Orange flower oil, bitter, also known as neroli and neroli bigarade, is derived from the blossoms of the bitter orange tree (Citrus aurantium). This essential oil is characterized by its fresh, floral, and slightly citrusy aroma, which can add a bright and uplifting quality to fragrance compositions. In perfumery, it is often used in floral and citrus accords, providing a complex and nuanced scent profile that can enhance the overall character of a fragrance. Orange flower oil typically sits in the heart or top notes of a formula, contributing to the initial impression and the lasting floral aspects of the scent. It is important to note that, like many floral oils, orange flower oil can be a potential allergen for some individuals, and perfumers should be mindful of this when formulating. Additionally, it may be subject to specific regulations regarding its use in cosmetic products, as outlined by organizations such as IFRA, which provides guidelines to ensure safety in fragrance formulations. — AI-generated summary, 2026-09-02.
Bitter orange flower oil (neroli) opens with a bright, sparkling citrus-floral character — fresh orange peel lifted by clean white-floral petals. The heart is green and slightly bitter with a honeyed, waxy petal facet, drying down to a soft, warm floral trail.AI · claude-opus-4-7
