Gallic Acid is a white powder, it is a key precursor in the biosynthesis of hydrolysable tannins and serves as a powerful free radical scavenger. It is commonly used in pharmaceuticals, cosmetics, food & beverages, research laboratories, and industrial applications due to its proven antioxidant, anti-inflammatory, antimicrobial, antiviral, and potential anticancer activities.

Benefits and Biological Activities
Gallic Acid is one of the most studied natural antioxidants and exhibits multiple evidence-based properties:
Strong Antioxidant Activity:
Scavenges free radicals, inhibits lipid peroxidation, and protects cells from oxidative stress more effectively than many synthetic antioxidants.
Anti-Inflammatory Effects:
Modulates inflammatory pathways and reduces pro-inflammatory cytokines.
Antimicrobial Properties:
Active against bacteria (e.g., Staphylococcus aureus, E. coli, Pseudomonas), fungi, and viruses.
Potential Anticancer Effects:
Induces apoptosis in cancer cells and inhibits tumor growth in preclinical studies.
Neuroprotective Role:
Supports brain health by crossing the blood-brain barrier and protecting against neurodegenerative conditions.
Metabolic Support:
May help regulate blood sugar and support liver function.
Primary Applications of Gallic Acid
Food & Beverage Industry:
Used as a precursor for antioxidants like propyl gallate (E-310), octyl gallate, and dodecyl gallate to prevent rancidity in oils, fats, and processed foods.
Pharmaceuticals:
Active pharmaceutical ingredient (API) in antioxidant formulations, astringents, and topical preparations for psoriasis or hemorrhoids.
Cosmetics & Personal Care:
Natural preservative, skin-soothing agent, and UV protectant in creams, serums, and anti-aging products.
Analytical Chemistry:
Standard for total phenolic content determination (Folin-Ciocalteu assay).
Research & Industrial:
Reagent in biochemistry, ink/dye production, and metal chelation processes.
Frequently Asked Questions (FAQs)
What is Gallic Acid?
Gallic Acid is a naturally occurring trihydroxybenzoic acid and phenolic compound found in many plants. It is a strong antioxidant and the building block for gallates and hydrolysable tannins.
What is the difference between anhydrous and monohydrate Gallic Acid?
Anhydrous (CAS 149-91-7) contains no water of crystallization, while monohydrate (CAS 5995-86-8) contains one molecule of water. Both forms have identical biological activity; monohydrate is often preferred for stability in humid conditions.
Is Gallic Acid safe for cosmetic use?
Yes. Gallic Acid is registered under INCI and recognized as safe by regulatory bodies when used within recommended concentrations. It is widely used for skin-brightening and anti-aging effects.
Does Gallic Acid have antioxidant properties?
Yes, it is one of the most potent natural phenolic antioxidants. It scavenges free radicals, inhibits lipid peroxidation, and protects cells from oxidative damage more effectively than many synthetic alternatives.
How should Gallic Acid be stored?
Store in a cool, dry, dark place in tightly sealed containers. It is sensitive to light and oxygen, which can cause gradual browning.
