Definitions

  • the bulk density of the of sodium tripolyphosphate particles is preferably 0.75 Kg/M 3 or less, more preferably from 0.52 to 0.72 Kg/M 3 .
  • the particles which contain or consist of sodium tripolyphosphate preferably have a small mean particle size, such as not over 300 ⁇ m, better not over 250 ⁇ m. Small particle size can if necessary be achieved by grinding.
  • anionic surfactants are listed in standard texts such as Surfactants in Consumer Products; Theory, Technology and Application, J. Falbe, ed. Springer-Verlag 1987 and Handbook of Surfactants, M.R. Porter, Blackie & Son, 1991.
  • Preferred anionic surfactants include the conventional Cll- C18 alkyl benzene sulfonates and primary, secondary and random alkyl sulfates, the C 8 -C 18 alkyl alkoxy sulfates and the C 8 -Ci 8 alpha-sulfonated fatty acid esters and the like.
  • Particularly preferred polymeric polycarboxylates are co- polymers derived from monomers of acrylic acid and maleic acid.
  • the average molecular weight of these polymers in the acid form preferably ranges from 4,000 to 70,000.
  • Another type of polymeric polycarboxylic compounds suitable for use in the composition of the invention are homo- polymeric polycarboxylic acid compounds with acrylic acid as the monomeric unit.
  • the average weight of such homo- polymers in the acid form preferably ranges from 1,000 to 100,000 particularly from 3,000 to 10,000.
