Hydrolates: a review on their volatiles composition, biological properties and potential uses

An hydrolate (also known as hydrosol, floral water, aromatic or herbal water) is a distillate which product of condensation obtained after an essential oil distillation isolation procedure. Hydrolates are colloidal suspensions composed continuous phase, the distilled and dispersed emulsion droplets water-soluble components, namely oxygen-containing compounds. The movement towards circular economy, has increased interest in industry co-products, such hydrolates. composition were mostly studied based on their volatile constituents. Moreover, they showed diverse range biological properties, with potential application food, beverages, cosmetic pharmaceutical industries, well agroforest sector. Nevertheless, information fragmented under different hydrolates designations. In present review, main components 362 from 194 species 50 families described, corresponding detailed. Additionally, methodologies extraction analysis surveyed, characteristics traditional uses. This review also describes properties attributed to and, according these
