Ferulic Acid Powder

You get the advantage of our whole manufacturing environment. We run 3 separate manufacturing lines with an annual capacity of around 2,000 tons. Our R&D team has expertise in rice bran extraction process with steady trans-ferulic acid concentration from batch to batch. State-of-the-art testing equipment including UPLC, HPLC, ICP-MS and GC-MS provide precise heavy metals, pesticides and microbiological screening. We are certified under ISO9001, ISO22000, FSSC22000, HACCP, HALAL, KOSHER and cGMP. Raw ingredients are handled in accordance with GAP, from low temperature storage to pre-screening for pollutants to eliminate moldy or rotten batches before to processing.

The major input is fresh defatted rice bran, chosen for industrial scalability and cost control. We reject moldy, bug-infested or spoiled-husks and eliminate mud and straw contaminants to minimize oil rancidity during low-temperature storage.

Regular rice bran → general-use powder 98% Conventional Grade:

Refined Grade: Fresh defatted rice bran, pre-screened for pesticides/heavy metals → 99% high purity powder.

Traceable Export Grade Full original documents Separate manufacturing lines to minimize cross contamination

98% Ferulic Acid Powder: Recrystallized once; Has trace isomers; Best cost-performance ratio. Great for regular toners, lotions, mixed skin care, cheap diet powders.

99% High Purity Powder : Multiple gradient recrystallizations+activated carbon decolorization+resin impurity removal Ultra low impurity level Pure white color Slight batch to batch variation High-concentration anti-aging serums, premium whitening products, pharmaceutical intermediates, bespoke research.

β-Cyclodextrin Modified (Water-Soluble): Rapid dissolving in cold water, transparent and stable system, no precipitation. Suitable for oral liquids, clear aqueous serums, liquid functional formulations.

Solubility:

Normal Method: marginally soluble in cold water, easily soluble in hot water, ethanol, methanol, acetone, marginally soluble in vegetable oils

Cyclodextrin modified: Soluble in cold/hot water; clear solution with no precipitation

Stability:

• Temperature: Process at ≤65°C; avoid extended exposure over 80°C to prevent oxidation and loss of action.
• pH: 4.0-7.2 stable. Unsaturated double bond damaged by strong acids/alkalis.
• Light - Dry powder is durable when stored in sealed containers shielded from light; aqueous solutions are UV sensitive
• Hygroscopicity: Higher purity means less moisture absorption; vacuum sealed aluminum foil bags + cardboard drums have a shelf life of 24 months (unopened)

Our rice bran extraction is a careful nine-step process:

Raw Material Pretreatment: Screening removes straw, stones, moldy particles, low-temperature hot air drying regulates moisture content, defatting is done by pressing or leaching, grinding to a particle size of 20-30 mesh improves extraction efficiency.

Alkaline Extraction: Ester bonds of cell walls are cleaved by dilute sodium hydroxide to release bound ferulic acid in free form; bran residue is separated by plate-and-frame filtration and mother liquid is collected.

Acidification & Precipitation: Bring to pH of acidity; free ferulic acid crystallizes; filter to produce moist crude crystals.

Crude washing and impurity removal: several purified water washes to remove salts, sugars, water soluble pigments and small molecule contaminants.

Solvent Recrystallization & Fractional Refining: Crude product dissolved in hot ethanol; activated carbon reflux eliminates colors; hot-filter and gradual cool crystallization. 98% grade needs single recrystallization; 99% grade requires serial recrystallization of ethanol gradient and adsorption of macroporous resin for thorough purification.

Dehydration & Low Temperature Vacuum Drying: Centrifuge to remove solvent; dry under vacuum <65°C, sheltered from light/air to avoid oxidation.

Cyclodextrin Inclusion Modification (custom): high-purity ferulic acid is dissolved in ethanol, and then mixed with β-cyclodextrin aqueous solution; molecular inclusion is completed by high-pressure homogenization; and spray-drying to get cold-water-soluble modified powder.

Sieving & Batch Mixing Crush and sieve to 80-100 or 200 mesh. Mix well in three-dimensional mixer for homogeneous content, color and particle size.

Packaging & Storage: Vacuum sealed lightproof aluminum foil bag + 25kg moisture-proof cardboard drum. Full content, physicochemical, heavy metal, microbiological testing before warehousing.

• Cosmetics: anti-age serums with high concentrations, whitening treatments, UV protection formulae, antioxidant toners/lotions
• Pharmaceuticals: Raw material for research, intermediary for synthesis
• Nutraceuticals, dietary supplements, oral liquid, antioxidant powder formulations
• Food & Beverage: Natural antioxidant booster, useful substance for controlling oxidation

Each batch is tested by third parties for purity, potency, heavy metals, pesticide residues and microbes. We are certified by ISO9001, ISO22000, FSSC22000, HACCP, HALAL, KOSHER and cGMP. We use UPLC,HPLC,ICP-MS,GC-MS and ELISA for accurate verification in our quality inspection laboratory. Full traceability from the raw material source to the finished product guarantees transparency and conformity with international standards.

Standard Packaging: 1kg aluminum foil bags, 25kg cartons, 25kg drums

Custom Options: Available for OEM/ODM clients

Shipping Methods: Air freight, sea freight, express courier (DHL, FedEx, UPS)

Lead Time: 7-15 working days after order confirmation

Q: Is your ferulic acid natural or synthetic? Do you have source traceability?

A: We have both. Rice bran, rice husk, angelica root, ferula root are found in nature. Synthetic: vanillin and malonic acid. We have batch records, raw material traceability and separate lines of manufacturing to avoid cross-contamination.

Q: Do you test heavy metals before production?

A: Yes. All source materials are inspected for heavy metals, pesticides and impurities before feeding. Unqualified batches are rejected outright, guaranteeing steady purity and consistent impurity profiles.

Q: What's the difference between 98% and 99%? Have you have water soluble kinds?

A: 98 % single recrystallization, economical for the general formula. 99% ultra-low impurities, numerous recrystallizations, suitable for premium goods. Our inclusion form of β-cyclodextrin provides outstanding solubility in cold water for clear serums and oral drinks.

Q: Why does my solution turn yellow over time?

A. The discolouration is due to oxidation or reaction with metal ions. Add chelating agents (Disodium EDTA for example), nitrogen blanket during manufacture and store in opaque airless container.

Q: What is the appropriate dose for topical formulations?

A: 0.5–1.0% in combination with 15% vitamin C and 1% vitamin E gives maximal synergistic protection.
