Different dermal cell types have been reported to differ in their sensitivity to nano-sized TiO2 . Kiss et al. exposed human keratinocytes (HaCaT), human dermal fibroblast cells, sebaceous gland cells (SZ95) and primary human melanocytes to 9 nm-sized TiO2 particles at concentrations from 0.15 to 15 μg/cm2 for up to 4 days. The particles were detected in the cytoplasm and perinuclear region in fibroblasts and melanocytes, but not in kerati-nocytes or sebaceous cells. The uptake was associated with an increase in the intracellular Ca2+ concentration. A dose- and time-dependent decrease in cell proliferation was evident in all cell types, whereas in fibroblasts an increase in cell death via apoptosis has also been observed. Anatase TiO2 in 20–100 nm-sized form has been shown to be cytotoxic in mouse L929 fibroblasts. The decrease in cell viability was associated with an increase in the production of ROS and the depletion of glutathione. The particles were internalized and detected within lysosomes. In human keratinocytes exposed for 24 h to non-illuminated, 7 nm-sized anatase TiO2, a cluster analysis of the gene expression revealed that genes involved in the “inflammatory response” and “cell adhesion”, but not those involved in “oxidative stress” and “apoptosis”, were up-regulated. The results suggest that non-illuminated TiO2 particles have no significant impact on ROS-associated oxidative damage, but affect the cell-matrix adhesion in keratinocytes in extracellular matrix remodelling. In human keratinocytes, Kocbek et al. investigated the adverse effects of 25 nm-sized anatase TiO2 (5 and 10 μg/ml) after 3 months of exposure and found no changes in the cell growth and morphology, mitochondrial function and cell cycle distribution. The only change was a larger number of nanotubular intracellular connections in TiO2-exposed cells compared to non-exposed cells. Although the authors proposed that this change may indicate a cellular transformation, the significance of this finding is not clear. On the other hand, Dunford et al. studied the genotoxicity of UV-irradiated TiO2 extracted from sunscreen lotions, and reported severe damage to plasmid and nuclear DNA in human fibroblasts. Manitol (antioxidant) prevented DNA damage, implying that the genotoxicity was mediated by ROS.
9. Venator Materials This American company is known for its innovative TIO2 pigments, which are used in paints, plastics, and other industrial applications. Manufacturers operating under the 1317-80-2% classification adhere to strict standards and guidelines to ensure the quality and safety of their output. They employ advanced technologies and innovative processes to synthesize this compound, often requiring a high level of precision and expertise. Their operations involve rigorous research and development phases, quality control measures, and stringent adherence to environmental regulations.A study published in the Journal of Agricultural and Food Chemistry in 2019 sought to examine the effects of titanium dioxide on intestinal inflammation. Researchers did this by feeding rats titanium dioxide nanoparticles and found that, after the course of two to three months, the animals had lower body weights and induced intestinal inflammation. The researchers also found the nanoparticles altered gut microbiota composition and aggravated chronic colitis. The rats also experienced reduced populations of CD4+T cells (which are cells that help organize immune responses by prompting other immune cells to fight infection), regulatory T cells, and white blood cells in mesenteric lymph nodes. The researchers wrote: “Dietary TiO2 nanoparticles could interfere with the balance of the immune system and dynamic of gut microbiome, which may result in low-grade intestinal inflammation and aggravated immunological response to external stimulus, thus introducing potential health risk.”
In addition to quality and reliability, it is also essential to consider the cost-effectiveness of sourcing brilliant blue FCF and titanium dioxide from suppliers. While price should not be the only factor in decision-making, it is crucial to work with suppliers that offer competitive pricing without compromising on product quality or reliability. In conclusion, the price list for China lithopone B311 and B301 provides manufacturers with a cost-effective solution for achieving the desired color and performance properties in their products. With their competitive prices and reliable supply, lithopone B311 and B301 are an excellent choice for a wide range of applications in the paint, coatings, plastics, and rubber industries. With increasing awareness of environmental issues, many companies are now looking for suppliers who prioritize sustainability and environmental responsibility. Look for a coatings titanium dioxide supplier who uses environmentally friendly production processes, such as using renewable energy sources and reducing waste. Additionally, inquire about their policies on recycling and sustainable packaging to ensure that they are committed to minimizing their impact on the environment.The whole scientific experimental design in some of these studies is very flawed, Kaminski said.

Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
Overwhelmingly, research that’s relevant to human eating patterns shows us that E171 is safe when ingested normally through foods and drugs (1,2).
When the pH of titanium dioxide deviates from the optimal range, its properties and performance may be compromised. For example, at low pH levels (acidic conditions), titanium dioxide particles tend to agglomerate and form clusters, leading to poor dispersion and reduced whiteness. On the other hand, at high pH levels (alkaline conditions), the stability of titanium dioxide can be compromised, resulting in decreased opacity and color performance.Lithopone B301
Conclusion
Micronized titanium dioxide doesn’t penetrate skin so there’s no need to be concerned about it getting into your body. Even when titanium dioxide nanoparticles are used, the molecular size of the substance used to coat the nanoparticles is large enough to prevent them from penetrating beyond the uppermost layers of skin. This means you’re getting the sun protection titanium dioxide provides with no risk of it causing harm to skin or your body. The coating process improves application, enhances sun protection, and prevents the titanium dioxide from interacting with other ingredients in the presence of sunlight, thus enhancing its stability. It not only makes this ingredient much more pleasant to use for sunscreen, but also improves efficacy and eliminates safety concerns. Common examples of ingredients used to coat titanium dioxide are alumina, dimethicone, silica, and trimethoxy capryl silane.
