- The photocatalytic properties of rutile titanium dioxide make it an important material in environmental applications
titanium oxide rutile. When exposed to ultraviolet light, it can catalyze reactions that break down organic pollutants into carbon dioxide and water, thereby helping to purify air and water. This feature is utilized in self-cleaning surfaces, air purification systems, and even in the development of certain antimicrobial products.
- After the mixing, the concrete is poured into molds or forms, where it undergoes a curing process
Overall, the Food Directorate's comprehensive review of the available science of TiO2 as a food additive showed:
Is titanium dioxide dangerous? Has it been linked to any health issues?
Titanium Dioxide Raw Material Tio2 Powder
Total zinc and barium sulphate
10max - The production of rutile and anatase titanium dioxide involves several steps, including the extraction of titanium ore, purification, and finally, the conversion of the ore into the desired crystalline form
For years scientists have raised concerns about the potential toxicity of titanium dioxide.
Titanium dioxide can amplify and brighten white opacity because of its exceptional light-scattering properties. In food and drugs, these properties help to define colors clearly and can prevent products from UV degradation.

FAQ – EFSA 2021 safety assessment of titanium dioxide (E171)
Both calcium carbonate and titanium dioxide play crucial roles in various industries, but they are used for different purposes. Calcium carbonate is primarily used as a filler and pigment, while titanium dioxide is used as a whitening agent and pigment. Additionally, titanium dioxide is more expensive to produce than calcium carbonate due to its synthetic nature and complex manufacturing process.
Additionally, the construction sector benefits from MBR9668’s properties. Architectural coatings that incorporate this advanced titanium dioxide ensure enhanced resistance to UV degradation, meaning buildings can maintain their visual appeal and structural integrity longer than those using inferior materials. The superior performance against fungal and algal growth in exterior paints is another advantage, making MBR9668 an attractive option for developers concerned about the maintenance and lifespan of their structures.

That being said, most experts tell us that these potential health risks shouldn’t trouble us, because titanium dioxide has been used in the market for decades, and no adverse reactions have been reported by users. The bottom line is that when used correctly, titanium dioxide should be a safe ingredient that’s safe for all skin types, every day
What’s recently changed with titanium dioxide and regulations?
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.

According to CCM, many enterprises, which belong to the top exporting producers of TiO2 in China, will speed up their efforts to go public. Reasons are the strong rebound of the TiO2 market in China as well as the positive view on 2017.

From studies deemed relevant, the experts found that titanium dioxide as a food additive is poorly absorbed by the gastrointestinal tract of mice and rats, with no adverse effects observed in short-term studies in rodents receiving titanium dioxide in their diets. No observed adverse effect levels (NOAELs) of 15,000 milligrams per kilogram of bodyweight (mg/kg BW) per day and 5,000 mg/kg BW per day—the highest doses tested—were established for mice and rats, respectively.
