- Firstly, calcium carbonate factories can be categorized into two primary types natural and synthetic. Natural calcium carbonate factories extract limestone, marble, or chalk, all of which are rich in calcium carbonate, from the earth's crust. These materials are then processed through grinding and purification techniques to produce calcium carbonate powder. On the other hand, synthetic calcium carbonate factories create the compound through a chemical reaction between calcium oxide (quicklime) and carbon dioxide. This method is often used when a purer form of calcium carbonate is required.
“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
- In conclusion, titanium dioxide (TiO2) is a versatile white pigment with a range of applications in various industries. Its transparency, combined with its other properties such as opacity, brightness, and durability, makes it an attractive option for manufacturers seeking to improve the appearance and functionality of their products. With ongoing research and development, the future of transparent TiO2 looks promising, with new applications and markets emerging as consumers demand more aesthetically pleasing and high-performance products.
- Guangdong Huiyun Titanium Industry Co., Ltd is a Chinese manufacturer of rutile and other titanium products. The company's rutile production is primarily used for the manufacture of titanium dioxide, which is used in the production of pigments, ceramics, and coatings. Guangdong Huiyun Titanium Industry Co., Ltd is also a leading supplier of titanium sponge, which is used in the production of titanium metal and alloys.
There is some evidence that ingested titanium dioxide does not completely exit the body. A 2015 review of animal studies and a few human studies suggests titanium dioxide can get absorbed into the bloodstream and expose other organs to damage.
After conducting a review of all the relevant available scientific evidence, EFSA concluded that a concern for genotoxicity of TiO2 particles cannot be ruled out. Based on this concern, EFSA’s experts no longer consider titanium dioxide safe when used as a food additive. This means that an Acceptable Daily Intake (ADI ) cannot be established for E171.
- Titanium dioxide, also known as TiO2, is a versatile and widely used white pigment in various industries. As a key ingredient in paints, coatings, plastics, and even food and pharmaceutical products, titanium dioxide plays a crucial role in enhancing the appearance and performance of these products. With its excellent brightness, opacity, and UV-resistant properties, titanium dioxide is the go-to choice for manufacturers looking to achieve high-quality results.
