Core Functions and Applications
Daily Chemicals and Personal Care
Skin Care: Tannins can shrink pores and tighten skin, making them a common ingredient in acne treatment products.
Sunscreen and Whitening: It absorbs ultraviolet rays and inhibits the activity of tyrosinase, thus being used in sunscreen and whitening products.
Anti-aging and Moisturizing: By scavenging free radicals and inhibiting the activity of elastase and hyaluronidase, tannins help delay skin aging and maintain skin elasticity and moisture.
Food and Health Products
In the food industry, tannins can be used as a natural antioxidant and clarifying agent for clarifying and stabilizing the color of fruit wines and juices. They can also be used to develop foods with specific health benefits.
Pharmaceuticals and Health
Broad-spectrum Antibacterial and Anti-inflammatory: Tannins inhibit the growth of various bacteria and viruses. Studies have shown that they have inhibitory effects on various pathogenic bacteria such as Staphylococcus aureus and Escherichia coli.
Functional Activity: Modern research has also revealed its potential in anti-oxidation and blood pressure and lipid regulation, providing a basis for the development of functional foods and pharmaceuticals.
Traditional Industries
Leather Tanning: A classic application, tannic acid can cross-link with soluble proteins in raw hides, causing them to coagulate and stabilize, transforming easily perishable raw hides into supple, durable, and less prone to deterioration leather.
Metal Surface Treatment: Utilizing its ability to complex with metal ions, tannic acid can form a dense protective film on metal surfaces, effectively applied to the passivation treatment of metals and alloys such as zinc, copper, and iron, playing a role in rust prevention and enhancing corrosion resistance.
