Our scientific experts applied for the first time the 2018 EFSA Scientific Committee Guidance on Nanotechnology to the safety assessment of food additives. Titanium dioxide E 171 contains at most 50% of particles in the nano range (i.e. less than 100 nanometres) to which consumers may be exposed.
- The journey of TIO2 begins with mining raw materials, primarily ilmenite, rutile, and anatase minerals, which are then processed through various methods including the chloride process or the sulfate process. The chosen procedure significantly impacts the final characteristics of the TIO2 pigment, such as its particle size, distribution, and crystalline structure, which in turn affect its optical properties.
How can food businesses comply with this Regulation?
Digestive System Exposure

Zinc Oxide
The committee could not finalize the assessment of some other flavoring agents, requiring further information. JECFA highlighted the importance of receiving complete data submissions from the sponsors for conducting the safety evaluation.
Why does the exposure route matter, and what's the risk?

best price titanium dioxide manufacturer. A manufacturer with a large production capacity can quickly fulfill large orders, while shorter lead times ensure timely delivery. This is particularly important for businesses with tight production schedules or those in need of titanium dioxide for time-sensitive projects.

Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified, and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.

Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.
Furthermore, this packaging has been shown to have both antibacterial and photocatalytic activity, the latter of which reduces ultraviolet (UV) exposure (5Trusted Source, 6).
Titanium dioxide is not unfamiliar to those involved in the chemical industry. Titanium dioxide is currently the highest-quality white pigment in the world, mainly used in plastics, coatings, paper, ink, chemical fiber, cosmetics and other industries. So what are the top five brands of titanium dioxide in China with good reputation? Let’s take a look.
Then, there’s ultrafine-grade, also known as nanoscale titanium dioxide. This is used for its ability to scatter lightly as an ultra-fine powder. This gives it the ability to lightly absorb into the skin while providing a bit of transparency. Below, we’ll go more into the cosmetic uses of these two forms of titanium dioxide.
This precipitate is not suitable for a pigment until it is filtered, dried, crushed, heated to a high temperature and quenched in cold water. The second heating in a muffle furnace at 725 °C produces crystals of the right optical size.
Magnesium occurs in seawater and in ores such as dolomite (CaCO 3 MgCO 3), magnesite (MgCO 3), and carnallite (MgCl 2 KCl 6H 2O).
