Active only on the fabric surface, Polygiene does not interfere with perspiration or with the skin’s natural bacterial flora. Clothing and other textile-based, Polygiene-treated products are safe to use next to the skin. Polygiene particles are more than 100 times larger than nanoparticles and therefore are too large to penetrate to the skin’s barrier. Polygiene-treated fabrics have received Medical Class 1 approval in Europe, the same class that includes bandages for direct contact with open wounds. Polygiene-treated Airinum fabrics are bluesign® approved—meaning they offer the highest level of consumer safety by employing methods and materials in their manufacture that conserve resources and minimize impacts on people and the environment. These fabrics meet the bluesign criteria for textile chemicals and processes, including specific scrutiny for anti-microbial products.
