Technology inspired by natural laws

Cyclofresh® battles bad smells even before they develop. This is achieved through catching the body's secretions from the skin, such as sweat, which are responsible for the development of bodily odors within the textile.

The process is based on cyclodextrins, circular sugar molecules, derived from starch, that are built like little tumblers and can absorb what are known as 'guest'molecules. Making optimal use of this storage property, Cyclofresh® uses cyclodextrins for a dual purpose: to store fragrances to be released and to capture the organic molecules of sweat that cause unpleasant smells.

The mechanism is triggered by the moisture that develops when a person sweats. So if you wear a garment treated with Cyclofresh® and you sweat, the cyclodextrins become active as soon as they come into contact with the moisture. The resulting chemical reaction causes the trapped fragrances to be released and, at the same time, ensures the molecules in sweat responsible for unseemly odors in the textile are locked away.

The secret lies in the properties of the sugar molecules. From the outside they are surrounded by a hydrophilic edge, but the cavity on the inside is hydrophobic and does not bind to water.
