Anti microbial system

The table 1 summarises the challenge test data using Myavert C 5 part enzyme based preservation in a face mask 1 including speed of kill test to justify positive marketing claims for the anti-microbial system used in the product. Table 2 uses conventional chemical anti-microbials for a foot product at much higher levels than would be allowed for face application yet the speed of kill of the enzyme system is superior yet much more mild. 

Wells Plastics Ltd. of the UK, a compounder of additive masteibatches, has developed a technology that encapsulates silver ion anti-microbial systems within a soluble matrix. The silver ion formulations can help reduce infection in wound dressings, urinary catheters, and other medical applications. This article provides details.

Epidemiological studies and intervention trials with food and beverages rich in flavonoids are not conclusive although flavonoids were recognized to display numerous antioxidant, anti-inflammatory, anti-tumoral, and anti-microbial activities. The antioxidant capacity of flavonoids has been largely reported in numerous in vitro and ex vivo systems. Numerous reviews "" have been published on the antioxidant properties of flavonoids. Degenerative diseases are largely associated with oxidative mechanisms that may be counteracted by flavonoids. 

Utilising the usual levels of anti-microbials for cleansing products with normal user instructions of three minutes or longer contact time can achieve positive claims of anti-bacterial for Myavert C based enzyme preservation system without the stinging associated with alcohol. Table 1 gives the plate kill speed data for a face masque where the preservative also becomes a positive attribute. 

The systemic use of chloramphenicol is reserved only for life-threatening infections where other anti-microbial therapy has failed or is inadequate, since chloramphenicol may cause reversible aplastic anaemia as a side-effect. 

There are striking similarities between the anaesthetic effect discussed above and anti-microbial effects. Thus gases tiiat are general anaesthetics, even die inert noble gases, exhibit an anti-microbial effect. Furthermore this is correlated to the anaesthetic potency [57]. Moreover, it is possible to reverse this effect by hydrostatic pressiue. As discussed above there is an opposing effect of temperature on lipid phase transitions as compared to that of pressure, and this is also reflected in living systems. At 1,000 bar for example certain orgaiusms can survive at 104 C [57]. 

Results are presented of studies of three products for healthcare applications which include anti-microbial finishes or additives in the product. These products are upholstery fabrics coated with a clear coating that includes an anti-microbial additive, a fluid barrier system that involves a 2 mil film laminated to the back of an upholstery fabric that incorporates an anti-microbial additive in its adhesive system, and wallcoverings that include an anti-microbial additive in the back-coating. 

ATL Security Label Systems was established in 2007 to provide an advanced new line of labels, offering security and anti-counterfeiting features such as invisible digital forensic marking, track and trace, mass serialization, custom codes, 2-D barcodes, color shifting authentication, covert machine readable markers, and anti-microbial labels and packaging.
