petitgrain concrete

Petitgrain concrete is a natural aromatic substance obtained from the leaves of Citrus aurantium, specifically referred to as citrus aurantium leaf concrete. It appears as a fragrant oily concrete that exhibits prominent floral odor characteristics. Synonyms encompass terms such as petitgrain oil absolute, citrus aurantium leaf concrete, and bitter orange oil, among others. This compound is broadly classified as an essential oil derived from citrus leaves rather than fruits. Its organoleptic profile includes fresh, floral notes useful in perfumery. More information about its chemical identity and properties can be accessed via PubChem. Extraction typically involves solvent-based methods on freshly harvested leaves and green twigs of the bitter orange tree (Citrus aurantium), yielding the concrete form before further processing in fragrance production.

Petitgrain concrete originates biologically from the leaves of the Citrus aurantium plant, commonly known as bitter orange. Owing to its complex and fresh floral aromatic profile, it finds main applicability as a fragrance agent in perfumery formulations. Its scent resembles aspects of bergamot, contributing to refined and fresh top or middle notes in compositions. The International Fragrance Association (IFRA) in their (Global) Code of Practice includes petitgrain concrete among regulated materials to ensure safe usage levels in fragrances. It is generally not used for flavoring purposes but rather valued for its olfactory qualities in luxury and fine fragrance products.

Petitgrain concrete demonstrates solubility in water estimated at approximately 20.12 mg/L at 25 °C, indicating slight water solubility which can influence its incorporation in fragrance emulsions or blends. Its physical form is typically a viscous, oily concrete derived via solvent extraction of fresh leaves. The floral and fresh odor character is determined by its complex mixture of volatile organic compounds. These properties are essential considerations for perfumers and formulators, as they affect volatility, blending behavior, and scent diffusion in finished products. Stability and solubility profiles also determine optimal concentration limits and compatibility with other fragrance ingredients.
