Patent number: 10888092Abstract: A composition and method are used to treat articles suspected of contamination with bacterial spores. The composition and method are effective against bacterial spores selected from C. diff., C. botulinum, C. sporogenes, B. cereus, and B. subtilis. The article can be a textile or a hard surface. The method includes preparing a first use solution by mixing ether amine in water and a second use solution by mixing percarboxylic acid in water; applying the first use solution to the article; and applying the second use solution to the article. An alternative method includes preparing a mixture of ether amine, percarboxylic acid, and water, and applying the mixture to the article.Type: GrantFiled: March 18, 2019Date of Patent: January 12, 2021Assignee: Ecolab USA Inc.Inventors: Jonathan Fast, Robert D.

Patent number: 10533147Abstract: Applicants have developed a physically and chemically stable solid composition containing a soil release polymer and an acidulant. The sour step thus accomplishes both stain removal and residual alkalinity removal. A novel method of using a soil release polymer and an acidulant together in the same post wash step of a laundry wash process is also disclosed. The solid composition is physically stable, even during aqueous dispensing, i.e. non-slumping and non-weeping. The solid could be formed through a melt, cast, or pressed process.Type: GrantFiled: May 9, 2014Date of Patent: January 14, 2020Assignee: Ecolab USA Inc.Inventors: Steven Lundberg, Jonathan P.

Patent number: 8246906Abstract: A method for antimicrobial treatment (e.g. antimicrobial treatment of food packaging and equipment) comprising applying to microbes a composition containing a diluting solvent (e.g., water), an antimicrobially-active solvent having a density different from the density of the diluting solvent, and an optional cosolvent, surfactant, or additional antimicrobial agent, wherein the amount of antimicrobially-active solvent or additional antimicrobial agent is sufficiently high and the amount of cosolvent or surfactant is sufficiently low so that the composition will provide greater than a 1-log order reduction in the population of bacteria or spores of Bacillus cereus within 10 seconds at 60° C. Preferred methods of the invention employ compositions containing an additional antimicrobial agent such as peroxyacetic acid.
