章節 73: Gathering At The Garden

Song Jia continued to teach Crystal about how to make perfumes.

"Heart notes' function is to retain some of the top notes' aroma while also introducing new scents to deepen the experience. Sometimes referred to as middle notes, the heart notes also serve as a buffer for the base notes, which may not smell as pleasant on their own. Because they make up around 70 percent of the total scent, heart notes usually last longer than top notes. Heart notes appear as the top notes start to fade and remain evident for the full life of the fragrance. Heart notes include full-bodied, aromatic floral oils like jasmine, geranium, neroli and ylang-ylang, as well as cinnamon, pepper, pine, lemongrass, black pepper and cardamom.
