- In addition to coated papers, titanium dioxide is also used in the production of specialty papers, such as those used for labels, packaging, and security documents. In these applications, titanium dioxide is added to the paper pulp to increase the opacity and brightness of the paper. This helps to create a more professional and appealing appearance for the final product, as well as providing enhanced security features through the use of fluorescent or UV-reactive titanium dioxide particles

- In conclusion, lithopone emerges as a game-changing additive for the rubber industry. Its ability to provide outstanding color, protect against UV degradation, strengthen rubber compounds, ensure safety, and streamline the manufacturing process makes it invaluable. As research continues and new applications arise, lithopone promises to maintain its position at the forefront of innovation in rubber technology.
Bluescope Steel now specifically mention sunscreen & titanium dioxide use in their warranty so they no longer have to pay out for the damage caused by a little bit of transferred sunscreen residue.

- China is known for being one of the largest producers and consumers of titanium dioxide (TiO2) in the world. TiO2 is a white pigment that is commonly used in paints and inks due to its excellent opacity, brightness, and UV protection properties.
The integrity of surface skin cells was evaluated with and without solar simulated irradiation. The integrity of the stratum corneum was significantly lower in individuals treated with P25TiO2NPs under the light in comparison to the ones that received the functionalized nanoparticles. Cell membrane suffering is evident (Fig. 9), and it is in accordance with the ROS levels and macromolecule oxidation found in vitro for the irradiated P25TiO2NPs. Disruption of the superficial skin layer was observed in all animals treated with no functionalized nanoparticles, under irradiation. This data expands the findings by the group of Professors Fubini and Fenoglio, who showed that P25TiO2NPs could impact the lipid structure at the top few microns of the stratum corneum [55]. Control skin under irradiation and without any topic formulation did not show changes in cell structure.
- China has established itself as a global hub for the production of lithopone, with a significant number of manufacturers catering to various industries. Among these, several companies have emerged as leaders in the production of lithopone B311, a widely used pigment in the coatings, plastics, and rubber industries. This article aims to provide an overview of the top Chinese manufacturers of lithopone B311, their key features, production capabilities, and market presence.

The production of ROS was studied on white blood cells as a model to screen the effect on eukaryotic cells after being exposed to samples and solar simulated irradiation (according to the level of penetration under the skin). For that purpose, the leukocytes were separated from anticoagulated fresh blood using the Ficoll-Hypaque reactive in a well-known technique [33]. Then, 50 μL of suspensions of P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL), vitaminB2@P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL) and vitamin B2 (0.2 mg/mL and 0.02 mg/mL) were prepared and mixed with 50 μL of white blood cells suspension. A solution of 3% H2O2 was used as positive control and PBS as negative control. Then, the samples were irradiated using the LED panel for 3 and 6 h to simulate the light penetration into the skin. Also, a set of samples was kept in the dark as control. Finally, the ROS were detected through the colorimetric assay employing the nitroblue tetrazolium salt (NBT salt) and the absorbance at 650 nm was measured. The experiment was reproduced twice; the standard deviation was calculated and p-value < 0.05 were considered significant.

For the Year 2020
Below 10% substitution, 1 kg of TiO2 should be replaced by 1 kg of Lithopone 30%.
EINECS accession number: 215-715-5

Stability and darkening
TiO2 absorbs UV light. This property makes it appear bright white under light, unlike other white materials that can look slightly yellow.

The surge in demand for interior and exterior paints and use of plastic across various end-use industries drive the global Lithopone market. Lithopone white pigment is used in paints and coating systems that find applications in residential and industrial landscapes. Hence, as the construction & building sector flourishes, the demand for building and architectural materials such as paints and coatings will increase. This trend is conducive for the Lithopone market growth. In addition, white plastic materials are increasingly being used in consumer products. Developments in plastic forming technology is anticipated to indirectly boost plastic production, thus, increasing the demand for white pigments during the forecast period.
In a statement sent to USA TODAY on Sunday, Justin Comes, vice president of research and development for Skittles maker Mars Wrigley North America, said the company couldn't comment on pending litigation – but that its use of titanium dioxide and all Mars Wrigley ingredients are safe and manufactured in compliance with strict quality and safety requirements established by food safety regulators, including the FDA.
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.
