Embodiment 1

[0066] Embodiment 1: minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)

[0067] program

[0068] Pure cultures of single microorganisms are grown in appropriate broths. Cultures were normalized to have a concentration very close to one million cells / ml using standard microbiological techniques. The microbial cultures are also standardized, the more reproducible the test results. Dilute the antimicrobial reagent multiple times (1:1) with sterile diluent. Following dilution of the antimicrobial agent, a volume of standardized inoculum corresponding to the volume of the diluted antimicrobial agent was added to each dilution vessel to achieve a microbial concentration of approximately 500,000 cells / ml. The inoculated serial dilutions of the antimicrobial agent are incubated at an appropriate temperature for a predetermined time (typically 18 hours) for the organism under test. Following incubation, the serially diluted vessels are observed f...

Embodiment 2

[0080] Example 2: Time kill test

[0081] program

[0082] All timed kill tests were performed using standard viable count procedures. Reference NB X34689. The following neutralizing solutions were used in all kill tests.

[0083]

[0084]

[0085] Fundamental

[0086] The timed kill test evaluates the amount of time required to kill a predetermined population of microorganisms. A wide variety of microorganisms are killed by Citrox BC actives. An important first step in characterizing such actives for antimicrobial towels is to identify the kill requirements. Efficacy claims are based on the number of bacteria killed within a predetermined time frame. The most stringent requirements are those established for food contact, where the active must achieve a 5-log reduction of the challenge organism within 30 seconds.

Embodiment 3

[0101] Example 3: Surface testing using paper towels impregnated with Citrox BC active

[0102] 1) Procedure: Add Citrox BC to paper towels

[0103] ("Bounty" is a registered trademark of Procter & Gamble) brand paper towels were used to make dry antimicrobial towels. The tissue is a conventional commercially available tissue product. Dilute Citrox BC Active Concentrate to desired concentration. Submerge a paper towel completely in the diluted active and wring it out by hand. Let the paper towels dry overnight.

[0104] 2) Procedure: Weight of Citrox BC active dry on brand paper towels

[0105] Will Brand paper towels were dried in an oven at 54°C to constant weight. exist Various dilutions of Citrox BC active were dried on paper towels, as described above. The paper towels were dried overnight at room temperature. The treated tissue was then dried to constant weight at 54°C. The difference in weight between the untreated tissue and the treated tissue is...

Abstract

Cellulosic fibrous materials are described which are impregnated with a bioflavonoid composition, the bioflavonoid content of the composition comprising at least naringin and neohesperidin. The use of such impregnated materials is also described, for example as paper or bamboo towels and cardboard, as well as the process for impregnating the materials.

Description

technical field [0001] The present invention relates to bioflavonoid-impregnated cellulose fiber materials, methods for impregnating said materials and their use. In particular, the invention relates to bioflavonoid-impregnated cellulosic fiber materials such as paper, tissue, bamboo fibers and paperboard and articles formed from these materials. Background technique [0002] Cellulosic fiber materials such as paper are used in a wide variety of different applications, from furniture applications to commercial applications, for example, in hospitals, schools, kitchens and laboratories, for example in paper towels, face masks, and even clothing such as bamboo fibers Application in the form of a sock. [0003] Some materials would benefit from having antimicrobial properties. These materials include, for example, cardboard, paper, cleaning wipes, tissues or face masks or even clothing. [0004] GB2468836 discloses compositions comprising bioflavonoid compounds and their ant...
