Evaporation of glycerol-water solutions?

At high concentrations of glycerol (90% volume for example), a glycerol-water solution tends to "suck" water vapor from atmosphere.
At low concentrations, the water evaporates.
Do you know what is the limit concentration between these two behaviours ? Or how to calculate it ?
Thanks

Glycerol and water do not mix well on their own. (Oil and water) To force them into one solution, try throwing in some water soluble alcohol, e.g. Methanol, Ethanol, Isopropanol etc.
