  • Patent number: 6797685
    Abstract: An aqueous liquid laundry detergent composition comprising a detergent surfactant (including anionic), an emulsifier with an HLB value below about 8.5; an oil; and an electrolyte in an amount to provide ionic strength indicator of from about 0.55 to about 6.7. The composition separates, upon standing for at most 24 hours at ambient temperature, into at least two layers, one of which is an emulsion with a continuous aqueous phase. The second layer is preferably a transparent composition.

  • Patent number: 6794348
    Abstract: A sher-thinnig lamellar gel detergent composition, employing non-neutralized fatty acid in a specific amount, depending on the total surfactant level. The weight % ratio of non-neutralized fatty acid to the total surfactant within a specific range, defined by the Gelling Index equation, results in gels with the desired properties. The inventive product offers an advantage of laundry pre-treater and a detergent in a single product.

  • Patent number: 6794347
    Abstract: According to the inventive method of making gels, the main mixture comprising most of the ingredients with the exception of a non-neutralized fatty acid or sulphonic acid, and/or other anionic surfactant acids is mixed, using at least one in-line static mixer, with the gelling post-mix comprising the non-neutralized fatty acid or sulphonic acid, or other anionic surfactant acids. The preferred process includes the mixing of the main mixture and the gelling post-mix just prior to either filling or storing the composition.

  • Publication number: 20040121931
    Abstract: Aqueous compositions comprising a perborate salt and a polyol. The advantageous properties of the composition include increased solubility of the perborate salt, increased available oxygen stability in an aqueous environment, and the capacity to increase the pH upon the dilution. The compositions are useful for bleaching various surfaces, especially in laundry cleaning.

  • Publication number: 20040058834
    Abstract: Liquid and/or gel laundry detergent compositions which snap back at the end of dispensing, thus eliminating or minimizing the dripping from the container. Employing a non-neutralized fatty acid to the total surfactant weight % ratio within a specific range, defined by the Snap Index equation, results in liquids and/or gels with the desired snap-back property.

  • Publication number: 20040058840
    Abstract: Gel detergent compositions which pile-up on a surface, upon dispensing, to minimize the spreading of the gel to a substantially larger area. The gels that can pile up are less messy to use and provide better stain removal, since more detergent is concentrated on the desired area of fabric (e.g., the spot). The composition comprises from about 10% to about 35% of a surfactant, from about 0.1 to about 5% of a non-neutralized fatty acid; from about 50 to about 85% of water; with the total of anionic surfactants selected from soap, linear alkyl benzene sulfonic acid, primary and secondary alkyl sulfates being more than 50% of total surfactant level.
