Patents by Inventor Ronald A. Barnhart

Ronald A. Barnhart has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8372790
    Abstract: An antimicrobial hand wash includes a soap, an antimicrobial agent, and an amine salt. The amine salt is found to increase the antimicrobial efficacy of the hand wash. The amine salt produced through the reaction of monoethanolamine and lactic acid is of particular interest as a soap addition. In processes of this invention, it is possible to create the desired amine salt in the soap in situ.
    Type: Grant

  • Patent number: 8329758
    Abstract: This invention relates to an antimicrobial skin sanitizing composition for disinfecting skin, and particularly, hands. The composition contains at least 60 percent of an aliphatic alcohol having from 1 to 4 carbon atoms, from about 0.1 to about 5 weight percent of a thickening agent, and an effective amount of a GRAS or amino acid neutralizer to neutralize the thickening agent.

  • Publication number: 20100261630
    Abstract: An antimicrobial hand wash comprises an active ingredient and an amphoteric surfactant that is a derivative compound of a fatty amine with a nitrogen atom bound to at least one, but not greater than two, propionic acids. These specific amphoteric surfactants have unexpectedly been found to be compatible with active ingredients such that the antimicrobial efficacy is maintained, while foam quality is improved when the hand wash is dispensed as foam. Other antimicrobial hand washes include polyethylene glycol or polypropylene glycol derivatives that dissolve at least a portion of the active ingredient, thus reducing the amount of solids in the formulation, and making a cold manufacturing process possible.

  • Patent number: 7517842
    Abstract: An antimicrobial hand wash comprises an active ingredient and an amidoamine based cationic surfactant having a fatty chain with from 6 to 24 carbon atoms. These cationic surfactants are compatible with common active ingredients such that antimicrobial efficacy is maintained, while foam quality is improved when the hand wash is dispensed as foam. Other antimicrobial hand washes include specific amidoamine based cationic surfactants that dissolve at least a portion of the active ingredient, thus reducing the amount of solids in the formulation, and, in some instances, making a cold manufacturing process possible.
