Definitions

  • molecular weight and “Mw” are used interchangeably to refer to the weight average molecular weight as measured in a conventional manner with gel permeation chromatography (GPC) and conventional standards, such as polyethylene glycol standards.
  • GPC techniques are discussed in detail in Modem Size Exclusion Chromatography, W. W. Yau, J. J. Kirkland, D. D. Bly; Wiley-lnterscience, 1979 , and in A Guide to Materials Characterization and Chemical Analysis, J. P. Sibilia; VCH, 1988, p.81-84 . Molecular weights are reported herein in units of Daltons.
  • the automatic dishwashing composition of the present invention comprises: 0.5 to 15 wt% (preferably, 0.5 to 10 wt%; more preferably, 1 to 8 wt%; most preferably, 2.5 to 7.5 wt%) of a dispersant polymer blend, comprising: an acrylic acid homopolymer; and a copolymer of acrylic acid and a sulfonated monomer; wherein the dispersant polymer blend has a blend ratio of the acrylic acid homopolymer to the copolymer of 3:1 to 1:3 (preferably, 2.5:1 to 1:2.5; more preferably, 2:1 to 1:2; most preferably, 1.5:1 to 1:1.5), based on weight; 0.5 to 15 wt% (preferably, 0.5 to 10 wt%; more preferably, 1 to 8 wt%; most preferably, 2.5 to 7.5 wt%) of a surfactant (preferably, wherein the surfactant is a non-ionic surfactant); 1 to 75 wt% of a builder; and
  • the acrylic acid homopolymer used in the automatic dishwashing composition of the present invention has a weight average molecular weight, Mw, of 1,000 to 40,000 (preferably, 1,000 to 20,000; more preferably, 1,000 to 10,000; still more preferably, 1,000 to 5,000; most preferably, 2,000 to 4,000) Daltons.
  • Mw weight average molecular weight
  • Polymers included in the dispersant polymer blend used in the automatic dishwashing composition of the present invention are commercially available from various sources, and/or they may be prepared using literature techniques.
  • low-molecular weight polymers included in the dispersant polymer blend may be prepared by free-radical polymerization.
  • a preferred method for preparing these polymers is by homogeneous polymerization in a solvent.
  • the solvent may be water or an alcoholic solvent such as 2-propanol or 1,2-propanediol.
  • the free-radical polymerization is initiated by the decomposition of precursor compounds such as alkali persulfates or organic peracids and peresters.
  • the builder used in the automatic dishwashing composition of the present invention comprises one or more carbonates, citrates and silicates.
  • the builder used in the automatic dishwashing composition of the present invention includes a carbonate. More preferably, the builder used in the automatic dishwashing composition of the present invention includes a mixture of carbonates.
  • the automatic dishwashing composition preferably, comprises 10 to 75 wt% (preferably, 15 to 70 wt%; more preferably, 25 to 60 wt%; most preferably 30 to 50 wt%) of the carbonate(s).
  • the automatic dishwashing composition of the present invention optionally further comprises: a bleaching agent.
  • a preferred bleaching agent is sodium percarbonate.
  • the amount of the bleaching agent in the automatic dishwashing composition of the present invention, when present, is preferably at a concentration of 1 to 25 wt% (more preferably, 1 to 10 wt%, based on the dry weight of the automatic dishwashing composition.
