Rose water Phoenicians considered large public rose gardens to be as important as croplands such as orchards and wheat fields. Rose perfumes are made from rose oil, also called "attar of roses", which is a mixture of volatile essential oils obtained by steam-distilling the crushed petals of roses. Rose water is a by-product of this process. The cultivation of various fragrant flowers for obtaining perfumes, including rose water, may date back to Sassanid Persia, where it was known as "golāb" (Middle Persian: گلاب), from "gul" (rose) and "ab" (water). The term was adopted into Byzantine Greek as "zoulápin". The process of creating
Essential oil peel and low cost to grow and harvest the raw materials, citrus-fruit oils are cheaper than most other essential oils. Lemon or sweet orange oils are obtained as byproducts of the citrus industry. Before the discovery of distillation, all essential oils were extracted by pressing. Most flowers contain too little volatile oil to undergo expression, but their chemical components are too delicate and easily denatured by the high heat used in steam distillation. Instead, a solvent such as hexane or supercritical carbon dioxide is used to extract the oils. Extracts from hexane and other hydrophobic solvents are called "concretes", which
