hard rock drill bit. In construction, they facilitate the creation of foundations for towering skyscrapers and complex underground infrastructure. In mining, they aid in extracting valuable minerals from the earth's depths, contributing significantly to global economic growth.
It's crucial to ensure that the drill is adequately lubricated to prevent overheating and prolong the bit's lifespan It's crucial to ensure that the drill is adequately lubricated to prevent overheating and prolong the bit's lifespan34mm drill bit. Additionally, always use a pilot hole for accuracy and to reduce the risk of the bit wandering or breaking.
The FDA first approved the use of titanium dioxide in food in 1966, following its 1960 removal (along with the removal of other color additives) from the agency's original Generally Recognized as Safe list. In 1977, titanium dioxide joined the list of color additives that are exempt from certification, which means titanium dioxide doesn't have to be listed on the packaging of every product it's used in, Faber noted.
As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.

Moreover, titanium dioxide is also used in rubber formulations to improve the processing and curing properties of rubber compounds. It acts as a catalyst in the vulcanization process, speeding up the cross-linking of rubber molecules and enhancing the overall performance of the final product. This results in rubber products that are stronger, more flexible, and better suited for a wide range of applications.
Above 20%, it is recommended to replace 1 kg TiO2 with 1.3 kg of Lithopone 30%.
CAS registration number: 1345-05-7
Due to its light-scattering properties, small amounts of titanium dioxide are added to certain foods to enhance their white color or opacity (1Trusted Source, 3Trusted Source).
A 2022 review on past studies of titanium dioxide and rat lung cancer, for instance, said the original study was under extreme conditions and its effects were not replicated in other animal species. Additionally, the review concluded that the few studies which did directly focus on titanium dioxide's impact on humans did not end up showing any increased cancer risk.
Because of the uncertainty of the impacts of nanoparticles, Made Safe exercises the precautionary principle, meaning we avoid nanoparticles until more extensive scientific testing proves their safety.
