Antimicrobials / Biostabilisers

Background

Antimicrobials are used to control the build up of bacteria, fungi and Algae on the surface of plastic products and textiles. They can be added to formulations in the same way as other ingredients, by use of Masterbatch, Compound or topical treatments.

Action

Organics typically burst the cell wall to inhibit growth but this action has resulted in the removal from sensitive applications because of fears related to mutation capabilities. Biomaster in contrast works in 3 subtle ways to reduce the bacteria safely and so alay all fear of mutagenicity;

1.	Silver ions may bind non-specifically to cell surfaces, causing some disruption to the cellular membrane function and allowing the silver ions to penetrate the microbe structure.
2.	Silver ions are highly reactive and readily bind to electron donor groups, with prime targets being the thiol groups (-SH) which are commonly found in enzymes within the microbe. This causes the enzymes to be denatured thus effectively incapacitating the energy source of the cell. As a result the cell cannot maintain osmotic pressure, vital substances leak out of the cell and the microbe will quickly die.
3.	Silver ions react with the base pairs of DNA thus preventing DNA replication.

Common Uses

MRSA

Biomaster is used across many industries particularly in the medical sector where it is supplied to 80 UK hospitals in a range of products from floor tiles, beds, bed linen, curtains, door handles to wall coverings & ceiling tiles.

Biomaster has a 99.9% protection against gram positive & gram negative bacteria and is particularly effective in reducing MRSA.

MRSA is a strain of Staphylococcus Auerus and is resistant to methicillin and most standard first line antibiotics.

The “Superbug” lies dormant on 30% of the population in areas such as the nose, and is often deadly when allowed to invade the skin, this is more likely to happen when a wound or graze is exposed. It is known to have more deteriorating affects on vulnerable people like the elderly and children, due to their weak immune systems.

In most cases MRSA bacteria generates infections on the skin in the form of boils, abscesses, Impetigo etc… The more distressing cases enter the bloodstream causing poisoning, failures to organs and even death.
