Another advantage of tek screws is their ease of use. Unlike traditional screws that require a pilot hole to be drilled before installation, tek screws can be driven directly into the material using a power drill or screwdriver. This saves time and effort, making tek screws a popular choice for professionals and DIY enthusiasts alike
- In conclusion, China's billion-ton TiO2 industry is a microcosm of the country's economic strength and industrial sophistication. It not only underscores China's manufacturing might but also highlights its ability to adapt and innovate in the face of challenges. As the world continues to grapple with the balance between economic progress and environmental sustainability, China's TiO2 sector will undoubtedly play a pivotal role in shaping the future of this critical industry.
In a 2020 study published in the Journal of Trace Elements in Medicine and Biology, researchers conducted an in vitro experiment to analyze the effects of TiO2 nanoparticles on a human neuroblastoma (SH-SY5Y) cell line. The scientists evaluated “reactive oxygen species (ROS) generation, apoptosis, cellular antioxidant response, endoplasmic reticulum stress and autophagy.” The results showed that exposure to the nanoparticles “induced ROS generation in a dose dependent manner, with values reaching up to 10 fold those of controls. Nrf2 nuclear localization and autophagy also increased in a dose dependent manner. Apoptosis increased by 4- to 10-fold compared to the control group, depending on the dose employed.”

Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”.

2. Relative density: 4.136 to 4.39 g/mL.
3. Photocatalysis The photocatalytic properties of anatase make it valuable for environmental applications such as air and water purification. Manufacturers are exploring its potential in self-cleaning surfaces and photocatalytic reactors, which can degrade pollutants under UV light.
In 2019, EFSA published a statement on the review of the risk related to the exposure to food additive titanium dioxide (E171) performed by the French Agency for Food, Environment and Occupational Health Safety (ANSES). In its statement, EFSA highlighted that the ANSES opinion reiterated the uncertainties and data gaps previously identified by EFSA and did not present findings that invalidated the Authority’s previous conclusions on the safety of titanium dioxide.

Lithopone powder, chemically known as zinc sulfide/zinc oxide, is a white pigment produced through a precipitation process involving zinc sulfate and barium sulfate. It is characterized by its high refractive index, excellent hiding power, and resistance to UV radiation, making it an ideal choice for various applications.
