Step 1: Properties of Essential Oils

Essential oils are steam-volatile organic compounds responsible for fragrance in flowers. Key characteristics:
1. Steam volatile (appreciable vapour pressure)
2. Generally insoluble in water at room temperature
3. Miscible with water vapour in the vapour phase
4. Heat-sensitive (decompose at elevated temperatures)
