  • Patent number: 6310031
    Abstract: A method of inhibiting soil redeposition on fabric stained by one or more quaternary compounds by providing a sulfonated material in an effective amount to a wash liquor. The sulfonated material includes water-soluble sulfonated polymers. Generally, the sulfonated material is incorporated with a laundry detergent to provide a use level of about 30 ppm to about 300 ppm in the wash liquor.

  • Patent number: 5419847
    Abstract: The present invention provides an aqueous liquid bleach composition which remains stable over an extended period of time. The liquid bleach is easily pourable since it has a relatively low viscosity. The liquid bleach generally comprises (a) from about 1% to about 25% by weight of a water-soluble bleach activator; (b) from about 0.1% to about 10% by weight of hydrogen peroxide; (c) from about 1% to about 20% by weight of a phase stabilizer; (d) from about 0.001% to about 2% by weight of a chelating agent; and (e) the balance water. The liquid bleach composition is isotropic, translucent and has a viscosity of less than about 500 cps.

  • Patent number: 5409632
    Abstract: An aqueous cleaning and bleaching composition with a pH of from about 0.5 to about 6, which contains amidoperoxyacid, hydrogen peroxide, and acylated citrate ester which has been emulsified in two or more ethoxylated alcohols is described.

  • Patent number: 4514444
    Abstract: Fabric cleaning/conditioning compositions of improved stability are disclosed for use through-the-wash in conjunction with machine dryers. This is accomplished by incorporating a low level of polyethylene glycol into small, discrete amine salt nodules. These nodules pass virtually unchanged through the wash and rinse; become entangled in the fabrics when spun or wrung out; and then melt, spread, and condition the fabrics when heated in a dryer.
