Sawyer® Controlled Release formula uses a patented Sub Micron Encapsulation process by which DEET is captured inside a Micale protein. Each microscopic particle of protein contains chambers which hold the DEET. Over a period of up to 24 hours your skin slowly dissolves the protein particles. As the particles are dissolved, DEET is released from the chambers for evaporation (the function which keeps the bugs away). At any point in time you may simply wash the remaining formula off your skin with soap and water.
- Almost no need to reapply later in the day
- Controlled release means less irratation for your skin and a lower possibility of direct skin absorbtion of deet
