Gallic acid, chemically known as 3,4,5 - Trihydroxybenzoic acid, has a molecular formula of C₇H₆O₅ and a molecular weight of approximately 170.12 g/mol. It appears as a white to light - yellow crystalline powder. This product is compliant with international quality standards, ensuring its high purity and stability. The melting point of gallic acid is around 250 - 252°C (decomposes). It is sparingly soluble in cold water but soluble in hot water, alcohol, and ether.
1. **Antioxidant in the Food Industry**: Gallic acid is widely used as an antioxidant in the food industry. It can prevent the oxidation of fats, oils, and other food components, thereby extending the shelf - life of food products. For example, it can be added to edible oils to prevent rancidity.
2. **Pharmaceutical Applications**: In the pharmaceutical field, gallic acid has various biological activities. It has anti - inflammatory, antibacterial, and antiviral properties. It can be used in the development of drugs for treating inflammatory diseases, skin infections, and even some viral diseases.
3. **Cosmetics**: Due to its antioxidant and anti - aging properties, gallic acid is also used in cosmetics. It can protect the skin from free - radical damage, reduce wrinkles, and improve skin texture.
4. **Chemical Synthesis**: It serves as an important intermediate in chemical synthesis. It can be used to synthesize other valuable compounds, such as esters and derivatives with specific functions.
1. **Food Industry**: When using gallic acid as an antioxidant in food, the recommended dosage is usually in the range of 0.01% - 0.1% (w/w) depending on the type of food product. First, dissolve the appropriate amount of gallic acid in a small amount of hot water or an appropriate solvent. Then add the solution to the food during the manufacturing process.
2. **Pharmaceutical Applications**: In drug formulation, the dosage and usage method should be determined according to the specific drug development requirements and relevant clinical trials. It may be formulated into tablets, capsules, or topical creams.
3. **Cosmetics**: For cosmetic products, gallic acid can be added to creams, lotions, or serums. The concentration is typically in the range of 0.5% - 5%. Mix it well with other cosmetic ingredients during the production process.
1. **Edible Oil Preservation**: A food manufacturing company added 0.05% (w/w) of gallic acid to their sunflower oil. They stored the oil under normal storage conditions for 6 months. After the storage period, the oil showed significantly less oxidation compared to the control group without gallic acid. The peroxide value and anisidine value, which are indicators of oil oxidation, were much lower in the oil with gallic acid.
2. **Treatment of Skin Infections**: A pharmaceutical research group developed a topical cream containing 1% gallic acid for treating mild skin infections. In a clinical trial involving 50 patients with superficial skin infections, after 2 weeks of treatment, 80% of the patients showed significant improvement in symptoms such as redness, swelling, and itching.
3. **Anti - Aging Cosmetic**: A cosmetic brand launched a serum containing 3% gallic acid. After a 4 - week trial with 100 volunteers, 70% of the volunteers reported an improvement in skin elasticity and a reduction in the appearance of fine lines.
