| How does Saltidin® protect you?
Modern repellents contain an active ingredient, solvents and usually
a perfuming agent as well. Once the product has been applied, the
solvents evaporate, leaving the active ingredient on the skin. The
active ingredient evaporates slowly, forming a "scented" film on the
skin, and the repellent acts for as long as it takes for the active
ingredient to evaporate completely. The "scent" in the product disrupts
the mechanism that attracts mosquitoes, flies and ticks to human skin.
The resulting neuronal pattern seems to be what keeps insects away from
parts of the skin that have been treated with repellent.
In
chemical terms, most repellents belong to one of four groups: amides,
alcohols, esters or ethers. They are liquids or solids with a
relatively low melting point and a boiling point above 150 ºC. They
evaporate slowly at room temperature.
It is important to note
that, in contrast to insecticides, the purpose of repellents is not to
kill insects but to prevent them from biting. This means that
repellents have much better toxicological profiles than insecticides.
