AgPOLYMER® is the last advanced generation of Cheese Coating (cheese protective covering), whose active principle is the silver ion zeolite (no nanoparticles) incorporated into the polymer. (Patent EU 1922936)

Antimicrobials are natural or synthetic, organic or inorganic substances, inhibiting the growth of bacteria and/or spore fungi. The antimicrobial effectiveness depends on different parameters such as substrate concentration, temperature, pH, substrate typology, type of bacteria “to be fought”, besides moisture and oxygen.
Antimicrobials are used to keep the cheese surface clean, they destroy bacteria and/or spore fungi, in general they protect from pathogenic bacteria such as listeria (dangerous for humans), which is present in some cheese rinds.

A first great subdivision may be done between organic and inorganic bactericides as those based on Silver Ions. Silver has been recognized for its antimicrobial properties for a long time.

Silver ions are absorbed by bacterial charges, which destroy the cell walls, inhibiting the reproduction and stopping their metabolism.
Silver ions destroy the microorganisms immediately, stopping their enzymatic respiratory system (that is the energy production) and modifying the microbial DNA and the cell wall.
They do not have toxic effects on human cells in vivo.

In medicine the use of silver ions as antimicrobic/anti-inflammatory to treat burns and baby eye infection has been a consolidated practice for a long time.

Silver is also used in the aerospace field; actually NASA uses silver to preserve the water naturalness in the Space Shuttle.
