  • Patent number: 10947482
    Abstract: A structured detergent composition has a yield stress point and includes a surfactant component present in an amount of from about 5 to about 50 weight percent actives, water present in a total amount of from about 40 to about 90 weight percent, and a smectite clay present in an amount of from about 0.2 to about 3 weight percent actives, each based on a total weight of the composition. The composition is formed by combining water and a smectite clay to form a mixture, applying shear to the mixture, combining the sheared mixture with an acidic surfactant, adding an acid to the combination of the sheared mixture and the acidic surfactant, then adding a base and a buffer. The method also includes the step of adding additional surfactants, wherein the combination of the acidic surfactant and the additional surfactants make up the surfactant component.

  • Patent number: 9222059
    Abstract: The present invention provides liquid cleaning compositions useful in cold water and hard water laundry applications, and methods for making and using such compositions. The compositions of the invention use surfactants or surfactant blends, such as ?-sulfofatty acid esters or mixtures thereof (optionally along with one or more additional components), that have increased solubility/stability at cold temperatures, at higher-than-usual concentrations, and/or in hard water, with the composition remaining as a clear liquid. In certain embodiments, the compositions of the invention may be provided in the form of a unit dose, for example in a water-soluble pack or pouch. In use, the compositions of the invention result in an enhanced detergency along with a reduced amount of residue remaining in the machine, on laundered garments or cleaned dishware or hard surfaces, and on the body in personal care settings, and demonstrate a longer shelf-life, particularly when stored or used in colder temperatures.
