  • Patent number: 6849585
    Abstract: The invention relates to soap/free fatty acid bars in which high amounts of free fatty acid (i.e., greater than 35%, preferably greater than 40% and ratio of FFA to soap greater than 1:1) and low levels of synthetic may be used. In the bar, the free fatty acid is believed to form a complex which is believed to act as a structurant, thereby allowing less use of synthetic surfactant. The bar should require less synthetic surfactant. Total amount of unsaturated material in soap and fatty acid should be no higher than 15% In a second embodiment of the invention, the bar may be made by a neutralization process whereby fatty acid is combined with caustic (e.g., lower than 50% caustic) to form soap and free fatty acid in defined amounts or proportions.

  • Patent number: 6849587
    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.

  • Patent number: 6846786
    Abstract: The present composition comprises bars having small amounts of surfactant and high amounts of sugars which bar maintains good rates of wear and foams adequately. The sugar has unexpectedly been found to structure bars, even when little or no insoluble fatty acid is used, without degrading bar properties. Further, the invention comprises a process for making such bars which are white and consumer desirable.

  • Patent number: 6837405
    Abstract: A dispensing container is provided which includes an ovaloid bottle and an ovaloid overcap. The bottle includes a dispensing aperture. The overcap is formed with a roof at a closed end thereof and a surrounding wall with a mouth defining an open end opposite the closed end. A pintel and a circular collar both project from the roof in a direction toward the open end. The pintel is sealingly fittable into the dispensing aperture. The circular collar ensures that the pintel will not misalign with the aperture of the bottle and thereby avoids damage to the soft plastic of the pintel. The bottle has a shoulder which serves as a camming device for easy removal of the overcap in a twist motion.
