Heart Accord Builder

A heart accord builder is an aroma material used to develop the central character and body of a fragrance. These materials often provide floral, fruity, spicy, aromatic or creamy facets that become noticeable after the opening begins to soften. Perfumers use heart accord builders to add volume, complexity and continuity between the top and base notes. They can strengthen a specific theme, smooth transitions and prevent a composition from feeling hollow or disconnected. Their effect depends on the formula, so dosage should be adjusted according to the desired prominence and balance.
