Yes, it's normall for it to "evaporate" over time.

The reson is, glycol will leak out of the smallest path were plain water will not. Even a tiny. undetectable leak will make the coolant level go down over time.

However, the amount should be small and nothing should "dry up" over the course of say, a year.
