  • All of the embodiments of the present dry-cleaning compositions contemplate polysulfonic acid as a critical component.
  • Polysulfonic acid is a polymer which is 17% active in water and has a high viscosity (more than about 20,000 cps) . It has been determined that polysulfonic acid affords special advantages when present in the dry-cleaning compositions described herein. For instance, polysulfonic acid acts as a surfactant and exhibits stain removal properties, adds slip characteristics to fabrics (e.g., reduction in drag), and helps dissolve/disperse the other components of the composition onto the fabric without leaving a white residue. Polysulfonic acid acts as a coupling agent to facilitate higher amounts of solvent into the system. Unlike the chlorinated hydrocarbon solvents used conventionally, in this invention polysulfonic acid functions with significant or even high amounts of water.
  • polysulfonic acid With polysulfonic acid, it is possible to include at least a low amounts of solids in the composition while retaining a relatively high viscosity, which allows for controlling the volatility of the active ingredients in the composition (for instance, allowing controlled release of the ingredients) . Further, the pH of the composition including polysulfonic acid may be adjusted without affecting viscosity. Thus, the pH can be appropriately adjusted as needed for particular textiles .
  • Polysulfonic acid is commercially available from, for example, Henkel under the name HSP-1180 or Rheothik 80-11.
  • Water is necessary as a carrier in this invention and to disperse the polysulfonic acid and build sufficient viscosity with it.
  • the presence of the water is also useful to enhance the cleaning and other beneficial properties of the polysulfonic acid and, if added, surfactants.
  • Another advantage of the presence of water is that it helps suppress the flash point of the organic solvent, if added, and therefore makes the dry- cleaning systems safer for general use.
  • the dry-cleaning compositions may further include organic solvents.
  • the organic solvent should be water-miscible, or at least partially water-miscible. As would be understood by someone skilled in this art, the less water that is present in the composition, the lower the polarity of the organic solvent is preferred.
  • the major portion of the organic solvent can be a glycol ether.
  • glycol ethers are lower (alkoxy) - or lower (alkoxy) lower (alkoxy) -ethers of ethanol or isopropanol .
  • preferred glycol ethers are available under the trade names Arcosolv ® (Arco Chemical Co.) or Cellosolve ® , Carbitol ® , or Propasol ® (Union Carbide Corp.), and include, e.g., butylCarbitol ® , hexylCarbitol ® , methylCarbitol ® , and Carbitol ® itself, (2- (2 -ethoxy) ethoxy) ethanol .
  • the more preferred organic solvents include dipropylene glycol n-propyl ether, dipropylene glycol n-butyl ether, tripropylene glycol methyl ether, 3 -methoxy-3 -methyl -1-butanol and ⁇ -butyrolactone . Certain of these solvents, including 3 -methoxy-3 -methyl-1-butanol and ⁇ - butyrolactone, are preferably used in combination with at least one other solvent. When ⁇ - butyrolactone is the solvent used it is preferably used in small amounts and mixed with another organic solvent .

  • glycol ethers are commercially available, for instance, from Dow, Union Carbide and Arco. Of course, the choice of glycol ether can be readily made by one of ordinary skill in the art on the basis of its volatility, wt-% of the total dispersion and the like.
  • Other useful organic solvents include lactones, for instance, dimethyl isosorbide (made by ICI, under the name of Arlasolve DMI) .
  • solvents are probably not useful because these solvents can dissolve or stain 100% acetate fabrics.
  • solvents include N-methyl-2-pyrrolidone, ⁇ butralactone, methoxytriglycol , and propylene carbonate .
