  • Patent number: 4397777
    Abstract: This invention relates to heavy duty laundry detergent compositions comprising a water-soluble mixture of paraffin sulfonate detergent, olefin sulfonate detergent and sodium silicate plus a water-insoluble molecular sieve or colloidal silica.
    Type: Grant
    Filed: July 18, 1980
    Date of Patent: August 9, 1983
    Assignee: Colgate Palmolive Company
    Inventor: Joseph A. Yurko
  • Patent number: 4064062
    Abstract: A stabilized activated percompound bleaching composition comprises a mechanical mixture of a bleaching percompound, such as sodium perborate tetrahydrate, an activator for such percompound, such as 2-[bis(2-hydroxyethyl)amino]-4,6-dichloro-s-triazine, a molecular sieve zeolite, such as an anhydrous type 4A synthetic molecular sieve zeolite and a higher fatty acid, such as myristic acid. The bleaching composition is made by mechanically mixing the various powdered constituents, preferably by tumbling at about room temperature, and the product resulting is more stable on storage and more effective as a bleach in removing various stains from laundry than are similar products which do not contain the higher fatty acid.Also within the invention is a stabilized activated percompound bleaching detergent composition, including the described bleaching composition plus a synthetic organic detergent, such as sodium higher linear alkylbenzene sulfonate.

  • Patent number: 4009114
    Abstract: A non-phosphate anionic detergent composition comprising an anionic sulfonate detergent, at least one soap, about 5 to 35% of a water-soluble salt mixture of alkali metal silicates, and alkali metal carbonates. These laundry products are suitable for use in cold water (e.g., 70.degree.Fahrenheit).
    Type: Grant
    Filed: October 3, 1975

    Inventor: Joseph A. Yurko
  • Patent number: 3959165
    Abstract: A biodegradable, non-polluting heavy duty synthetic organic detergent composition which washes laundry well, leaves it feeling softer than laundry washed with other commercially available and successful non-polluting products and is suitable for use at low temperatures without causing yellowing of the white articles of laundry washed includes higher paraffin sulfonate, ethoxylated alcohol nonionic detergent, soap, alkali metal silicate, alkali metal carbonate (which may be accompanied by bicarbonate), sodium carboxymethyl cellulose and moisture, preferably in spray dried, free flowing bead form.
