  • Patent number: 7037883
    Abstract: A process of making a liquid laundry detergent composition comprising a polyanionic ammonium surfactant, the process comprising: forming the polyanionic ammonium surfactant by mixing a liquid carrier with: (a1) from about 0.03% to about 85%, by weight of the composition, of a conjugate acid of an anionic surfactant; and (a2) from about 10% to about 50%, based on the molar equivalent of the amount of the conjugate acid, of a polyamine; (a3) wherein the mixing of (a1) and (a2) is carried out in the substantial absence of bases other than the polyamine. Also included is a process wherein the monoanionic surfactant is formed along with the polyanionic ammonium surfactant, in which case a base other than the polyamine may be present but than the amount of such base should be no greater than the required stoichiometric amount of the base to form the monoanionic surfactant.

  • Patent number: 6972278
    Abstract: A shear-thinning lamellar gel detergent composition containing suspended particles, employing a non-neutralized fatty acid as a structuring agent, 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 and also provides a visual cue of suspended particles.

  • Patent number: 6815409
    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.
