What is Titanium Dioxide (Nano Titanium Dioxide)?
Titanium Dioxide (TiO2) is an inorganic compound, commonly appearing as a white powder, and is widely used in cosmetics, paints, plastics, and food additives. Nano Titanium Dioxide refers to the nanoparticle form of titanium dioxide, which has a large surface area and unique physical and chemical properties, offering significant UV-blocking, antioxidant, and other characteristics. It is commonly used as a sunscreen agent and pigment in everyday products.

Functions and Applications of Titanium Dioxide (Nano Titanium Dioxide)

Sun Protection:
Nano Titanium Dioxide is commonly used in cosmetics and sunscreens. It effectively blocks UV radiation, protecting the skin from harmful rays, reducing sun damage and skin aging. Especially in cosmetics, nano titanium dioxide’s small particles form a lightweight protective layer without affecting the appearance of the skin.

Pigments and Coloring Agents:
Titanium Dioxide, due to its high refractive index and bright white color, is widely used as a pigment in paints, plastics, papers, and other products. It provides excellent coverage, making products appear bright white or more vibrant in color.

Antioxidant and Antibacterial Properties:
Nano Titanium Dioxide also possesses antioxidant properties, helping to reduce oxidation reactions in products. In some cases, it has mild antibacterial effects, which can help suppress bacterial growth and extend the shelf life of products.

Food Additive:
Nano Titanium Dioxide is used as a coloring agent (E171) in the food industry, especially in candies, gum, and other dessert products. It provides a bright white color, making the food more appealing to consumers.

Water Treatment and Environmental Protection:
Due to its catalytic properties, nano Titanium Dioxide is used in water treatment processes to degrade harmful substances through photocatalytic reactions. Additionally, it shows potential in cleaning air and water pollution.

Biomedical Applications:
The unique properties of nano Titanium Dioxide have made it a subject of exploration in the biomedical field, including its use as a drug carrier, antibacterial coating, and for wound healing applications.

Safety and Side Effects:
Nano Titanium Dioxide is widely used as an additive and ingredient, but its safety remains a concern. Most studies suggest that moderate use of nano Titanium Dioxide is generally safe, but long-term exposure and ingestion should be approached with caution, especially at high doses. Excessive exposure may trigger allergic reactions or skin irritation. Therefore, it is important to follow product usage guidelines and avoid overuse of products containing Titanium Dioxide.

Summary:
Titanium Dioxide (Nano Titanium Dioxide) is a widely used inorganic compound with multiple important functions, such as UV-blocking, sun protection, coloring, antioxidant properties, and more. It is commonly found in cosmetics, paints, foods, and medical products. While it is considered safe within reasonable usage limits, further research is needed regarding its potential long-term effects.
