Publication number: 20230167601Abstract: A stable aqueous dispersion containing a mixture of an anionic polymer, quaternary ammonium salt, a dispersion agent and water. The dispersing agent is poly (acrylamide-co-acrylic acid) or copolymer of maleic acid and an olefin. The dispersion can be applied to textile materials and nonwoven substrates. Nonwoven substrates, such as polypropylene substrates can be treated with the dispersion to provide a highly active quick killing antimicrobial effect: Log 4 reduction in 5 minutes. This would be useful to deactivate the SARS-CoV-2 virus, which causes Covid-19.Type: ApplicationFiled: April 30, 2021Publication date: June 1, 2023Inventors: Ted W. DEISENROTH, Carmen A. HENDRICKS-GUY, Glen CUNKLE

Publication number: 20140030304Abstract: A process for the treatment of a synthetic textile (T) with a cationic biocide (B) and at least one anionic polymer (P) which comprises the step of treating the synthetic textile with an aqueous composition containing the cationic biocide (B) in a concentration (c1) and containing the anionic polymer (P) in a concentration (c2), wherein the concentrations (c1) and (c2) are selected so that the ratio (R) of negative charges of the anionic polymer (P) to the positive charges of the cationic biocide (B) is between 10:1 and 1:1, leads to textiles with long term biocide activity.Type: ApplicationFiled: July 11, 2013Publication date: January 30, 2014Applicant: BASF SEInventors: Sebastian Koltzenburg, Thomas Gottschalk, Volodymyr Boyko, Thomas Glen Cunkle, Carmen Hendricks-Guy

Publication number: 20110318280Abstract: Polymeric anti-microbial agents produced by substituting the nitrogen atoms in the backbone of ethylenimine polymers, for example, substitution with aralkyl groups, are provided. The agents are believed to have low human toxicity while being effective against a variety of pathogens and are useful in applications involving human contact, such as cosmetics, hair care products and textiles, as well as in applications with much less human contact, such as coatings.Type: ApplicationFiled: September 7, 2011Publication date: December 29, 2011Inventors: Xinyu Huang, Ted Deisenroth, Andrea Preuss, Sophie Marquais-Bienewald, Carmen Hendricks-Guy, John Jennings

Publication number: 20110250253Abstract: Highly active, leach-resistant, antimicrobial nonwoven textiles are prepared by treating at least one surface of the nonwoven material with an anionic polyelectrolyte, such as carboxymethyl cellulose, alginic acid, poly(acrylic acid) etc and at least one select quaternary ammonium antimicrobial agent. The textiles of the invention, and products produced from them, exhibit a highly effective quick kill rate, for example a log 4 CFU reduction within a 5 minute contact time, against microbes such as fungi and gram (?) and gram (+) bacteria.Type: ApplicationFiled: April 8, 2011Publication date: October 13, 2011Inventors: Glen T.

Publication number: 20090068138Abstract: Polyglycerol anti-microbial agents and compositions are provided. The agents are effective against a variety of pathogens including fungi, Gram positive bacteria and Gram negative bacteria yet are expected to have low human toxicity due in part to their polymeric nature. Applications for the polyglycerol anti-microbial agents and compositions include those involving human and plant contact, such as cosmetics, hair care products, textiles and plant protections, as well as in applications with much less human contact, such as plastics, coatings, wood, paper and other materials of construction.Type: ApplicationFiled: September 9, 2008Publication date: March 12, 2009Inventors: Xinyu Huang, Carmen Hendricks-Guy, Stewart Todd Elder, Andrea Preuss, Ted Deisenroth

Patent number: 7419513Abstract: Compounds which have a benzotriazole and a hindered amine moiety in the same molecule are typified by the formula A wherein at least one of G2, R1 or R2 contains a hindered amine moiety are extremely effective light stabilizers having both the UV absorbing activity of a benzotriazole and the light stabilizing efficacy of a hindered amine in the same molecule. These compounds are effective stabilizers for thermoset resin compositions, thermoplastic resin compositions, for photographic applications, for pigmented or dyed polypropylene, polyamide or polyester fibers, and for white, dyed, dipped, unscented and/or scented candle wax against discoloration and fading when incorporated therein alone or in combination with an antioxidant.Type: GrantFiled: September 13, 2004Date of Patent: September 2, 2008Assignee: Ciba Specialty Chemicals CorporationInventors: Mervin G. Wood, Jacqueline Lau, Ramanathan Ravichandran, Andrea R. Smith, Joseph Suhadolnik, Peter Solera, Joseph S. Puglisi, Carmen Hendricks-Guy, Stephen D. Pastor, Luther A. R. Hall
