Potential hazards of oral exposure to TiO2 NPs
We apply titanium dioxide to our skin through sunscreens, makeup, lip balms, nail polish, and other cosmetic products.
- In the world of pigments, titanium dioxide stands tall as a favorite material for its ability to provide brilliant whiteness and exceptional opacity. Its refractive index is high, making it ideal for achieving that pure, lustrous look in paints and coatings. But its capabilities don’t end there; titanium dioxide is also prized for its stability and resistance to discoloration, ensuring longevity in artistic creations and protective layers.
At the present JECFA meeting, the committee considered additional toxicological studies relevant to the safety assessment of the chemical that investigated its toxicokinetics, acute toxicity, short-term toxicity, long-term toxicity and carcinogenicity, genotoxicity, and reproductive and developmental toxicity, as well as special studies addressing its short-term initiation/promotion potential for colon cancer. The experts acknowledged that a large number of toxicological studies have been conducted using test materials, including nanoparticles, having size distributions and physico-chemical properties not comparable to real-world uses of titanium dioxide as a food additive. The studies on non-representative materials were evaluated by JECFA, but the committee concluded that such studies are not relevant to the safety assessment of the additive.
- In the sulfate process, the ore is first crushed and then heated with sulfuric acid. This reaction produces titanyl sulfate, which is subsequently treated with water to form titanium dioxide. The resulting precipitate is filtered, washed, dried, and calcined to produce the final product. One of the drawbacks of this method is the large amount of waste acid generated, which requires careful disposal to minimize environmental impact.

- Cosmetics manufacturers utilize titanium dioxide for its ability to provide sun protection and enhance the appearance of skincare products. As a physical sunscreen, TiO2 effectively blocks harmful UV rays, preventing skin damage and reducing the risk of skin cancer. Additionally, its natural white color adds luminosity to makeup and other beauty products, making them more appealing to consumers.
- THR-6666 is a specialty rutile titanium dioxide known for its high temperature resistance and lightfastness. It is commonly used in applications where exposure to extreme heat and light is a concern, such as automotive coatings, high-temperature paints, and industrial coatings. THR-6666 offers excellent thermal stability and color retention, making it a reliable choice for demanding environments.
- TiO2 particles of the right size scatter visible light, having wavelength λ ≈ 380 - 700 nm, effectively because TiO2 has a high refractive index
- China is one of the largest producers of titanium oxide in the world, and the industry plays a significant role in the country's economy. Titanium oxide, also known as titanium dioxide, is a naturally occurring oxide of titanium with the chemical formula TiO2. It is commonly used as a pigment in a wide range of products, including paints, coatings, plastics, and cosmetics.
- In the vast and dynamic landscape of global industry, China has carved out a niche for itself as a leader in manufacturing and production. One such example is found within the realm of lithopone, a vital component used extensively in paints, plastics, and other industrial applications. The quality of Chinese lithopone, often underscored by its consistency and reliability, is a reflection of the nation's commitment to innovation and sustainability.
- Honey buns are a popular snack enjoyed by people of all ages. These delicious pastries are typically made with a combination of flour, sugar, butter, eggs, and honey. However, the ingredients list for honey buns can vary depending on the manufacturer. One ingredient that is sometimes included in honey bun recipes is titanium dioxide.

Genotoxicity Assessment
- Titanium dioxide (TiO2), a naturally occurring mineral compound, has found its significant application in various industries, prominently in oil factories. This white, odorless, and highly refractive substance is well-known for its exceptional light-scattering properties, making it an essential ingredient in numerous products. In the oil industry, titanium dioxide's role goes beyond mere aesthetics; it plays a crucial part in enhancing efficiency and product quality.
- The global precipitated barium sulfate market is flourishing due to its versatile applications in various industries. This article aims to shed light on the key suppliers dominating this market. These suppliers have established a strong reputation for providing high-quality products and exceptional customer service.
Titanium dioxide nanoparticles may accumulate and cause DNA damage
Solids were stable and did not show visible signs or changes in their spectra after being kept at room temperature for over 60 days. The absorbance at the maximum absorbance wavelength remained unmodified.
