Are all humectants sticky?

While using a topical lotion based on [ethanol](https://en.wikipedia.org/wiki/Ethanol), water and [propylene glycol](https://en.wikipedia.org/wiki/Propylene_glycol), I noticed that it becomes sticky while drying. Propylene glycol is a [humectant](https://en.wikipedia.org/wiki/Humectant) and is used for this purpose in pharmaceuticals and cosmetics. This made me wonder: Is stickiness a general property of *all* humectants?
