  • Publication number: 20220289908
    Abstract: The presently disclosed and/or claimed inventive concept(s) relates to a method for preparing a reaction product, comprising (1) molten mixing a first active hydrogen containing component and a first alkali hydroxide to form a first mixture; (2) adding water into the first mixture to dissolve the first molten alkali hydroxide to form a second mixture; (3) reacting a first hydrophobic component with the second mixture to provide a Diluent; (4) molten mixing at least one second active hydrogen containing component, a second alkali hydroxide and the Diluent to form a third mixture; (5) adding water into the third mixture to dissolve the second molten alkali hydroxide to form a fourth mixture; and (6) reacting the fourth mixture with a gem-polyhalide compound or a sulfonate ester for a sufficient time to form the reaction product.

  • Patent number: 10303842
    Abstract: A product testing assembly is described. The product testing assembly may include a substrate, at least one measuring device, and at least one data processing system. The substrate has at least one surface configured to receive an application of a product to be tested. The at least one measuring device is configured to sense measured quantities as product is applied to the substrate and output one or more signals representative of a sequence of forces and/or moments being applied to the surface of the substrate by the application of the product to be tested. The at least one data processing system has one or more processors configured to receive the one or more signals representative of the sequence of forces and/or moments being applied to the surface of the substrate, and to convert the one or more signals into an output signal representative of one or more application performance characteristics of the product to be tested.

  • Patent number: 10058498
    Abstract: The presently disclosed and/or claimed inventive concept(s) relates generally to the use of nonionic hydrophobically modified polysaccharides in personal care and household care compositions. More specifically, but not by way of limitation, the presently disclosed and/or claimed inventive concept(s) relates to the use of hydrophobically-modified cellulose ethers, such as hydrophobically-modified hydroxyethylcellulose (HMHEC) polymers in personal care and household care compositions. These compositions show pronounced syneresis in aqueous solutions or in the presence of surfactants, including nonionic surfactants and anionic surfactants such as lauryl sulfate (LS) and lauryl ether sulfate (LES). It is also contemplated that the surfactants used in the compositions be sulfate free and/or multi-tailed.
