Product Description
Our Cinnamic Acid powder is a high-purity natural phenylacrylic acid active ingredient, available in 98% and 99% HPLC grades. Cinnamic Acid (CAS 621-82-9), also known as 3-Phenylacrylic acid or , is a characteristic aromatic plant-derived carboxylic acid widely enriched in cinnamon bark and balsam plants. Featuring a unique conjugated benzene ring and unsaturated acid structure, it possesses dual properties of natural fragrance and biological activity, standing out from conventional hydroxycinnamic acids. It integrates professional UV absorption, tyrosine inhibition whitening, high-efficiency antioxidant, broad-spectrum anti-inflammatory and green antibacterial effects, paired with natural spice enhancement performance. Widely applied in sunscreen and whitening skincare, flavor & fragrance formulation, food preservation, pharmaceutical intermediate synthesis and biomedical research. As a professional bulk Cinnamic Acid supplier, we provide high-purity, low-odor-impurity, stable-batch natural active raw materials for global industrial and scientific research clients.
Cinnamic Acid is the parent structure of multiple phenolic acid active substances, serving as the core precursor of p-coumaric acid, caffeic acid and other hydroxycinnamic acids. Different from derivative phenolic acids, it has exclusive natural UV filtering and tyrosinase inhibitory whitening advantages, plus inherent spice modification capabilities. Its core functional mechanism blocks tyrosinase activity, the key enzyme of melanin synthesis, fundamentally inhibiting melanin production and UV-induced pigmentation. It activates the Nrf2 antioxidant pathway to scavenge skin free radicals and reduce photooxidative aging, while suppressing NF-κB inflammatory response to relieve UV redness and skin irritation. In industrial applications, it delivers mild and lasting cinnamon aroma, improves product fragrance layering, and exerts excellent broad-spectrum antibacterial and fresh-keeping effects. In pharmacology, it shows anti-tumor, lipid-regulating and immune-modulating activity, with high safety and wide compatibility for cosmetic, food and pharmaceutical-grade applications.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium Cinnamic Acid powder adopts low-temperature selective extraction and multi-stage high-precision column chromatography purification technology. We select high-quality natural cinnamon raw materials with stable active content, completely remove plant impurities, residual wax and invalid macromolecular components through gradient elution, and fully retain the complete conjugated molecular structure and biological activity of Cinnamic Acid. The entire production process excludes harmful chemical additives and residual solvents, fully complying with cosmetic-grade, food-grade and pharmaceutical-grade safety standards. The refined purification process eliminates peculiar impurities, maintains pure and mild cinnamon fragrance, and ensures consistent batch purity, uniform white crystalline powder appearance and stable efficacy, meeting strict formula development and experimental requirements of global customers.
Every batch of Cinnamic Acid powder undergoes strict multi-dimensional quality inspection, including HPLC purity testing, UV spectral verification and NMR structural identification to ensure accurate molecular structure and stable high purity. The finished product features low impurity content, excellent solvent solubility, stable fragrance and activity, and outstanding batch consistency. All products comply with international cosmetic additive regulations, food additive safety standards and pharmaceutical intermediate specifications, supporting standardized application in skincare products, flavor & fragrance products, functional foods and biomedical research projects.
We maintain sufficient inventory and complete qualification documents for bulk Cinnamic Acid supply. Whether you need UV whitening and anti-photoaging raw materials for skincare, natural fragrance enhancers and preservatives for food and daily chemicals, or high-purity precursor compounds for phenolic acid pharmacological research, our Cinnamic Acid powder is a cost-effective and reliable bulk raw material choice for global buyers.
Functions & Benefits
Natural UV Filter & Anti-Photoaging (Core Benefit)
Cinnamic Acid has excellent ultraviolet absorption capacity, effectively isolating UV-induced skin photodamage, reducing erythema formation and light aging problems. It assists sunscreen formulas in improving UV protection efficiency, relieves sunburn irritation, and forms a natural light protection barrier for the skin.
Tyrosinase Inhibition & Professional Skin Whitening
As a classic whitening active substance, it specifically inhibits tyrosinase activity, blocks the melanin synthesis chain reaction, reduces melanin deposition and sun pigmentation, fades dull skin and chloasma, and delivers mild, safe and non-irritating brightening and whitening effects, suitable for long-term anti-pigmentation skincare.
Nrf2 Antioxidant & Anti-Inflammatory Soothing
Cinnamic Acid activates the body’s endogenous Nrf2 antioxidant system, efficiently scavenges excess free radicals, inhibits lipid peroxidation and oxidative skin damage. It suppresses NF-κB inflammatory pathway activation, reduces pro-inflammatory factor release, relieves skin redness, sensitivity and chronic low-grade inflammation caused by external stimulation.
Broad-Spectrum Antibacterial & Green Preservation
It exerts significant inhibitory effects on common spoilage bacteria and harmful microorganisms, effectively delaying product oxidative deterioration and microbial reproduction. It can replace part of chemical preservatives, extend the shelf life of cosmetics and foods, and achieve green, safe and residue-free fresh-keeping effects.
Natural Fragrance Enhancement & Odor Modification
With natural warm cinnamon and balsam aroma, Cinnamic Acid optimizes fragrance layering, enhances scent durability, modifies peculiar odors in formulas, and is a high-quality natural spice additive for daily chemical and food products.
Anti-Tumor & Metabolic Regulation Activity
Modern pharmacological studies confirm that Cinnamic Acid inhibits the proliferation and invasion of various malignant tumor cells, induces tumor cell apoptosis, and assists in regulating lipid metabolism and immune balance, showing broad application potential in biomedical and health care fields.
