Middle Notes (Heart Notes)
The middle notes appear once the top notes have evaporated. They form the main body of the fragrance and are responsible for its character and personality. Middle notes are more rounded and often floral or spicy. They last longer than top notes, typically up to a few hours. Standard middle notes include floral scents (e.g., rose, jasmine, ylang-ylang), spices (e.g., cinnamon, clove), and herbal notes (e.g., geranium, lavender).
Base Notes
These are the fragrance's foundation and are noticeable after the top and middle notes have dissipated. Base notes are rich, deep, and long-lasting, providing a lasting impression. They often contain heavier ingredients such as wood, resins, and animal notes. Base notes can linger for several hours or even days. Typical base notes include woods (e.g., sandalwood, cedar), vanilla, musk, patchouli, amber, and various resins (e.g., benzoin, labdanum).
