One of the main benefits of using titanium dioxide in paint is its excellent hiding power. It allows the paint to effectively cover the surface, hiding imperfections underneath. This produces a smooth, even surface that gives walls a flawless appearance. Whether you're hiding stains or uneven patches, titanium dioxide-infused paint ensures a seamless and professional look.
- Whiteness is a critical factor in the performance of pigments, and TiO2 excels in this area. Its high refractive index allows it to scatter light more effectively, resulting in a brighter and more luminous color. This makes TiO2 particularly suitable for applications where maximum whiteness is required, such as in paints, plastics, and paper.
- The safety of food-grade titanium dioxide, or E171, lies in its ultrafine particle size. These particles are too small to be absorbed by the human body, passing through the digestive system without causing harm. Extensive research has been conducted to confirm this, with studies showing no evidence of genotoxicity or carcinogenicity. However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations

3. What is EFSA saying in its 2021 opinion on the safety of titanium dioxide as a food additive?
We’re most often exposed to E171 through the foods we ingest. We find E171 in many food products, like popsicles, ice cream, gum, and more. Another way we ingest E171 is through pharmaceutical drugs. Many pills and capsules contain E171 as an inactive ingredient.
Titanium Dioxide (TiO2) is a commonly used white pigment in paints due to its excellent whiteness, brightness, and weather resistance. It is also known for its ability to absorb ultraviolet light, which can help protect paint from fading and yellowing caused by sunlight. When TiO2 is used in paint, it is typically ground into a fine powder and then mixed with the other ingredients to create the final paint product. The amount of TiO2 used in paint can vary depending on the desired level of whiteness and opacity. In general, paints that are designed for outdoor use, such as exterior house paint, will contain higher levels of TiO2 than paints that are intended for indoor use. One of the main advantages of using TiO2 in paint is its ability to provide a durable and long-lasting finish. This is because TiO2 is very resistant to weathering and does not easily break down or fade when exposed to the elements. As a result, paints that contain TiO2 can provide excellent protection against the effects of sunlight, rain, and other environmental factors. Another advantage of TiO2 is its low cost compared to other pigments. This makes it an attractive option for manufacturers who want to produce high-quality paint at an affordable price This makes it an attractive option for manufacturers who want to produce high-quality paint at an affordable price This makes it an attractive option for manufacturers who want to produce high-quality paint at an affordable price This makes it an attractive option for manufacturers who want to produce high-quality paint at an affordable price
tio2 used in paint. However, the cost of TiO2 can vary depending on factors such as the quality of the raw material and the production process. In recent years, there has been some concern about the potential health risks associated with exposure to TiO2 dust. While studies have shown that TiO2 is generally considered safe for human contact, there is still some debate about the long-term effects of inhaling TiO2 particles. As a result, many manufacturers are now looking for alternative pigments that can provide similar levels of performance without the same health risks. Overall, Titanium Dioxide is a versatile and widely used pigment in the paint industry. Its ability to provide a durable and long-lasting finish, coupled with its low cost, make it an attractive option for manufacturers and consumers alike. However, as concerns about health risks continue to be studied, it is likely that we will see more research into alternative pigments that can provide similar benefits without the same potential health risks.
Lithopone 30% increases extruder performance and reduces processing costs, improves quality and is suitable for masterbatch for injection of Polyolefins, ABS, Polycarbonate, Polypropylene, Polyethylene, Polystyrene, single layer films, multi-layer films and for white, coloured and filled masterbatch. The combination of Lithopone 30 with TiO2 results in improved mechanical properties including higher elongation values and better impact resistance.
One of the most common worries about titanium dioxide is that it could be a cancer-causing agent. The link between cancer and titanium dioxide traces back to a 1985 study where rats were exposed to high levels of titanium dioxide for two years, causing lung cancer. However, not all experts are convinced by this study.
Titanium dioxide nanoparticles have also been found in human placentae and in infant meconium, indicating its ability to be transferred from mother to fetus.
Color, compared with standard samples
In 2017, the Scientific Committee on Consumer Safety (SCCS) warned that they should revise their recommendations if any new evidence emerges in the future related to the potentially harmful effects of TiO2NPs used in a sunscreen formulation or if they can penetrate the skin. In fact, our work could contribute to this matter because it evaluated the skin penetration of a particular kind of TiO2NPs. [8]
In addition to its aesthetic benefits, lithopone also offers practical advantages for leather suppliers. Due to its low cost and wide availability, lithopone is a cost-effective option for leather manufacturers looking to minimize production expenses without compromising on quality. Its stable chemical properties also make it easy to work with during the manufacturing process, resulting in a smooth and efficient production line.

For his part, Kaminski argues most of the studies have been in animals, and any effects found were minuscule. He and his team also contested some of the findings in a 2019 study that found no evidence of increased inflammation or changes in the GI tract.
Promotion of noncancerous tumors
In food products, E171 is not a singular ingredient; it’s always combined with other ingredients (e.g., proteins and fats) in the food product. Digesting food is a slow process for the body compared to drinking a beverage, which passes much faster through the body.
A steep decline in the prices of titanium dioxide was observed in the second half of 2022 as the erratic energy costs along with rising covid cases affected the market negatively. In addition to this, the decreased offtakes from paints and coating industries, weak economic growth, and strict restrictions imposed to deal with the resurgence of covid cases further aided the declining trajectory of titanium butoxide prices.
In a study published in the journal Toxicology, researchers examined the effects of exposing human colon cancer cell line (HTC116) titanium dioxide food additives in vitro. “In the absence of cytotoxicity, E171 was accumulated in the cells after 24 hours of exposure, increasing granularity and reactive oxygen species, inducing alterations in the molecular pattern of nucleic acids and lipids, and causing nuclei enlargement, DNA damage and tubulin depolymerization,” the scientists wrote. Researchers removed the additive from the culture, then examined the results 48 hours later. They found, “The removal of E171 was unable to revert the alterations found after 24 h of exposure in colon cells. In conclusion, exposure to E171 causes alterations that cannot be reverted after 48 h if E171 is removed from colon cells.”
What Is Titanium Dioxide?
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.
Other scientists, however, have called into question the experimental designs of such studies, citing inconsistent results specifically in studies used to test DNA damage.
There are many uses of titanium dioxide that we don't know about because they were made exempt from being on the package in 1977, said Faber, who added that nothing much has changed since – other than the FDA approving some other uses of the color additive, such as expanding the use of mica-based pearlescent pigments (prepared from titanium dioxide) as color additives in distilled spirits over recent years.
Developments in the paints & coatings industry and increase in plastic products are some of the major drivers of the global Lithopone market. It is used in paints and coating systems such as emulsion paints, as a partial replacement for Titanium Dioxide (TiO2) without loss of quality. The demand for white pigments in the plastic processing industry is projected to grow during the forecast period.
