Hydrosol can also be referred to as floral water.

A hydrosol is an aromatic water that remains after plant material is steam distilled to create an essential oil. Hydrosol is a therapeutic water that retains many of the same properties as the essential oil but is very gentle and can be used pure on the skin.

Can be used for many uses including (but not limited to): all-purpose household cleaner, linen spray or room refresher, etc.
