The updated evaluation revises the outcome of EFSA’s previous assessment published in 2016, which highlighted the need for more research to fill data gaps.
Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.
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.”
Thanks to its rheological and optical properties, Lithopone offers both technical and economic advantages wherever organic and inorganic binder systems require a relatively high pigmentation for specific applications.

Studies have been carried out with both emulsion paints and powder paints, both with clear results on how the use of Lithopone 30% reduces the appearance of algae in the paint once it has been applied (see photos).

On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):
“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.”
The agency makes this exception for several approved color additives.
The disadvantage of Titanium Dioxide is that it's not cosmetically elegant, meaning it's a white, unspreadable mess. Sunscreens containing Titanium Dioxide are often hard to spread on the skin and they leave a disturbing whitish tint. The cosmetic industry is, of course, really trying to solve this problem and the best solution so far is using nanoparticles. The itsy-bitsy Nano-sized particles improve both spreadability and reduce the whitish tint a lot, but unfortunately, it also introduces new health concerns.
Jinan Yuxing Rutile Titanium Dioxide R-818 is a rutile titanium dioxide pigment coated with inorganic silicon aluminum and organic surface treatment. It has good gloss and hiding power, high weather resistance and good dispersibility.
Scope of application: plastic steel profiles, coil paint, powder coatings, rubber, masterbatch, etc.
Titanium dioxide is used in a wide range of food products and consumer goods – from candy to sunscreen and house paint. The U.S. Food and Drug Administration maintains that the regulated use of titanium dioxide, specifically as a color additive in food, is safe under some restrictions.
The construction sector, which accounts for a significant portion of China's GDP, is one of the largest consumers of titanium dioxide, using it extensively in paints and coatings The construction sector, which accounts for a significant portion of China's GDP, is one of the largest consumers of titanium dioxide, using it extensively in paints and coatingschina talc titanium dioxide. Similarly, the country's booming cosmetics and pharmaceutical industries have fueled demand for talc, which is used as a filler, absorbent, and lubricant in many products.
Rutile Titanium Dioxide MBR9668 Coating Supplier Enhancing Performance and Durability

titanium dioxide rutile tio2 emulsion latex paints manufacturer. Manufacturers utilize high-speed mixing equipment to evenly distribute the pigment particles throughout the emulsion, preventing agglomeration and ensuring consistent product quality. The concentration of rutile TiO2 used depends on the desired level of hiding power and the specific end-use requirements of the paint.In the automotive industry, for example, MBR9668 is used in primers and finish coats to provide superior color retention and gloss. With durability being a key concern for automotive manufacturers, utilizing rutile titanium dioxide in coatings enhances the longevity of the vehicle's exterior finishes, ensuring that they remain vibrant and effective for years under various conditions.
While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.
