Fragrance in simple terms, is a chemical mixture that has a smell. It can be made from natural or synthetic ingredients. The terms fragrance and perfume are often used interchangeably, however there is a difference between both. Fragrance is a broad term used to indicate any pleasant or distinctive odour which is used in a wide range of products, including perfumes, soaps, detergents, air fresheners and scented candles. Perfume refers to a scented liquid or spray containing a higher concentration of fragrance which usually takes the form of cologne, eau de parfum, eau de toilette or simply parfum.
A renowned French perfumer, Jean Carles (1892 – 1966) coined the term ‘fragrance pyramid’ to indicate the manner of visualising the different tones that make up a perfume. The fragrance pyramid is represented as a triangle consisting of the following layers:
- Top Notes: Also known as the Head Notes, these represent the initial scents which are perceived immediately after applying a fragrance. They are often fresh, light and zesty and evaporate quickly. They are designed to catch the attention and further explore the scent.
- Middle Notes: Also known as Heart Notes, they are noticeable a few minutes after the application of the Top Notes. These notes make up the core of the scent and contribute it to its overall character. They can be floral, fruity or spicy and often provide complexity to the fragrance.
- Base Notes: Also known as the foundation of the fragrance, they are noticeable after the top notes and middle notes have faded, usually after several hours of application. They are the longest lasting and the most stable tones. They are typically rick, woody or musky and provide a sense of depth and warmth.
The fragrance pyramid is used as a guide at the time of creation of new perfumes. The aroma chemicals in the fragrance enhance and balance the overall composition of the fragrance. They can be used to highlight specific notes or create unique combinations by contributing specific scent characteristics to each layer/ note.
