Definitions

  • This invention relates to water soluble detergent sachets comprising a detergent composition, in particular a laundry detergent or machine dishwashing composition.
  • detergent compositions especially laundry detergent compositions
  • the consumer is required to determine and provide the correct dosage of the product at the point of use. This may lead to over dosing of the product and/or to an increased risk of spillage or wastage.
  • detergent products have been commercially available in a form which provide a single dose of the detergent product for the consumer to add directly to the cleaning operation.
  • Two examples of these single-dose products are laundry detergent tablets of compressed powder and water-soluble sachets of detergent composition which may contain the detergent product in liquid, paste or particulate form.
  • Water-soluble sachets generally comprise a detergent composition encapsulated with water-soluble film, such as polyvinyl alcohol. Encapsulation allows for handling of the product without direct contact with the detergent composition. This is especially advantageous when the detergent composition comprises aggressive cleaning components which could irritate the skin on direct contact.
  • EP-A-479 404 (Unilever) describes a sachet or bag containing a cleaning composition wherein the sachet or bag is made of a continuous base film soluble in water with a second plastics material present as a discontinuous layer and which is less soluble than the base film material.
  • EP-A-253 566 (Procter & Gamble) describes a laundry product which comprises a particulate laundry composition releasably contained within a sachet formed of a film of water-soluble material, said film having an outer covering of a flexible, apertured, water-insoluble but water permeable non-woven, textile or paper sheet material.
  • US 4 410 441 discloses detergent sachets for particulate material where the sachets have pores and the particle size of the particulate material is chosen so that the amount of material which can escape through the pores is minimised.
  • a problem encountered with water soluble sachets containing a detergent composition is that the dissolution properties of the composition are sometimes hindered, especially the speed of dissolution, compared to the same detergent composition used without the sachet.
  • This effect of reduced dissolution has been found to be less apparent in conventional methods of introducing a particulate detergent composition into a cleaning operation.
  • particulate detergent compositions used with a conventional dispensing device such as a detergent ball allow a good flow of water to pass through the dispensing device directly to the particulate detergent composition.
  • the present invention provides a water-soluble sachet containing a detergent composition which has adequate dissolution properties, adequate seal strength and allows the migration of perfume smells and other gaseous substances to the outside of the sachet without a need to puncture the sachet.
  • the invention relates to a process according to present claim 1.
  • the detergent composition may be any type of detergent composition for which it is desirable to provide a single dose thereof in a water soluble sachet.
  • the detergent composition may be in the form of tablets or briquets.
  • the detergent composition is a particulate detergent composition for example having an average mean particle size of from 400 to 4000 micron.
  • the detergent composition may be a laundry (fabric cleaning, softening and/or treatment) composition or a machine dishwashing detergent composition.
  • detergent sachets are suitable for use in (fabric) washing machines and in dishwashing machines amongst other applications. They can also be used in the manual laundry and dishwashing operations.
  • the detergent composition may contain particles which have been prepared by spray-drying or granulation and which contain a mixture of ingredients. Such particles may contain organic detergent surfactant and some, or all, of any water-softening agent (detergency builder) present in the composition. Suitable granulation and spray drying methods are well known in the art. The spray dried or granulated particles may be optionally mixed with other materials to form the particulate detergent composition.
  • the particulate detergent composition may have a bulk density of at least 400 g/litre, preferably at least 500 g/litre, and most preferably at least 600 g/litre.
  • the detergent compositions typically comprise one or more organic surfactants.
  • organic surfactants Many 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 surfactant may be anionic (soap or non-soap), cationic, zwitterionic, amphoteric, nonionic or a combination of these.
  • the preferred detergent-active compounds that can be used are soaps and synthetic non-soap anionic and nonionic compounds.
  • Anionic surfactant may be present in an amount from 0.5 to 50% by weight, preferably from 2% or 4% up to 30% or 40% by weight of the composition.
  • Suitable examples include alkyl benzene sulphonates, particularly sodium linear alkyl benzene sulphonates having an alkyl chain length of C 8 -C 15 ; olefin sulphonates; alkane sulphonates; dialkyl sulphosuccinates; and fatty acid ester sulphonates.
  • Suitable nonionic surfactant compounds include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example, aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide.
  • Nonionic surfactant compounds are alkyl (C 8-22 ) phenolethylene oxide condensates, the condensation products of linear or branched aliphatic C 8-20 primary or secondary alcohols with ethylene oxide, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylene-diamine.
  • these organic surfactants preferably provide from 5 to 50% by weight of the overall composition.
  • organic surfactant is likely to constitute from 0.5 to 8% by weight of the overall composition and is likely to consist of nonionic surfactant, either alone or in a mixture with anionic surfactant.
  • the detergent compositions may contain a so-called water-softening agent, which serves to remove or sequester calcium and/or magnesium ions in the water.
  • a water-softening agent is more usually referred to as a detergency builder.
  • the amount of it is likely to lie in a broad range from 5%, preferably 15 wt% up to 98% by weight of the composition.
  • the amount is likely to be from 15 to 80% by weight, more usually 15 to 60% of the composition.
  • Water-softening agents may be provided wholly by water soluble materials, or may be provided in large part or even entirely by water-insoluble material with water-softening properties.
  • Alkali metal aluminosilicates are strongly favoured as environmentally acceptable detergency builders for fabric washing.
  • Suitable crystalline sodium aluminosilicate ionexchange materials are described, for example, in GB 1 429 143 (Procter & Gamble).
  • the preferred sodium aluminosilicates of this type are the well known commercially available zeolites A and X, the newer zeolite P described and claimed in EP 384 070 (Unilever) and mixtures thereof.
  • This form of zeolite P is also referred to as "zeolite MAP".
  • zeolite A24 Ex Ineos Silicas, UK).
  • the builder may also be a water-soluble phosphorus-containing inorganic softener for example alkali-metal orthophosphates, metaphosphates, pyrophosphates and polyphosphates.
  • inorganic phosphate detergency builders include sodium and potassium tripolyphosphates, orthophosphates and hexametaphosphates.
  • Non-phosphorus water-soluble detergency builders may be organic or inorganic.
  • Inorganics that may be present include alkali metal (generally sodium) carbonate; while organics include polycarboxylate polymers, such as polyacrylates, acrylic/maleic copolymers, and acrylic phosphonates, monomeric polycarboxylates such as citrates, gluconates, oxydisuccinates, glycerol mono- di- and trisuccinates, carboxymethyloxysuccinates, carboxymethyloxymalonates, dipicolinates and hydroxyethyliminodiacetates.

  • the detergent compositions according to the invention may contain a bleach system.
  • a bleach system preferably comprises one or more peroxy bleach compounds, for example, inorganic persalts or organic peroxyacids, which may be employed in conjunction with activators to improve bleaching action at low wash temperatures. If any peroxygen compound is present, the amount is likely to lie in a range from 10 to 85% by weight of the composition. If the composition contains surfactant and detergency builder, the amount of peroxygen compound bleach is unlikely to exceed 25%wt of the composition.
  • Preferred inorganic persalts are sodium perborate monohydrate and tetrahydrate, and sodium percarbonate, advantageously employed together with an activator.
  • Bleach activators also referred to as bleach precursors, have been widely disclosed in the art.
  • Detergency enzymes may be employed in the compositions and are commonly employed in the form of granules or marumes, optionally with a protective coating, in amount of from about 0.1% to about 3.0% by weight of the composition.
  • compositions may also contain a fluorescer (optical brightener), for example, Tinopal (Trade Mark) DMS or Tinopal CBS available from Ciba-Geigy AG, Basel, Switzerland.
