Definitions

  • compositions which aim to improve dispensing characteristics of high bulk density detergents have also been described in the prior art.
  • EP-A-534525 published on 31st March, 1993 describes the use of particulate citric acid having a specified particle size in order to aid dispensing. Bleach compounds including percarbonate are mentioned. However, use of particulate citric acid does not address the problem of providing alkaline conditions in the wash liquor.
  • a granular detergent composition according to the invention is defined in claim 1.
  • a particularly useful component of the present invention is at least 0.5% by weight of a peracid precursor chosen from tetraacetyl methylene diamine, tetraacetyl ethylene diamine, tetraacetyl hexylene diamine, perbenzoic acid or hydrophobic peracid precursors such as 2-phenyl 4h-3 1-benzoxazin-4-one, NOBS, iso-NOBS, benzoylcaprolactam, benzoyloxybenzenesulphonate or mixtures thereof.
  • a peracid precursor chosen from tetraacetyl methylene diamine, tetraacetyl ethylene diamine, tetraacetyl hexylene diamine, perbenzoic acid or hydrophobic peracid precursors such as 2-phenyl 4h-3 1-benzoxazin-4-one, NOBS, iso-NOBS, benzoylcaprolactam, benzoyloxybenzenesulphonate or mixture
  • Such silicates may be characterised by the ratio of SiO 2 to Na 2 O in their structure. In the present invention, this ratio may typically be less than 3.3:1, preferably less than 2.8:1, more preferably less than 2.4:1, most preferably about 2.0:1.
  • compositions of the present invention will include a percarbonate bleach, normally in the form of the sodium salt, as the source of alkaline hydrogen peroxide in the wash liquor.
  • This percarbonate is normally incorporated at a level of up to 25% by weight of the total composition.
  • Particularly preferred precursor compounds are the N-,N,N 1 N 1 tetra acetylated compounds of formula wherein x can be O or an integer between 1 & 6.
  • Cationic surfactants can also be used in the detergent compositions herein and suitable quaternary ammonium surfactants are selected from mono C 8 -C 16 , preferably C 10 -C 14 N-alkyl or alkenyl ammonium surfactants wherein remaining N positions are substituted by methyl, hydroxyethyl or hydroxypropyl groups.
  • the surfactant containing particles will further comprise components selected from a wide range of possible ingredients which are commonly used in laundry detergents.
  • the particles will contain some detergent builder:
  • the builder system is present in an amount of from 25% to 60% by weight of the composition, more preferably from 30% to 60% by weight.
  • Preferred builder systems are free of boron compounds and any polymeric organic materials are preferably biodegradable.
  • Polycarboxylates containing three carboxy groups include, in particular, water-soluble citrates or citric acid, aconitrates and citraconates as well as succinate derivatives such as the carboxymethyloxysuccinates described in British Patent No. 1,379,241 , lactoxysuccinates described in British Patent No. 1,389,732 , and aminosuccinates described in Netherlands Application 7205873 , and the oxypolycarboxylate materials such as 2-oxa-1,1,3-propane tricarboxylates described in British Patent No. 1,387,447 .
  • Polycarboxylates containing four carboxy groups include oxydisuccinates disclosed in British Patent No. 1,261,829 , 1,1,2,2-ethane tetracarboxylates, 1,1,3,3-propane tetracarboxylates and 1,1,2,3-propane tetracarboxylates.
  • Polycarboxylates containing sulfo substituents include the sulfosuccinate derivatives disclosed in British Patent Nos. 1,398,421 and 1,398,422 and in U.S. Patent No. 3,936,448 , and the sulfonated pyrolysed citrates described in British Patent No. 1,439,000 .
  • Aromatic polycarboxylates include mellitic acid, pyromellitic acid and the phthalic acid derivatives disclosed in British Patent No. 1,425,343 .
  • the preferred polycarboxylates are hydroxycarboxylates containing up to three carboxy groups per molecule, more particularly citrates.
  • Another optional detergent composition ingredient is a suds suppressor, exemplified by silicones, and silica-silicone mixtures.
  • Silicones can be generally represented by alkylated polysiloxane materials while silica is normally used in finely divided forms, exemplified by silica aerogels and xerogels and hydrophobic silicas of various types. These materials can be incorporated as particulates in which the suds suppressor is advantageously releasably incorporated in a water-soluble or water-dispersible, substantially non-surface-active detergent-impermeable carrier.
  • the suds suppressor can be dissolved or dispersed in a liquid carrier and applied by spraying on to one or more of the other components.
  • Levels of smectite clay are normally in the range from 5% to 15%, more preferably from 8% to 12% by weight, with the material being added as a dry mixed component to the remainder of the formulation.
  • Organic fabric softening agents such as the water-insoluble tertiary amines or dilong chain amide materials are incorporated at levels of from 0.5% to 5% by weight, normally from 1% to 3% by weight, whilst the high molecular weight polyethylene oxide materials and the water soluble cationic materials are added at levels of from 0.1% to 2%, normally from 0.15% to 1.5% by weight.
