FORMULATION AND EVALUATION OF HERBAL CREAM
Rose oil, meaning either rose otto (attar of rose, attar of roses) or rose absolute, is the essential oil extracted from the petals of various types of rose. Rose ottos are extracted through steam distillation, while rose absolutes are obtained through solvent extraction or supercritical carbon dioxide extraction, with the absolute being used more commonly in perfumery. Even with their high price and the advent of organic synthesis, rose oils are still perhaps the most widely used essential oil in perfumery.
Two major species of rose are cultivated for the production of rose oil:
• Rosa damascena, the damask rose, which is widely grown in Bulgaria, Turkey, Russia, Pakistan, India, Uzbekistan, Iran and China
• Rosa centifolia, the cabbage rose, which is more commonly grown in Morocco, France and Egypt
