Natural Ferulic Acid

Our ferulic acid is purely derived from natural grain processing by-products without synthetic intervention. Fresh rice bran and wheat bran will undergo strict inspections for heavy metals, aflatoxins and pesticide residues immediately after collection. We retain complete planting and production records for each batch, providing official origin certificates to support your clean-label product promotion and market filing.

We offer three mainstream grades to match different application scenarios: cosmetic grade with uniform particle size and stable color for skincare formulas, food grade with strict microbial control for functional food production, and organic grade sourced from certified organic grain materials. Tiered product specifications help customers select targeted materials according to product positioning and regional regulations.

This plant-derived ingredient features excellent solubility in ethanol and propylene glycol, with slight solubility in cold water and improved dissolution in hot water. For aqueous formulas, pre-dissolving in propanediol at 40–50°C can effectively avoid crystallization and ensure uniform formula dispersion.

In terms of stability, Natural Ferulic Acid maintains stable activity within pH 4.0–7.0 (optimal in weak acidic environments). High temperature above 70°C, long-term UV exposure and humid air will cause oxidation, discoloration and activity loss. Therefore, sealed, light-proof and dry storage is required for both finished products and formulated materials to extend service life.

We adopt mild biological enzymatic production to maximize the retention of active ingredients.

After raw material purification and cleaning, compound cellulase and food-grade alkali are used to break the ester bond between ferulic acid and plant polysaccharides at low temperature, realizing effective release of active substances without thermal damage.

Crude crystals are precipitated via pH adjustment, then purified through multi-stage filtration and macroporous resin adsorption to remove impurities like tannins and polysaccharides.

Gradient recrystallization further eliminates inactive cis-isomers and inorganic salts to improve trans-isomer purity.

After low-temperature vacuum drying, the finished powder is pulverized and sieved into 80–100 mesh for capsules and 200 mesh ultrafine powder for transparent serums.

Uniform batch blending and nitrogen-filled vacuum packaging ensure consistent quality of every batch.

We implement full-process quality control for all products. Each batch is delivered with an official COA, including detailed HPLC data of trans and cis isomer content, microbial test results and residual solvent detection data that fully comply with ICH Q3C standards. All microbial indicators meet food and cosmetic dual-grade requirements.

Complete batch traceability records cover every production link from raw material incoming inspection to finished product delivery. Authorized third-party testing is available to provide independent verification, effectively supporting customer product audits and global regulatory registration.

Standard packaging adopts vacuum-sealed aluminum foil inner bags matched with 25kg food-grade fiber drums, which are light-proof, oxygen-proof and moisture-proof, suitable for long-distance international transportation. We provide customized solutions including 1kg small sample packages for laboratory R&D and enhanced nitrogen-filled sealing for high-humidity area shipments.

We support flexible global logistics: express delivery for fast sample delivery, and sea freight for bulk orders. All shipments are equipped with complete documents such as COA, MSDS, packing list and origin certificates, with additional non-GMO and allergen statements available for regulated markets.

Q1: Is your ferulic acid natural plant-derived or synthetic?

A1: 100% natural grain-derived via enzymatic extraction, no synthetic ingredients. We provide botanical origin certificates and C14 test reports to prove pure bio-based properties.

Q2: How do you guarantee high trans-isomer purity?

A2: We adopt gradient recrystallization technology to separate inactive cis-isomers. Each batch HPLC report clearly marks the content of two isomers to ensure effective ingredient content.

Q3: What measures prevent ingredient oxidation during production?

A3: The whole process is controlled below 55°C with full light shielding and nitrogen protection, which perfectly protects the phenolic structure and avoids activity oxidation.

Q4: Is this ingredient suitable for sensitive skin skincare products?

A4: Yes. It is non-irritating to the skin and can effectively relieve UV-induced redness, ideal for sensitive skin care and post-repair formulas.

Q5: What is the optimal addition ratio for serum formulas?

A5: The recommended addition concentration is 0.5–1.0%. It works best when compounded with 15% Vitamin C and 1% Vitamin E for synergistic antioxidant effects.
