method for washing textile fabrics using a non-aqueous liquid detergent with separate bleach in a household washing machine and to a mixing and metering device which is used in this method.
  • liquid detergents generally contain anionic and nonionic surfactants and water as a solvent.
  • the incorporation of bleaching agent systems into these liquid detergents has proven to be difficult since the bleaching agent decomposes very easily in the presence of water.
  • the bleaching agents in particular percarbonates, will clump when incorporated into the liquid formulations. These clumps can lead to high bleach concentrations locally, which can lead to spotting problems, particularly in the case of colored textiles, and thus a uniform bleaching performance in the wash liquor would no longer be guaranteed.
  • European patent application 30 096 discloses non-aqueous liquid detergents made from liquid nonionic surfactants, which can contain 20 to 70% by weight builder substances and 1 to 20% by weight bleach in suspended form.
  • anionic surfactants such as alkylbenzenesulfonates, olefin sulfonates, alkyl sulfates or soap, optical brighteners, dyes, fragrances or enzymes can be added to these agents.
  • the bleaching agent has a particle size that no more than 30% of the particles are larger than 5 ⁇ m and particularly preferably no more than 10% larger than 10 ⁇ m.
  • EP-B-0 460 810 describes a non-aqueous, liquid detergent composition for dishwashers which selects a non-aqueous, organic carrier liquid and at least one constituent selected from organic detergent, detergent builder, foam inhibitor and mixtures thereof, and a constituent from a non-abrasive amount of 0.5 to 10% of small, essentially water-insoluble particles of silicon dioxide, aluminum oxide or titanium oxide or mixtures thereof as anti-film-forming agents.
  • the agent described may further contain 3 to 15% by weight of bleach
  • WO 94/01524 describes an essentially non-aqueous liquid detergent which, in addition to nonionic surfactant, contains up to 60% by weight of builder substance and between 5 and 35% by weight of bleach.
  • the liquid detergent composition described also contains a polymer compound which reduces the viscosity of the dispersion of the solid builders and bleaches in the nonionic surfactant in order to obtain a flowable and pourable composition.
  • German patent application 36 26 572 describes a liquid detergent which contains builder substance, in particular polyacetal carboxylate, an agent which prevents gel formation and an agent which prevents settling, dispersed in a liquid nonionic surfactant.
  • the solid particles should preferably have a particle size that no more than 10% of the particles are larger than 10 ⁇ m.
  • So-called modular systems are also known on the market as an alternative to the detergents and cleaning agents consisting of several components.
  • the individual system components which are generally in the form of solids, are metered in via the addition compartment of the washing machine and mixed in the washing drum.
  • liquid components such as a liquid detergent without bleach and bleach present in solid form
  • EP-A-0 288 345, EP-A-0 288 346 and EP-A-0 331 542 describe two-part containers in which a preferably liquid cleaning agent and one not with the cleaning agent are in each case provided via separate openings compatible additive, for example a bleach, are also preferably given in liquid form.
  • the described containers consist of a larger container into which a further container or bag is inserted. Both containers or departments can be filled separately with the corresponding liquids.
  • the filled container described in the above-mentioned documents is placed in the washing drum of a conventional household washing machine, and during the washing process the liquid components diffuse into the drum and are mixed there.
  • this device has the disadvantage that the bleaching agent can only be uniformly dispensed in liquid form.
  • the bleach is released undiluted and it can lead to spotting if it comes into direct contact with the laundry.
  • Another economic and ecological disadvantage of this container is that it is only intended for single use.
  • German utility model G 880 920.9 discloses a metering memory for receiving and dispensing laundry treatment agents, in particular liquid laundry treatment agents, in a washing machine or the like, which has at least two liquid-tight receiving chambers, each having at least one dispensing opening.
  • the individual receiving chambers can contain various laundry treatment agents, such as are present, for example, as so-called “modular detergents”.
  • module detergents With two receiving chambers, for example, one can hold a liquid laundry treatment agent and another the bleaching component.
  • the substances are released into the wash water separately through the respective discharge openings of the dosing reservoir.
  • existing bleaching agent is dispensed into the washing drum as an undiluted substance, which in turn can cause the "spotting problems" described above.
  • the object of the present invention was to provide a method for washing textile fabrics using a non-aqueous liquid detergent with bleach in a household washing machine which does not have the above disadvantages.
  • Another object of the present invention is to provide a metering device which makes it possible to use two incompatible, i.e. dosing detergent components that can be stored together in a recipe for a long time separately in a single device, then mixing in this device and metering the mixture obtained directly into the washing machine.

  • bleach-containing component B can be mixed in a simple manner with the liquid component A in the amount usually required for domestic washing machines and thus a non-aqueous liquid detergent with bleach. It was found that the disadvantages described in the prior art are not observed when this liquid detergent produced directly before the wash cycle is used.
  • the method according to the invention for washing textile fabrics leads essentially to the same results as the known powdery universal detergents which contain bleaching agents.

Abstract

La présente invention concerne un procédé de lavage de textiles dans une machine à laver domestique mettant en ÷uvre un produit lessiviel liquide non aqueux avec agent de blanchiment séparé. Ce procédé est caractérisé en ce que le produit lessiviel liquide non aqueux avec agent de blanchiment comprend au moins deux composants: le composant A contient un tensio-actif liquide ou un mélange tensio-actif liquide, et le composant B contient l'agent de blanchiment à mélanger avant lavage et à mettre dans la machine. L'invention porte aussi sur un dispositif mélangeur et doseur pour produits lessiviels à composants multiples, qui comprend plusieurs compartiments (1, 2) pouvant être reliés entre eux par un dispositif de verrouillage (8) par déplacement et par rotation. Ces compartiments (1, 2) présentent, sur leur surface (4, 5) adjacente à un compartiment voisin, des ouvertures (6, 6' et 7, 7') pouvant être placées en alignement par déplacement ou rotation des compartiments (1, 2). Ce procédé et ce dispositif permettent d'obtenir un produit lessiviel à agent de blanchiment uniformément réparti, de sorte qu'il peut être ajouté au linge sans formation de taches.
