In food, titanium dioxide has a few different uses. Most notably, its food-grade form is used as a colorant to enhance and brighten the color of white foods such as dairy products, candy, frosting, and the powder on donuts. For foods that are sensitive to UV light, titanium dioxide is used for food safety purposes to prevent spoilage and increase the shelf life of food.
- Furthermore, China's extensive network of transportation and logistics infrastructure ensures that titanium dioxide can be easily exported to international markets
- The manufacturing process of TIO2 pigment involves either the sulfate or chloride process. Each method yields different types of TIO2 particles, which can affect the final product's performance and application. The sulfate process typically produces anatase, a crystalline form of TIO2, while the chloride process yields rutile, another crystalline form known for its superior durability and refractive index.
Zhu et al. were the first to provide evidence that TiO2 NPs (21 nm) can transfer from daphnia to zebrafish by dietary exposure. Hence, dietary intake could be a major route of exposure to NPs for high trophic level aquatic organisms. Ecological research should therefore focus, not only on the concentration of NPs in the environment, but also on its bioconcentration, bioaccumulation and biomagnification. In addition it has been shown that TiO2 NPs can increase accumulation of other environmental toxicants: enhanced accumulation of cadmium (Cd) and arsenic (As) was found in carp in the presence of TiO2 NPs. The strong adsorption capacity for Cd and As was explained by the large specific surface area and strong electrostatic attraction of TiO2 NPs that contribute to facilitated transport into different organs.
- Silver titanium dioxide is a remarkable compound with a unique set of properties that make it highly sought after in various industries. This innovative material combines the benefits of silver, an element known for its antimicrobial properties, with those of titanium dioxide, a pigment widely used for its brightness and ability to reflect light. The combination results in a product that not only has excellent color stability and high refractive index but also exhibits strong antibacterial and antifungal characteristics.

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.

The titanium dioxide market fluctuated in the first two quarters of 2023. These pricing patterns resulted from poor demand and reduced intakes from the downstream industries. Amid the slow demand, the manufacturers were forced to reduce their outputs. With rising inflation rates, production cuts gradually increased. Given the economic downturn, the labor strikes further affected the market dynamics, thereby exerting pressure on the pricing fundamentals.
- Today, TiO2 factories employ advanced technologies and rigorous quality control measures to ensure consistent product quality and minimize environmental harm. They also invest in research and development to improve production efficiency and explore new applications for titanium dioxide. For example, some factories have developed nano-sized TiO2 particles that exhibit enhanced UV-blocking properties, making them ideal for use in sunscreens and cosmetics For example, some factories have developed nano-sized TiO2 particles that exhibit enhanced UV-blocking properties, making them ideal for use in sunscreens and cosmetics

Key Questions Answered in This Report:
Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”
For this reason alone, its time to ditch the Titanium Dioxide & give your skin a break from the relentless free radical damage.


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.

When E171 isn’t combined with other ingredients and administered in water, some studies suggest that under these artificial conditions, E171 may be processed differently in the body resulting in some biological changes in experimental animals that are poorly understood.
