BioStatic Stays Fresh Technology


Polygiene BioStatic™ technology helps deliver sustainable fabrics as it saves water, energy and garments due to less need for washing. The treatment is based on a silver salt solution and provides protection against body odors and more.

Sweat, heat and humidity are nourishment for bacteria and they will grow and die in ever-increasing numbers. Absorbing, hiding or delaying will fail at some point. This antimicrobial and anti-odor treatment simply makes it impossible for them to multiply. The result – it stops the odor at the source to make your items stay fresh, and it works for the lifetime of the garment.

BioStatic stays fresh technology stops the growth of odor-causing bacteria and fungi in the material, which makes products stay fresh and hygienic. As several treatments can be simultaneously applied at the finishing stages of the fabric production process, no additional water or energy is needed and the impact on the environment is reduced.

What is Polygiene BioStatic technology and how does it work?
It is based on silver salt (silver chloride). Silver chloride is naturally present in water and soil. Its particles have a large number of silver ions per surface area. Due to the structure of the particles, very small amounts of silver salt are needed.

Polygiene is in most cases co-applied with other treatments to the fabric during the finishing stage. This helps minimize the impact on the environment because additional energy or water isn’t required.

Any effects when worn next to the skin?
Polygiene has a background in the healthcare sector and the treatments have undergone extensive skin sensitivity testing.
There is no interference with bacteria naturally occurring on the skin – it is active only on the material’s surface and does not interfere with bacteria naturally found on the skin, even when used for long periods of time. Tests also conclude that there is no identified risk from dermal and oral contact with silver treatments. Polygiene isn’t nanosilver.

The product is manufactured in the EU with minimal use of resources and in accordance with strict environmental regulations.

As several treatments can be simultaneously applied, no additional water or energy is needed and the impact on the environment is reduced.

Does it have any environmental approvals?
Polygiene BioStatic technology is approved by bluesign®, the textile industry’s demanding environmental certification, which uses life cycle assessment. The technology also has Oeko-Tex Eco Passport certification, is registered under the EU Biocidal Products Directive (BPD), and is approved by the US Environmental Protection Agency (EPA). It also meets the requirements of REACH, the EU’s chemicals legislation.

Can treated garments be recycled?
Polygiene treated garments and gear can be recycled.

How has the historical usage of silver impacted the environment?
Silver has been accruing in the environment since as far back as Roman times – when it was due to the increased usage of lead. Significantly higher silver levels then emerged after the Industrial Revolution. When you examine different layers of peat, you can see that the levels in one year’s layer suddenly increased 100-fold compared to Roman times. Since then, the levels have remained approximately the same. Any new silver added to the soil is so diluted that it’s quite a minor addition to the old levels. The silver levels today are higher than they were during Roman times, but it’s not a major problem. Plants, bacteria, worms and other organisms in the soil tolerate significantly higher levels than we currently have.

Combination of the
two stays fresh technologies

The combination of the Polygiene BioStatic™ and Polygiene OdorCrunch™ Stays Fresh technologies stops odors caused by bacteria, such as from sweat, as well as odors from environmental factors, such as cooking fumes. The result is the most efficient and comprehensive anti-odor solution. Garments and other products will feel fresh and clean despite sweaty conditions and smelly environments. And by making products last longer this combination reduces waste, creating more eco-friendly clothes and sustainable fabrics.
