Definitions

  • This invention relates to a package containing a powdered detergent, more particularly to a gas and/or vapour tight package.
  • powdered detergents have always been packed as loose powder, i.e. the contents of the package were, at least partly, filled with air. Also because of the low density of powdered detergents, such packages occupy a large volume.
  • One object of the invention is to provide a package containing a powdered detergent which occupies little volume, without necessarily using the high-density formulation for the powdered detergent.
  • the invention relates to a package containing a powdered detergent, which is characterized in that the powdered detergent is packed in compressed form in a gas and/or vapour tight foil.
  • the invention basically comprises three variants of packaging detergents utilizing compression, namely under vacuum, in a shrink-foil or under external overpressure.
  • the detergent is compressed, so that it occupies a minimal volume and does not set during storage and transport.
  • the detergent is packaged under vacuum, which means that a vacuum is produced after filling of the package, so that the powder is compressed after the package has been closed.
  • This system has long been known for the packaging of ground coffee.
  • a requirement for this variant is that the foil should be reasonably gas tight.
  • an underpressure of 0.1 to 0.9 bar is used in this package.
  • a shrink-foil is used.
  • the powder is packaged in a foil, which is heated after packaging and then shrinks, thereby compressing the powder.
  • the package can be sealed hermetically. However, this is not necessary.
  • the third variant of the invention comprises packaging the powder under pressure.
  • a particular requirement for the package in this variant is that it must be resistant to the forces generated as a result of the pressure applied.
  • the overpressure employed preferably ranges from 0.5 to 15 bar.
  • a surprising advantage of the invention is that for packaging, relatively inexpensive, and often environment-friendly, materials can be used, such as paper or synthetic foils, for example surlyn foil, polypropylene foil or polyethylene foil, optionally coated and/or laminated with a lacquer, nylon, polyester or aluminum.
  • the invention can be used for all types of powdered detergents.
  • the powdered detergent preferably consists of agglomerates which are composed of a core, in which the more hygroscopic ingredients are located, and a shell, in which the less hygroscopic ingredients are located.
  • Suitable powdered detergents to be used in the package of the invention consist of agglomerates having a core, in which the more hygroscopic ingredients are located, and a shell, in which the less hygroscopic ingredients are located.
  • More particularly detergent-active agents and bleaching agents are located in the core, while bicarbonate is incorporated in the shell.
  • the shell can also contain a metal soap.
  • the proportions of the amounts of the core and the shell can vary within broad limits. These proportions also depend strongly on the composition of the detergent. In general, the core constitutes about 20-80% by weight of the total detergent and the shell about 20-80% by weight.
  • the detergent consists of 0.1 - 3 parts by height of metal soap 5 - 30 parts by weight of detergent 0 - 20 parts by weight of sodium perborate, 0 - 5 parts by weight of other components and 20 - 65 parts by weight of sodium bicarbonate.
  • the detergent agents used are preferably anionic or nonionic detergents, such as fatty alcohol ethoxylate and/or sodium dodecyl benzene sulfonate. More particularly fatty alcohol ethoxylate and sodium dodecyl benzene sulfonate are used in equal amounts by weight.
  • a bleaching agent preferably sodium perborate is used, preferably with 4 molecules of water of crystallization, although the modification with one molecule of water of crystallization can also be used.
  • supplementary additives may be used as well, as is conventional for powdered detergents of the present type.
  • supplementary additives are colourings, optical whitening agents, perfume, enzymes and the like.
  • the preferred powdered detergent may be produced by a processs, which comprises agglomerating a part of the components of the detergent to form primary agglomerates, followed by agglomerating said primary agglomerates with the remaining component(s).
  • the more hygroscopic components are agglomerated to form primary agglomerates, whereupon these primary agglomerates are agglomerated with the less hygroscopic components.
  • This method can be carried out in the conventional apparatus for powdered detergents, using the conventional conditions.
  • Example 1 An enzymatic soaking detergent
  • I II A Sodium bicarbonate 60 60 B Sodium lauryl sulfate 15 15 C Fatty alcohol ethoxylate 7EO 10 10 D Fatty alcohol ethoxylate 25EO 10 10 E Protease granulate 1 1 F Cellulase granulate 1 1 G Minors including perfume, and silicon oxide 3 3 H Sodium sulfate 30 100 130
  • the dose for I is 90 g detergent for a normal washing machine load that is to be soaked.
  • the dose for II is 130 grams.
  • the sodium sulfate together with half the amount of the sodium bicarbonate is initially present.
  • the product formed is stored in a closed vessel in a room of low humidity.
  • the temperature of the room is 15°C and the humidity is less than 40%.
  • the cooled product is finally packaged in a vacuum-packaging machine in an externally lacquered polyethylene foil package, formed in the machine.
  • Example 2 An enzymatic prewash detergent
  • I II A Sodium bicarbonate 39 39 B Sodium carbonate 19 19 C Sodium lauryl sulfate 10 10 D Fatty alcohol ethoxylate 7EO 10 10 E Fatty alcohol ethoxylate 25EO 15 15 F Protease granulate 1 1 G Amylase granulate 1 1 H Minors including perfume, copolymers and tertiary amine (for foam inhibition) 5 5 I Sodium sulfate 30 100 130
  • the dose for I is 60 g detergent for a normal washing machine load that is to be soaked.
  • the dose for II is 87 g.
  • the total amount of B and half the amount of A is applied to a fluid bed apparatus. Added thereto is the mixture of D and E in a melted state, so finely divided and so slowly that a pulpy, granular product is obtained. During the subsequent cooling period, C is added first, and then the enzyme granulates and the residue of A and the minors are admixed.
  • the sodium sulfate together with half of the amount of the sodium carbonate is initially present.
  • the product formed is cooled in a closed vessel in a room of low humidity.
  • the temperature of the room is 15°C and the humidity is less than 40%.
  • the cooled product is finally packaged in a vacuum-packaging machine in a package that is formed in the machine from a polyethylene foil coated with aluminum.
  • Example 3 An enzymatic soaking detergent

After C, D and F have been added, E, heated to about 90°C, is added so slowly that a product of the desired grain size is obtained.
