The fragrance industry uses many natural ingredients, such as lavender, jasmine, sandalwood and centifolia oils. The perfumers’ palette also contains thousands of synthetic molecules. Since the development of the first synthetic F&F ingredients in the late 19th century, the chemical processes have evolved significantly. There are evermore synthetic options for perfumers and flavorists. These synthetic materials have allowed fragrances and flavors to become mainstream and accessible to mass markets.1 They go into everything from high-end designer perfumes to laundry detergents and car scents. Today, industry estimates are that petrol-derived ingredients comprise over half the raw materials used in flavors and fragrances.
