There's also evidence that inhaling titanium dioxide particles can be dangerous. That's mainly a concern for industrial workers. In places where it's produced, or where it's used to make other products, workers can breathe it in as a dust. The Occupational Health and Safety Administration has exposure standards manufacturers must meet.

What's the Verdict?

Moreover, lithopone suppliers are expanding their product lines to offer variations of the pigment that meet specific market needs. Some suppliers provide specialized grades of lithopone that are tailored for particular applications, such as high gloss paints or specialty coatings. By offering these tailored solutions, suppliers can help paint manufacturers enhance the performance characteristics of their products, thus gaining a competitive edge in the market.

The second quarter of 2022 saw mixed market sentiments for titanium dioxide prices. Due to demands, constrained supply and ineffective production capacity brought on by the stretched supply chain, labour shortage, and high energy prices, the production of the chemical increased in Q2 of 2022. Moreover, the US Federal Reserve's tight monetary policy and high interest rates worsened the domestic trade picture, which at quarter's conclusion supported titanium dioxide's unfavourable market views.

Stability and darkening

Other food manufacturers use titanium dioxide to absorb water and keep moisture from clumping or degrading, Paul Westerhoff, PhD, an environmental engineer at Arizona State University who researches the biological and cellular effects of titanium dioxide, told Health.

3. What is EFSA saying in its 2021 opinion on the safety of titanium dioxide as a food additive?

Hebei Caiqing Material Technology Co., Ltd. was established in 2005 and has been at the forefront of chemical product research and development. Focusing on the field of titanium dioxide, the company has played a vital role in meeting global demand, providing personalized customization services to global customers. With the continuous expansion of the titanium dioxide market, Hebei Caiqing Material Technology Co., Ltd. is ready to meet the industry's growing demand in terms of production and service.

According to the feedback of manufacturers, the recent mainstream factory new single price, the market as a whole into the center of gravity. On the demand side, the terminal in August is still the off-season, many downstream still have inventory use, the current batch purchase intention is limited, and the market turnover is low. Some plastics and papermaking related downstream feedback part of the signal price is high. Recent titanium dioxide raw material price shock is strong, titanium dioxide price upward support has been enhanced, comprehensive market factors, the current titanium dioxide market into the stable price state after rising.

Less frequently, we ingest E171 through liquids such as salad dressing, dairy products, and some artificially colored drinks. However, since E171 is insoluble, manufacturers must use other stabilizers to keep E171 suspended in liquids as an emulsion; otherwise, it will settle to the bottom. 

Lithopone 30% is a perfect alternative to titanium dioxide in all natural and synthetic pigmented elastomers, as it is non-abrasive and extremely acid resistant. 

In conclusion, lithopone is an important white pigment that is used in a variety of industries around the world. With 30% of the world's lithopone factories located in China, the country has become a major player in the global lithopone market. Chinese manufacturers are able to produce high-quality lithopone at a competitive price, making it an attractive option for companies looking to reduce their production costs. Despite the challenges of production, China's lithium industry continues to thrive and innovate, ensuring a stable and reliable supply of this essential pigment for years to come.

Here, NaOH or NH3 · H2O is used as a precipitant or pH regulator to react with FeSO4 to form ferrous hydroxide precipitation; Air is used as oxidant; The iron sheet reacts with sulfuric acid produced during the oxidative hydrolysis of FeSO4 to provide ferrous ions required in the reaction system and maintain the pH value of the solution. The alkali consumption of acid method is less and the particles are easy to wash. The relative rates of seed preparation and crystal growth determine the particle size, particle size distribution and particle morphology of iron yellow particles.

Food quality

EFSA has updated its safety assessment of the food additive titanium dioxide (E 171), following a request by the European Commission in March 2020. 

It’s true that titanium dioxide does not rank as high for UVA protection as zinc oxide, it ends up being a small difference (think about it like being 10 years old versus 10 years and 3 months old). This is not easily understood in terms of other factors affecting how sunscreen actives perform (such as the base formula), so many, including some dermatologists, assume that zinc oxide is superior to titanium dioxide for UVA protection. When carefully formulated, titanium dioxide provides excellent UVA protection. Its UVA protection peak is lower than that of zinc oxide, but both continue to provide protection throughout the UVA range for the same amount of time.
