Publication number: 20230277704Abstract: A disinfectant composition that contains a unique combination of a primary antiviral agent and a secondary antiviral agent is provided. More particularly, the primary antiviral agent includes a polyprotic acid having a low first acid dissociation constant and the secondary antiviral agent is selected from the group consisting of an anionic N-acyl compound, metal halide salt, amine compound, amine compound, aliphatic amine oxide, alkyl glycoside, alcohol ethoxylate, and combinations thereof. By selectively controlling the particular nature of each antiviral agent and their relative concentration, the present inventors have discovered that a synergistic affect can be achieved in which the disinfectant composition is capable of exhibiting an antiviral efficacy against non-enveloped viruses.Type: ApplicationFiled: April 28, 2023Publication date: September 7, 2023Inventors: Douglas R. Hoffman, Amy L. Vanden Heuvel, Jeremy D. Paulsen, Paige N. Anunson, Lisa M. Kroll, Corey T. Cunningham, David W. Koenig

Publication number: 20210092949Abstract: A disinfectant composition that is capable of inactivating non-enveloped viruses as well as other microorganisms, such as gram negative and gram positive bacteria, fungi, parasites, enveloped viruses, etc., is provided. Through selective control over the nature of the acid(s) employed and the overall pH level, the present inventors have discovered that the composition can achieve rapid antiviral efficacy, particularly against non-enveloped viruses. Once applied to a surface (e.g., hard surface), the disinfectant composition forms a film that remains capable of providing residual antiviral activity. Notably, the present inventors have discovered that the use of a vinylpyrrolidone copolymer in combination with a polyquaternary ammonium polymer and cationic surfactant can have a synergistic effect on the stability of the film such that it can also achieve long-term, residual antiviral activity.Type: ApplicationFiled: December 4, 2020Publication date: April 1, 2021Inventors: Amy L. Vanden Heuvel, Douglas R. Hoffman, Jeremy D. Paulsen, Rebecca Vongsa, Paige N. Anunson, Lisa M. Kroll, Corey T. Cunningham, David W. Koenig

Patent number: 7154018Abstract: An absorbent article for absorbing body waste. The includes a permeable liner having a body-facing surface oriented for facing a wearer when the absorbent article is worn and an absorbent-facing surface opposite the body-facing surface, an outer cover, and an absorbent body positioned between the liner and the cover. A Yucca sp. extract is positioned between the body-facing surface of the liner and the outer cover.Type: GrantFiled: December 20, 2001Date of Patent: December 26, 2006Assignee: Kimberly-Clark Worldwide, Inc.Inventors: David W. Koenig, Lisa M. Kroll

Patent number: 6610314Abstract: Antimicrobial formulations, which may be essentially free of an antimicrobial active, comprising one or more proton donating agents and an alkyl phosphate anionic surfactant comprising a mono alkyl phosphate having the chemical structure: wherein R1 is a saturated or unsaturated straight chain or branched alkyl group having from about 8 to about 22 carbon atoms, x is a number from 0 to about 20, and R2 and R3 are independently selected from hydrogen, an alkali metal, or an alkanol amine, are provided and described herein. The formulations may be incorporated into wet wipes or various other personal care items such as facial tissue, bathroom tissue or feminine care products, or may be incorporated into lotions or soaps which may be applied directly to the skin. The antimicrobial formulations of the present invention have been found to have surprisingly high activity against numerous bacteria and other microorganisms.Type: GrantFiled: March 12, 2001Date of Patent: August 26, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: David W. Koenig, Lisa M. Kroll, David R. Otts, Douglas B. Cole, Katherine D. Stahl
