Perfume blending is the art and science of combining different fragrance ingredients to create a unique scent. This process involves selecting various essential oils, aromatic compounds, and fixatives to achieve a balanced and harmonious fragrance. Each ingredient contributes its own character, and the skill lies in knowing how to mix them effectively. The blending process typically follows a structured approach, starting with the top notes, which are the initial scents perceived, followed by the middle notes that form the heart of the fragrance, and finally the base notes that provide depth and longevity. Mastering these layers is essential for creating a well-rounded perfume.
