Titanium dioxide, or TiO2, will be listed on product labels, but companies are not required to list ingredient size or structure. When it is used in sunscreens to block UV light, titanium dioxide is considered an active ingredient, which means the concentration must also be listed.

This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO₄. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.^[1]

Lithopone powder is a versatile and indispensable ingredient in various industries, contributing to the quality, durability, and aesthetic appeal of numerous products. From paints and coatings to plastics and ceramics, its high opacity, UV resistance, and cost-effectiveness make it a preferred choice for manufacturers worldwide. As advancements in manufacturing and formulation techniques continue, lithopone powder is expected to remain a key player in the global pigment market, fulfilling diverse needs and driving innovation across industries.

Titanium dioxide as used in sunscreens is commonly modified with other ingredients to ensure efficacy and stability. Examples of what are known as surface modifier ingredients used for titanium dioxide include stearic acid, isostearic acid, polyhydroxystearic acid, and dimethicone/methicone copolymer.

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

Titanium dioxide is an inert earth mineral used as a thickening, opacifying, and sunscreen ingredient in cosmetics. It protects skin from UVA and UVB radiation and is considered non-risky in terms of of skin sensitivity. Because it is gentle, titanium dioxide is a great sunscreen active for sensitive, redness-prone skin. It’s great for use around the eyes, as it is highly unlikely to cause stinging.

Other research suggests that E171 could cause harm; however, those research processes did not consider how people are typically exposed to E171. Research that adds E171 to drinking water, utilizes direct injections, or gives research animals E171 through a feeding apparatus is not replicating typical human exposure. 

The updated evaluation revises the outcome of EFSA’s previous assessment published in 2016, which highlighted the need for more research to fill data gaps.  

Food safety experts in the European Union (EU) have recently updated their safety assessment of TiO₂ as a food additive. In Europe, TiO₂ is referred to as E171, in accordance with European labelling requirements for food additives. The EU expert panel took into account toxicity studies of TiO₂ nanoparticles, which to this point had not been considered relevant to the safety assessment of TiO₂ as a food additive.  

Lithopone B301, Lithopone B311 powder, C.I. Pigment White 5, is a mixture of inorganic compounds, widely utilized as a white pigment. It is composed of a mixture of barium sulfate and zinc sulfide. These insoluble compounds blend well with organic compounds and confer opacity. Lithopone B301, Lithopone B311 powder is famous for the cheap production costs, greater coverage. Related white pigments include titanium dioxide, zinc oxide (zinc white), and zinc sulfide

Both P25TiO₂NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.

For the Year 2020

The US and Canada, however, approve the use of titanium dioxide as a food additive. Canada's recent review of titanium dioxide reconfirmed its safety and pointed out that many of the toxicity studies the EU reviewed were not relevant to the safety of titanium dioxide as a food ingredient, and that the ban is based on an abundance of caution and uncertainty.

Well asides from making you re-think that M & M addiction (chocolate coated in Titanium Dioxide…..anyone?!)

‌If you're curious about whether something you’re eating contains titanium dioxide, you can check the ingredients list. But know that the FDA doesn’t require food makers to use its chemical name on an ingredients list. Instead, it could be listed as:

Price increases of 139-174 USD /MT were seen in Q3 by western suppliers in a tight and buoyant market that faced multiple persistent pulls on supply, including an ongoing lack of Chinese export competitiveness. Furthermore, container constraints hampered its delivery to the rest of the world.
