d-Limonene (CAS 5989-27-5) is a synthetic aroma chemical commonly used in perfumery for its fresh, citrusy scent reminiscent of oranges and lemons. It is often employed as a top note in fragrance formulations, providing a bright and uplifting character that can enhance the overall olfactory profile of a scent. d-Limonene is versatile and can be found in a variety of fragrance types, including citrus, floral, and aromatic compositions. In addition to its aromatic properties, it can also serve as a solvent or carrier for other fragrance ingredients. However, it is important to note that d-Limonene is classified as a potential allergen and is subject to regulatory scrutiny, particularly in the European Union, where it is included in the list of allergens that must be declared on cosmetic product labels. As such, perfumers must consider its concentration in formulations to ensure compliance with safety regulations and to minimize the risk of allergic reactions in sensitive individuals. — AI-generated summary, 2026-09-02.
