Definitions

  • the invention relates to a perfumed water-softener composition in powdered form which contains an effervescent system.
  • Cleaning agents and water-softener compositions often contain a perfume or perfume mixture, intended to impart a pleasant fragrance to items to be cleaned, such as laundry, and/or intended to release a fragrance that is pleasant to the user during the washing process, for example, when washing laundry by hand.
  • effervescent systems in detergent compositions - particularly these are in a tablet form - in order to accelerate dissolution in the washing water is known. Examples of this are described in WO98/46714, WO98/45283 or WO98/04667 which compositions contain surfactants and/or bleaching agents.
  • the underlying objective of the invention is to improve water-softener compositions, preferably in powdered form (powder water softener compositions), so that they produce a perfume effect sustained for a long period during its use.
  • a water-softener composition preferably in powdered form, containing at least one perfume, the composition also containing an effervescent system.
  • the water-softening composition should be essentially free of any surfactant and bleaching agent.
  • the effervescent system contains at least one alkali metal carbonate and/or alkali hydrogen carbonate and at least one acidifying agent, the acidifying agent preferably containing at least one acid, most preferably an organic carboxylic acid.
  • the organic carboxylic acid is a fruit acid, preferably citric acid or malic acid.
  • the invention also relates to the use of an effervescent system, preferably one as described above, used in water-softener compositions, preferably in the form of a powder, containing at least one perfume, to improve the durability of the fragrance given off by this perfume.
  • the invention relates to the use of water-softener compositions, preferably in the form of a powder for applications involving manual laundering.
  • This effect can be regarded as positive with all conceivable water-softener compositions, it is of particular advantage for those in which the duration of the fragrancing effect of the perfume or the perfume mixture is particularly perceptible, i.e. in cases where the composition is deployed in such a way that the user is immediately aware of the perfume effect, such as when used for manual laundering, for example.
  • One particularly preferred application is the addition of an effervescent system to a water-softener composition in a powder form displaced with a fragrance for use in manual laundering, which is preferably added to the washing liquid prior to adding the actual washing agent, in order to enhance the cleansing effect. Tests to date have therefore mainly been conducted on compositions of this type.
  • the system comprising sodium hydrogen carbonate and citric acid
  • the effervescent system in the example described below, it would, of course, also be possible to consider other effervescent systems, in particular those containing other acids, such as polymeric acids or glycolic acid, lactic acid, etc. Tests have shown that the effervescent system as such is not critical to the described effect. On the contrary, there is considerable flexibility, which means that a selection can be made to suit specific circumstances for the use of the water-softening composition.
  • Preferred amounts of acidifying agent are present in the composition in the range of 0.51% w/w to 25% w/w, ideally 1% w/w to 20% w/w, preferably 2% w/w to 10% w/w and especially 2% w/w to 6% w/w.
  • a preferred acidifying agent is citric acid.
  • alkali metal carbonate and/or hydrogen carbonate are present in the composition in the range of 4% w/w to 70% w/w, ideally 15% w/w to 65% w/w, preferably 25% w/w to 60% w/w and especially 40% w/w to 58% w/w.
  • the water softening component of the composition may contain any known water softening compound or mixture, such as water soluble water-softening agent or a water-insoluble water-softening agent, notably alkali-metal aluminosilicate.
  • Water soluble water-softening agent may be organic or inorganic.
  • Inorganic may be present include alkali metal (generally sodium) carbonate; while organic 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.
  • 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.
  • composition contains only soluble water-softening agent, this may well be a salt of tripolyphosphate and/or ditric acid, such as the sodium salt, and/or a condensed phosphate.
  • Suitable crystalline sodium aluminosilicate ion-exchange detergency builders are described, for example, in GB 1429143 (Procter & Gamble).
  • the preferred sodium aluminosilicates of this type are the well known commercially available zeolites A and X, and mixtures thereof.
  • Also of interest is the novel zeolite P described and claimed in EP 384070 (Unilever).
  • water-insoluble material which can function as a water-softening agent is the layered sodium silicate builders disclosed in US-A-4464839 and US-A-4820439 and also referred to in EP-A-551375.
  • water-soluble water-softening agent as described above, jointly with aluminosilicate, to enhance water-softening efficacy.
  • Such water-soluble soluble water-softening agent are generally used in an amount which is not greater than the amount of aluminosilicate, often less than half the amount of aluminosilicate.
  • Preferred amounts of the water-softening component are present in the composition in the range of 4% w/w to 65% w/w, ideally 15% w/w to 60% w/w, preferably 25% to 55% w/w and especially 35% w/w to 48% w/w.
  • the amount of perfume added to the composition is dependent upon the desired effect wanted to be achieved. Typical amounts may be from 0.05% w/w to 2% w/w.
  • composition is preferbly in the form of a powder, however other solid formulations are contemplated such as tablets, either made by compaction or by extruding.
  • Liquid formulations may also be used in which the ingredients may be suspended or dissolved in a nonaqueous liquid carrier medium, such liquid media include;
  • composition of samples I to IV is set out more specifically in Table I below.
  • Table I Sodium tripolyphosphate Sodium hydrogen carbonate Citric acid Fragrance I 42.53 44.88 12.00 0.12 II 42.53 50.88 6.00 0.12 III 42.53 53.88 3.00 0.12 IV 42.54 56.88 - 0.12
