The secret to BANDA-SiL® is a patented proprietary formula known as Ag21 Complex that bonds Silver and Chitosan. The positive charge of this unique complex attaches to negatively – charged human tissue like a magnet, creating a layer over wounds for a moist wound environment.

Why Silver?

Silver has a long history of use in human health care. From water purification and wound care to bone prostheses and reconstructive surgery, silver has proven to be effective against antibiotic-resistant germ strains, which is why silver is used as a preservative.

What is Chitosan?

Our Chitosan is a naturally occurring polymer found in mushrooms. Like silver, chitosan has a broad range of accepted uses in healthcare.

It is the chitosan component of Ag21 Complex that creates a cationic (positively-charged) biodegradable film that naturally bonds with anionic (negatively-charged) human skin. This natural bond results in a protective layer that gradually erodes as skin cells are shed during the healing process.
