Food Flavor, Pharmaceutical & Industrial Grade trans-Cinnamaldehyde CAS 104-55-2

Cinnamaldehyde (also named Cinnamic Aldehyde, 3-Phenyl-2-propenal, CAS: 104-55-2, EINECS: 203-213-9, HS Code: 2912299000) is a pale yellow to yellow transparent liquid with a strong characteristic cinnamon aroma, with molecular formula  and molecular weight 132.16. We supply food grade, cosmetic grade, feed grade and industrial grade products, including both synthetic grade and natural-extracted grade derived from cinnamon oil. It is readily soluble in ethanol, ether and most organic solvents, slightly soluble in water, featuring outstanding antibacterial, antifungal, antioxidant and flavor-enhancing properties. Widely used as edible flavor, natural preservative, daily chemical fragrance, feed growth promoter and pharmaceutical intermediate across food, personal care, animal husbandry, pharmaceutical and industrial industries.

Applications
Food & Beverage Flavor Industry (Core Application)
A classic natural-equivalent edible spice widely used in bakery products, candies, chewing gums, cola beverages, condiments and instant food. It delivers authentic cinnamon aroma and taste, and also functions as a natural preservative to inhibit bacteria and mold, extend product shelf life, and complies with GB 2760, FCC and FDA food additive safety standards.
Daily Chemical & Personal Care
Added to toothpastes, mouthwashes, soaps, perfumes, skincare products and hair care items to provide warm cinnamon fragrance. It also delivers antibacterial and deodorizing effects in oral care products, and promotes microcirculation in skincare formulations, being a common functional raw material for oral care and aromatic personal care products.
Feed & Animal Husbandry
Feed grade cinnamaldehyde serves as a natural antimicrobial growth promoter for livestock, poultry and aquaculture. It inhibits harmful intestinal bacteria, improves feed conversion ratio, promotes animal growth, and effectively replaces part of antibiotic additives, fully matching the global antibiotic-free breeding development trend.
Pharmaceutical & Healthcare Industry
Key intermediate for synthesizing cardiovascular drugs, antibacterial agents and anti-inflammatory drugs. It is also used in external disinfectants, moxibustion patches and warming patches, with functions of promoting blood circulation, antibacterial and anti-inflammatory effects, and is widely applied in traditional Chinese medicine preparations and health care products.
Industrial Sterilization & Preservation
Industrial grade product is used as high-efficiency bactericide and mildew inhibitor for industrial circulating water, coatings, adhesives, leather and paper products. It inhibits microbial growth, prolongs the service life of industrial products, and also acts as a sterilization additive in oilfield exploitation to improve production efficiency.
Agricultural & Plant Protection
Raw material for botanical fungicides and insect repellents. It prevents and controls fungal diseases of crops, repels pests, and features low toxicity, easy degradation and no residue, conforming to the requirements of green agriculture and pollution-free planting.
