Cinnamaldehyde (Cinnamon Aldehyde)
Antimicrobial, flavoring agent, fragrance component, corrosion inhibitor, agricultural fungicide
Cinnamaldehyde (cinnamic aldehyde) is the principal aromatic constituent of cassia oil (75-90%) and cinnamon bark oil (60-75%), responsible for their characteristic warm, spicy, cinnamon-like aroma. As a purified natural isolate, cinnamaldehyde is a pale yellow to yellow-green liquid with an intensely warm, sweet-spicy, cinnamon odor and a burning, aromatic taste. It is derived from cassia oil through chemical treatment with sodium bisulfite to form a water-soluble adduct, separation from terpenes, then regeneration through alkaline hydrolysis, followed by fractional vacuum distillation to achieve >98% purity. Cinnamaldehyde is extensively used in the flavor and fragrance industry, and increasingly as a natural antimicrobial and agricultural fungicide. Fresure supplies both natural (ex-cassia) and synthetic cinnamaldehyde with batch-specific purity verification.

GRAS flavoring substance (FEMA GRAS 2286). Primary flavoring agent for cinnamon and cassia profiles in confectionery (hard candies, chewing gum), baked goods (cinnamon rolls, cookies, pastries), beverages (cola, spiced tea, liqueurs), and processed foods. Also used in savory spice blends for meat products and ethnic cuisines.
Warm, spicy note in oriental, amber, and gourmand fragrance compositions. Used in perfumes, colognes, scented candles, potpourri, air fresheners, and holiday-themed consumer products. Provides excellent fixation and long-lasting spicy warmth. Often combined with vanilla, clove, and nutmeg for 'holiday spice' profiles.
Natural fungicide and bactericide in agricultural and horticultural applications. Effective against a broad spectrum of plant pathogenic fungi (Fusarium, Botrytis, Rhizoctonia, Colletotrichum) and bacteria. Used in post-harvest fruit and vegetable protection, seed treatment, and greenhouse disease management. Approved for organic production.
Effective corrosion inhibitor for carbon steel, aluminum, and other metals in acidic environments (acid pickling, oil well acidizing). Natural antimicrobial preservative in industrial water systems, metalworking fluids, and paint formulations. Intermediate in the synthesis of cinnamyl alcohol and other fragrance chemicals.

Custom packaging and private labeling available upon request.
Store in tightly sealed, full containers in a cool, dry place protected from light. Cinnamaldehyde is air-sensitive and oxidizes to cinnamic acid upon prolonged air exposure; minimize headspace and blanket with nitrogen for long-term storage. Shelf life: 2 years under recommended conditions.
Under recommended storage conditions — tightly sealed in a cool, dry environment away from direct sunlight — Cinnamaldehyde remains stable for 2 to 3 years. Monitor for any changes in aroma, color, or viscosity before use in production batches.
Cinnamaldehyde is from the . This method preserves the full spectrum of volatile aromatic compounds and bioactive constituents that define the oil''s therapeutic and sensory profile.
Every shipment includes a Certificate of Analysis (COA) detailing the batch-specific chemical profile (GC/MS or GC-FID), physical parameters (specific gravity, refractive index, optical rotation), and organoleptic assessment. Material Safety Data Sheet (MSDS/SDS) is also provided. Additional documentation — including GC/MS chromatograms, pesticide residue analysis, heavy metal testing, and allergen statements — is available upon request.
