Hydrosols are that other product of distillation when plants are steam-distilled to release their essential oil. Hydrosol simply means, hydro or water and sol or solution, that is, the water solution that contains some of the water-soluble micro-molecules of essential oil as well as water-soluble plant components.
These micro-molecules of essential oil give the hydrosol its scent and the plant components give the hydrosol its herbal or floral therapy. Remember that hydrosols are not just misters, water to which essential oils have been added. Hydrosols are a unique product, a true part of distillation and cannot be manufactured synthetically.
The micro-drops of essential oil are left intact in the hydrosol. The hydrosol is the first 20% of the distilled non-alcoholic waters. They are used 100% pure as they come out of the still with a strong taste, strong scent and a perfect acid balance of 5.5 –to match human skin.
