The patented technology uses natural hollow particles to encapsulate both individual and combinations of terpenes. In the presence of moisture the natural particles swell, slowly releasing their terpene payloads. The moisture can originate from rainfall, dew, mist, sweat or natural skin moisture. When the moisture dries up the particles shrink and hold onto their payloads until moisture starts the cycle again. Moisture is a key ingredient in microorganism growth. The same moisture needed by microorganisms to grow causes the antimicrobial terpenes to be released, killing the bacteria, mold and fungi . Effectively, the product works when and where it is needed!
