MATERIAL CONTROLLINGLY RELEASING A LIQUID ACTIVE SUBSTANCE BY EVAPORATION AND A MOSQUITO REPELLENT BRACELET COMPRISING SAID MATERIAL

摘要

A material controllingly releases by evaporation a liquid active substance and comprises a polymer material matrix impregnated with a liquid composition. The liquid composition contains a mixture of the active substance and a solute which reduces the active substance evaporation kinetics by decreasing a vapor pressure. A method for producing the material and an accessory comprising an element made therefrom are also described.
