2. Cosmetics With its UV-filtering properties, anatase TiO2 is a popular ingredient in sunscreens and cosmetic formulations. Its ability to scatter UV radiation effectively protects the skin from harmful sun exposure, contributing to the increasing popularity of natural and mineral makeup products.

Why does the exposure route matter, and what's the risk? 

It should also be considered that due to the low pH in the stomach, the increased dissolution of the TiO₂ particles may increase its bioavailability and may facilitate the entry of titanium ions into the blood circulation. Despite the relatively large consumption of TiO₂ as a food additive, no studies on the effect of pH on its absorption and bioavailability have been found in the literature. This can be attributed to a general belief that TiO₂is completely insoluble. However, this is not completely true, as TiO₂ particles show a certain degree of solubility.

Despite its many advantages, the production of lithopone is not without its challenges. The raw materials used to make lithopone, particularly zinc sulfide, can be expensive and difficult to source. In addition, the production process itself can be complex and energy-intensive, requiring specialized equipment and skilled workers to operate. As a result, lithopone manufacturers must carefully manage their operations to ensure they remain competitive in the market.

Mars Wrigley, the company that makes Skittles, is being sued by a California man who claims the candy contains a known toxin that poses such a serious health risk that Skittles are unfit for human consumption.

The FDA and certain others say titanium dioxide is safe to use in foods and personal care products. The FDA provides strict guidelines on how much can be used in food. The limit is very small: no more than 1% titanium dioxide.

Titanium dioxide holds exceptional significance as a white pigment due to its superior scattering capabilities, remarkable chemical stability, and non-toxic nature. Among all white pigments, it surpasses others in terms of its ability to scatter light effectively. Consequently, titanium dioxide stands as the most significant inorganic pigment, accounting for the highest quantity in usage. The majority part of the global production of ilmenite and rutile is dedicated to the production of TiO2 pigments. The remaining portion is utilized for the manufacturing of titanium metal and in the production of welding electrodes.

TiO₂ possesses different qualities depending on whether it is produced as a pigment or a nanomaterial. Both forms are tasteless, odourless and insoluble.

There is some evidence that ingested titanium dioxide does not completely exit the body. A 2015 review of animal studies and a few human studies suggests titanium dioxide can get absorbed into the bloodstream and expose other organs to damage.

Variations of titanium dioxide are added to enhance the whiteness of paint, plastics, and paper products, though these variations differ from the food-grade ones for things we eat (1Trusted Source, 2Trusted Source).

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Scientists analyzed research that examined how titanium dioxide nanoparticles interact with the brain for a 2015 review published in Nanoscale Research Letters. The researchers wrote: “Once the TiO2 NPs are translocated into the central nervous system through [certain] pathways, they may accumulate in the brain regions. For their slow elimination rates, those NPs could remain in the brain zones for a long period, and the Ti contents would gradually increase with repeated exposure.” After reviewing dozens of studies, the scientists concluded: “Long-term or chronic exposure to TiO2 nanoparticles could potentially lead to the gradually increased Ti contents in the brain, which may eventually induce impairments on the neurons and glial cells and lead to CNS dysfunction as a consequence.”

Titanium dioxide morning tips
1 Rutile type titanium dioxide
As of the close of last Friday, the average price of the sulfuric acid rutile titanium dioxide market assessment is 15683 yuan/ton, the domestic market mainstream negotiation reference 15200-16200 yuan/ton, the mainstream factory in hand orders are okay, coupled with the upstream raw materials expected to be strong, the new single offer to maintain a strong state, the market low price supply reduction.
According to the feedback of manufacturers, the recent mainstream factory new single price, the overall market transaction focus has moved up. On the demand side, the terminal in August is still the off-season, many downstream last month to replenish just need inventory, the current batch purchase intention is limited, the market turnover is low. From the supply side, the mainstream manufacturers still have production reduction or maintenance adjustment inventory in the off-season, and the supply side output is low. Some plastics and papermaking related downstream feedback some models have high prices. Recent titanium dioxide raw material price upward support has been enhanced, comprehensive market factors, the current titanium dioxide market into the stable price state after rising.
2 Anatase titanium dioxide
As of the close of last Friday, the average price of the domestic anatene titanium dioxide market was estimated at 13,000 yuan/ton, and the mainstream reference range for negotiation was mostly centered on 12,500-13,500 yuan/ton. The actual direct selling link price is still more reference in 13,000 yuan/ton. Some lower-priced producers offer even lower prices. On the demand side, because the current price is still relatively low, some downstream bargain purchasing. On the supply side, some manufacturers operate at low load or have maintenance plans. The comprehensive market supply and demand situation and the trend of raw material prices rise, the current market actual transaction price is stable and strong, some manufacturers of titanium diox

When manufacturers add titanium dioxide to foods and other ingestible products, it’s typically referred to as E171, which relates to food-grade purity.

Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.
