Definitions

  • the present invention relates to the use of an ethoxylated aliphatic alcohol containing at least 25 ethylene oxide groups to improve dissolution and/or dispersion in the wash liquor of a particulate detergent composition.
  • the invention is of especial applicability to particulate detergent compositions, containing no, or low levels of, phosphate builder and to compositions of high bulk density.
  • Detergent powders typically comprise anionic and/or nonionic surfactants.
  • Nonionic surfactants are particularly effective in removing hydrophobic soils such as hydrocarbon oils, complex fats and other long-chain unsaturated and saturated glycerides.
  • the nonionic surfactant may form a viscous phase which may impede dissolution.
  • Nonionic surfactants having a low degree of ethoxylation, generally employed because of their oily soil detergency, are especially problematic in this respect.
  • the present invention provides the use set out in Claim 1.
  • the granular detergent composition has a bulk density from 600 to 1100 kg/m 3 , preferably from 700 to 1100 kg/m 3 .
  • Various postdosed ingredients such as sodium carbonate, bleach material and foam depressing agent, may be added to the composition as desired.
  • the composition may be prepared by spray-drying optionally followed by mixing or by dry-mixing/agglomeration. For obtaining high bulk densities, the composition is preferably prepared by dry-mixing/agglomeration.
  • the composition contains surfactant system, builder material and a dissolution aid. It is preferred that the dissolution aid is present in the composition of the invention as a separate granular component. Preferably the dissolution aid is substantially pure ethoxylated aliphatic alcohol containing at least 25 ethylene oxide groups.
  • the dissolution aid contains at least 50 ethylene oxide groups, more preferably at least 80 ethylene oxide groups.
  • the dissolution aid is suitably present at a level of from 0.01 to 1% by weight, preferably from 0.05 to 0.5% by weight based on the composition.
  • the surfactant system present in the detergent composition suitably contains alkoxylated nonionic surfactants having an average degree of alkoxylation of at most 11.

  • the proportion of nonionic surfactant having a branched aliphatic alcohol is in the range from 10 to 60% by weight for example about 55% by weight based on the total amount of nonionic surfactant in the composition.
  • Nonionic detergent-active compounds and the dissolution aid together are suitably present in the compositions in a total amount of from 2 to 50% by weight, preferably from 5 to 30% by weight.
