Anti-odour textile technology supplier Polygiene is set to present a new, 100% bio-based active ingredient in response to market demand for metal-free antimicrobial additives at sports industry exhibition ISPO Munich (November 28-30).

The technology, called StayFreshBio, offers a plant-based alternative and will complement the Swedish group’s existing, silver-based offer. Its active ingredient is derived from “a natural, organic acid that is widely used in the food, pharmaceutical and cosmetics industries.”
