Description

Bourgeonal is a high-purity aromatic aldehyde fragrance compound, also known by its CAS number 18127-01-0. It is valued for its powerful, fresh, and floral scent reminiscent of lily of the valley (muguet), making it a cornerstone material in modern perfumery. This compound is essential for fragrance manufacturers and flavorists seeking to create sophisticated, natural-smelling accords in fine fragrances, personal care products, and select flavor applications.

Application

• Fine Fragrance Formulation: A key component in creating fresh, floral, and green top notes for perfumes, eaux de toilette, and colognes.
• Personal Care & Cosmetics: Used as a fragrance ingredient in soaps, shower gels, lotions, shampoos, and deodorants to impart a clean, floral character.
• Household & Industrial Fragrances: Incorporated into air fresheners, detergents, fabric softeners, and cleaning products for a pleasant and lasting scent.
• Flavor & Fragrance (F&F) Synergy: Employed in flavor compositions where subtle floral notes are desired, often in conjunction with fruity or sweet profiles.
• Aroma Chemical Intermediate: Serves as a building block for the synthesis of more complex fragrance molecules and specialty chemicals.

Quality Control

Our Bourgeonal is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. It is tested against rigorous in-house specifications that assess identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing results for key parameters such as purity (by GC), specific gravity, refractive index, and olfactory profile is provided with each shipment to guarantee it meets the exacting standards of the fragrance industry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) when in partially used containers to maintain stability and prevent degradation.
