Ferulic Acid

Ureda Naturals Natural Ferulic Acid is a rice-bran-derived ferulic acid ingredient manufactured for cosmetic formulation, antioxidant system development and selected natural vanillin production routes.

The product is identified as Ferulic Acid / trans-Ferulic Acid, CAS No. 537-98-4, with an assay of not less than 99.0%. It is supplied as a white or pale-yellow powder with no noticeable odor or taste.

Key Specifications

Natural Ferulic Acid Compared with Rice Bran Extract

Natural Ferulic Acid and rice bran extract should not be treated as interchangeable materials.

Natural and synthetic ferulic acid have the same chemical identity when they contain the same molecule. CAS No. 537-98-4 identifies the chemical substance, while the natural-origin distinction depends on rice-bran source, manufacturing route and traceability.

Quality Attributes and Analytical Control

Assay: ≥99.0%

Assay defines the amount of ferulic acid available for formulation or downstream conversion calculations. It is especially important when the customer needs a defined active concentration, consistent batch charging or a reproducible substrate for natural vanillin development.

Assay does not independently describe moisture, residual solvent, color, solid form or finished-formula stability.

Loss on Drying: ≤0.5%

Loss on drying is a physical-condition control. A low value supports consistent weighing, reduces moisture-related caking and improves powder handling during storage and batching.

Melting Point: 170–174°C

The melting range provides an additional identity and solid-state consistency check. When reviewed together with HPLC assay, it can help identify incomplete purification, unexpected crystal behavior or lot-to-lot thermal differences.

Melting point is not a direct measurement of antioxidant activity.

Appearance, Odor and Taste

The specified material is a white or pale-yellow powder with no noticeable odor or taste. These characteristics are relevant when the ingredient is used in clear cosmetic products, low-odor formulations or flavor-related development.

Ferulic acid assay is typically controlled by reversed-phase HPLC with UV or diode-array detection. HPLC helps distinguish the target ferulic acid peak from other phenolic components that may be present in less-purified rice-bran materials.

Cosmetic Formulation: Solubility, pH and Photostability

Antioxidant Systems

Natural Ferulic Acid is used in the development of antioxidant serums, creams, emulsions, botanical active blends, vitamin C formulations and vitamin C–vitamin E systems.

The final formulation result depends on solvent selection, pH, temperature, oxygen exposure, light and packaging. The raw-material assay alone cannot predict finished-product stability.

Water-Based Formulas

Free ferulic acid has limited intrinsic water solubility. Direct addition to water may cause incomplete dissolution, temporary clarity followed by precipitation or crystal formation during cooling.

1. Select a suitable solvent or neutralization system.
2. Prepare a concentrated ferulic acid phase.
3. Confirm dissolution before dilution.
4. Add the phase under controlled mixing.
5. Define the final pH after the ferulic acid phase is uniform.
6. Check clarity and crystallization after cooling.
7. Evaluate assay retention, color and clarity under light and temperature stress.

Vitamin C and Vitamin E Systems

When used with ascorbic acid and tocopherol, the development team should monitor active retention, color change, clarity, precipitation, pH drift and stability under light and accelerated-temperature conditions.

UV Positioning

Ferulic Acid is not a standalone regulated UV filter. Its role in cosmetic development is associated with antioxidant and photostability-support systems.

Natural Vanillin Development

Ferulic acid is a defined precursor for selected natural vanillin bioconversion routes. Depending on the microorganism, enzyme system and process conditions, ferulic acid may be converted toward vanillin through intermediate steps.

Vanillic acid and vanillyl alcohol may also appear as competing or downstream products, so a high assay should be supported by process-specific analytical monitoring.

Storage and Quality Documentation

Natural Ferulic Acid should be stored sealed, dry and protected from direct light.

• Minimize package opening time.
• Avoid humid handling areas.
• Use clean and dry transfer equipment.
• Prevent unnecessary UV exposure.
• Reseal the remaining material promptly.
• Avoid excessive heat during processing.
