There is some concern regarding skin and intestinal absorption of titanium dioxide nanoparticles, which are less than 100 nm in diameter.

Titanium dioxide manufacturer: Yuxing

Titanium dioxide has also been classified as a possible human carcinogen by the International Agency for Research on Cancer, which has caused concern about its use in food products. This classification, however, is currently based on limited evidence from animal studies that involved the inhalation of titanium dioxide particles that increased the risk of lung cancer.

Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.

Yesterday, some parts of the domestic rutile, anatase titanium dioxide new single price to maintain stability, titanium dioxide factory normal, more delivery of early orders, spot shipping pressure is small; And the buyer just needed to buy a few days ago. Downstream manufacturers are currently watching the latest execution price.The key factors affecting the current market price change1. Inventory: Low inventory of mainstream producers, mainly delivery of pre-contract orders, is expected today's spot inventory is still low, mainstream factories before the holiday spot tension.2. Mentality: the buyer has to prepare goods in advance, and the new order price is slightly less willing to purchase in bulk; Sellers due to the lack of inventory, manufacturers have no willingness to reduce the price of sales in the market of new orders just need to buy more.Trend: The load of titanium dioxide enterprises is stable, the willingness to ship at low prices is not strong, and the downstream buyer's early orders continue to digest, and the acceptance of the purchase before the holiday is acceptable. It is expected that the market of titanium dioxide just needs to be closed today, and it is concerned about the new execution price of the mainstream factory.

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 the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a 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.

The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 January 2009.  

In industrial settings, people can be exposed to titanium dioxide through inhalation. Inhalation exposure to titanium dioxide is exceedingly rare for most people.
