  • Patent number: 10589134
    Abstract: The present disclosure is directed to a system and methods for maintaining or improving hand health and hygiene. More particularly, the system and methods prevent or overcome skin damage caused by frequent hand washing and use of hand sanitizers and/or cleansers. The hand care system comprises an article, such as an elastomeric glove, that has a moisturizing liquid liner composition on the skin-contacting surface of the article that delivers a skin health benefit to the skin, a non-irritating hand cleanser capable of moisturizing the skin, and a moisturizing hand sanitizer.

  • Patent number: 9648875
    Abstract: Formulations and wipes for imparting a sporicide to a surface are disclosed herein. To achieve the sporicidal efficacy of the product, a synergistic amount of an amine oxide surfactant and a mixture of oxidants is incorporated into the formulation. The operative sporicidal formulation contains a solvent, an amine oxide surfactant, a water soluble oxidant and a water insoluble oxidant. Typically, the formulation can contain about 0.05 to about 3.7 percent (by weight of the formulation) of an amine oxide surfactant, about 0.5 to about 4 percent (by weight of the formulation) of a water soluble oxidant, and about 0.1 to about 6 percent (by weight of the formulation) of a water insoluble oxidant.

  • Publication number: 20150064227
    Abstract: Formulations and wipes for imparting a sporicide to a surface are disclosed herein. Unexpectedly, a set of naturally derived ingredients have been found to combat and treat spore-based bacteria without the use of harsh chemicals. To achieve the sporicidal efficacy of the product, botanical extracts and/or botanical-derived ingredients have been incorporated into a sporicidal formulation. Example botanical extracts that demonstrated sporicidal activity include: Garcinia morella, Setaria italica, Salvia miltiorrhiza, and Psoralea corylifolia. An example botanical-derived ingredient that demonstrated sporicidal activity included gambogic acid. Unexpectedly, use of these botanicals and/or botanical-derived ingredients on skin provided a sporicidal benefit. Other botanicals and/or botanical extracts were not found to have sporicidal efficacy.

  • Patent number: 8551517
    Abstract: The present disclosure comprises a polymeric substrate that provides multiple releases of active agents. A substrate for multiple phase delivery of active agents is provided having a first polymer matrix layer having a first active agent disposed therein, a second polymer matrix layer having a second active agent disposed therein, and a coacervate layer disposed between the first polymer matrix layer and the second polymer matrix layer. Selected first and second active agents are included in the first and second polymer matrices such that as the first and second polymer matrices dissolve, the active agents are released. Multiple phase active agent release is achieved by constructing multiple layers of a polymer matrix containing an active agents formed with polymers having different solubility characteristics or with active agents at different concentration levels.

  • Patent number: 8318654
    Abstract: A cleansing composition is described. The cleansing composition generally contains an antimicrobial agent, a heating agent, and a thermochromic agent. During use, the heating agent heats the composition so that the antimicrobial agent becomes more effective. The thermochromic agent, on the other hand, changes the color of the composition as it is heated in order to indicate to a user that the composition is at a desired temperature. In an alternative embodiment, instead of containing a heating agent, a heating source can be used to heat the composition. The heating source can be, for instance, an electrical resistance heater.
