Hydrolats (also known as floral water and hydrosols) contain the water soluble compounds of the plant but not the tannic acid and bitter substances. Hydrolats are a product of distillation and can be considered as true partial extracts of the plant material from which they are derived. Their method of preparation, by definition, necessitates that they be totally natural produts with no added synthetic fragrances. Hydrolats are derived from aromatic and other plants by steam distillation. During this process a proportion of the water soluble compounds of the essential oils contained in the plant matter are absorbed and retained by the water.
