neroli fragrance

Neroli fragrance is an aromatic extract obtained from the blossoms of the bitter orange tree, known scientifically as Citrus aurantium. It is classified as a complex mixture of volatile organic compounds responsible for its distinctive floral odor, often described as fresh, sweet, and slightly citrusy. Synonyms include bitter orange flower fragrance and bitter orangeflower fragrance, reflecting its botanical source. The material appears as a clear liquid with specific gravity ranging from 0.94 to 0.98 at 25 °C and a refractive index between 1.47 and 1.49 at 20 °C. This fragrance oil is valued in perfumery and is represented in controlled vocabulary databases such as PubChem. Neroli fragrance is typically obtained by steam distillation or solvent extraction from bitter orange blossoms, contributing to a wide range of fragranced consumer products.

Neroli fragrance naturally occurs in the flowers of the bitter orange tree and is primarily utilized in fragranced products spanning personal care, household, and fine fragrance industries. It lends its characteristic floral note to blends aiming to evoke bouquet, citrus, and exotic flower themes such as jasmine, tuberose, and orchid. The fragrance ingredient is regulated under IFRA (Global), which provides guidelines on maximum usage levels due to phototoxicity considerations stemming from components like bergapten. Neroli's versatility also includes incorporation in formulations evoking passion fruit, magnolia, or sweet pea odors, highlighting its applicability in broad scent profiles.

Neroli fragrance exhibits a specific gravity between 0.94 and 0.98 at 25 °C, indicating a density slightly lower than water. Its refractive index ranges from 1.47 to 1.49 at 20 °C, reflecting its optical properties important for quality control and formulation consistency. The compound dissolves readily in alcohol and paraffin oil, enabling its blending into a variety of base ingredients used in perfumery. It is insoluble in water, which affects its dispersion and stability in aqueous formulations. These physicochemical traits influence handling, storage, and application techniques, ensuring compatibility with diverse product types while maintaining olfactive integrity.

Safety in use information

Category:
fragranced products of all types
IFRA Critical Effect:
Phototoxicity
IFRA fragrance material specification:
	Where the bergapten (5-methoxypsoralen) content of all relevant oils present in a compound has been determined, it is recommended that for applications on areas of skin exposed to sunshine, excluding bath preparations, soaps and other products which are washed off the skin, the total level of bergapten in the consumer products should not exceed 0.0015% (15 ppm). This is equivalent to 0.0075% (75 ppm) in a fragrance compound used at 20% in the consumer product. Where the level of bergapten has not been determined by appropriate methods, the limits specified in the guidelines on individual oils should apply. In those cases, where such oils are used in combination with other phototoxic ingredients, the additive effect has to be taken into consideration and the use levels have to be reduced accordingly. The sum of the concentrations of all phototoxic fragrance ingredients, expressed in % of their recommended maximum level in the consumer product, shall not exceed 100.
Recommendation for neroli fragrance flavor usage levels up to:
	not for flavor use.
