- Anatase TiO2 with 99.6% purity exhibits excellent physical and chemical properties. It has a high refractive index, which contributes to its high opacity and excellent hiding power. The material is also highly resistant to UV light, making it suitable for use in outdoor applications. Chemically, it is stable under normal conditions and does not react with most acids or bases.
According to the EFSA's Expert Panel on Food Additives and Flavorings 2021 opinion regarding titanium dioxide, it could not rule out a concern for genotoxicity from ingestion of the material based on a perceived gap in data on this risk, which serves as the basis for current ban, said a March report on the decision.
When we purchase lithopone, we must pay attention to its ratio. This can be seen to some extent from the appearance. Basically, we can see that good products are very delicate. , and the color is also very uniform, a kind of shiny white, while inferior lithopone has uneven particles and wrong luster.
Another important application of titanium dioxide is in the production of sunscreen and other skincare products. Titanium dioxide is a key ingredient in many sunscreens due to its ability to reflect and scatter ultraviolet (UV) radiation, providing protection against harmful UV rays. Manufacturers of titanium dioxide for sunscreen products often use special coatings and surface treatments to enhance its UV-blocking properties.
What titanium dioxide is really emblematic of ... is the failure of FDA to look back at these old decisions and ask whether its decisions that were made in this case ... 56 years ago (in the 1966 approval) still hold up, he said.
Titanium dioxide prices in the Asian market skyrocketed due to high demand and limited stock availability. Prices in the Chinese market surged significantly, reaching 2875 USD /MT at the end of March, well above the USD 2015/MT level in January 2021.
- In conclusion, titanium dioxide is an indispensable additive for plastic factories due to its multifaceted benefits. From protecting against UV damage to enhancing physical strength and improving aesthetic qualities, TiO2 plays a critical role in producing high-quality plastic products that meet the demands of modern industry and consumer expectations. As research continues to explore new applications and improvements in this field, the significance of titanium dioxide in plastic manufacturing is poised to grow even further.

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.
While Skittles don't include white in their line-up, Dr. Johnson-Arbor theorizes that titanium dioxide is used to help contain all the other beautiful colors.
Let’s break the risk down further.
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.
Animal studies show exposure to titanium dioxide is linked to immunotoxicity, inflammation and neurotoxicity.
It’s also used in food products to provide a white color. Candies, cakes and creamers are examples of foods that may contain titanium dioxide for its color enhancing and bleaching properties.
How is titanium dioxide extracted?
lithopone supplier 30%, in any type of rubber, not only reduces the cost of partial substitution of TiO2 but also increases industrial production and improves the durability and the thermal and mechanical resistance of the finished product.
BaSO4+4CO→BaS+4CO2
The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.

“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
