In order to evaluate the penetration of the nanoparticles, eight adult male Wistar rats (3 months old) were used for the in vivo experiments. The protocol was approved by the local University Committee for animal testing and is in accordance with the Canadian Council on Animal Care (CICUAL-RD-2021–892-E-UNC-DEC#FCQ).

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.”
- The R960 TIO2 Suppliers A Pivotal Force in the Technological Landscape
- One of the key factors to consider when choosing a TiO2 supplier is the quality of the product they offer. High-quality TiO2 should have excellent brightness, opacity, and dispersion properties, as these characteristics directly impact the final appearance and functionality of the end product. An excellent white TiO2 supplier will have a reputation for consistently producing top-quality products that meet or exceed industry standards.

- Wholesale suppliers of these paints cater to a wide range of needs, from small-scale local contractors to large-scale international projects. They understand the importance of providing high-quality, cost-effective solutions that meet the stringent standards of road safety. These paints are available in various colors and formulations, allowing flexibility in design and functionality. For instance, they can be formulated to glow in the dark, enhance visibility during rainy conditions, or contain reflective particles for improved nighttime navigation.
- In the field of coatings, the combination of talc and titanium dioxide is a game-changer. These minerals can provide excellent hiding power, whiteness, and durability to coatings. Talc, with its high opacity, helps to conceal the underlying surface, while titanium dioxide, with its superior whiteness and UV protection properties, ensures that the coating remains bright and vibrant over time.

What is an exposure route?
On November 23, 2022, the General Court of the European Union reversed the conclusion that titanium dioxide was carcinogenic and released a statement (1,2):
“First, the Commission made a manifest error in its assessment of the reliability and acceptability of the study on which the classification was based and, second, it infringed the criterion according to which that classification can relate only to a substance that has the intrinsic property to cause cancer.”
As part of our mission at CRIS we base our safety assessments on the currently available scientific evidence and consider many variables (e.g., study quality, journal of publication, etc.), even if it goes against previous conclusions. Evidence-informed decisions making is critical to ensure that the laws and regulations put into place are for the benefit of the population.
The EU General Court maintains that the scientific evidence presented wasn’t the complete picture for the ingredient, “in the present case, the requirement to base the classification of a carcinogenic substance on reliable and acceptable studies was not satisfied.”- Lithopone Pigments An In-depth Look at the Manufacturing Process and Global Impact
- Moreover, TiO2's photocatalytic properties have revolutionized the field of environmental remediation. When exposed to sunlight, TiO2 can break down organic pollutants into harmless substances, making it effective in air and water purification systems. It's increasingly being used in self-cleaning surfaces, anti-fouling coatings, and even in air purifiers, contributing significantly to a cleaner environment.
- Furthermore, investing in research and development to explore safer alternatives, such as coated TiO2 particles to reduce dust generation, can be a proactive approach towards enhancing safety in the industry.

For people in occupational settings that increase the risk of titanium dioxide exposure, taking protective measures is helpful. This may include wearing protective equipment, such as respirators, and using ventilation systems.
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.
- In the dynamic world of industrial chemicals, titanium dioxide stands out as a critical component with widespread applications ranging from paints and coatings to plastics and paper. Within this sector, the production of high-quality rutile titanium dioxide pigment is paramount. The pursuit of excellence leads us to an intriguing exploration of the best pigment rutile manufacturers globally.
In an early study Jani et al. administred rutile TiO2 (500 nm) as a 0.1 ml of 2.5 % w/v suspension (12.5 mg/kg BW) to female Sprague Dawley rats, by oral gavage daily for 10 days and detected presence of particles in all the major gut associated lymphoid tissue as well as in distant organs such as the liver, spleen, lung and peritoneal tissue, but not in heart and kidney. The distribution and toxicity of nano- (25 nm, 80 nm) and submicron-sized (155 nm) TiO2 particles were evaluated in mice administered a large, single, oral dosing (5 g/kg BW) by gavage. In the animals that were sacrificed two weeks later, ICP-MS analysis showed that the particles were retained mainly in liver, spleen, kidney, and lung tissues, indicating that they can be transported to other tissues and organs after uptake by the gastrointestinal tract. Interestingly, although an extremely high dose was administrated, no acute toxicity was observed. In groups exposed to 80 nm and 155 nm particles, histopathological changes were observed in the liver, kidney and in the brain. The biochemical serum parameters also indicated liver, kidney and cardiovascular damage and were higher in mice treated with nano-sized (25 or 80 nm) TiO2 compared to submicron-sized (155 nm) TiO2. However, the main weaknesses of this study are the use of extremely high single dose and insufficient characterisation of the particles.
- At the heart of our facility lies a state-of-the-art production line that embodies precision and efficiency. The journey from raw ore to the final TiO2 product is a meticulously orchestrated sequence of beneficiation, calcination, and chlorination processes. Each step is finely tuned to ensure the highest purity and consistent particle size distribution—key attributes that define the performance of the end product.

Resumen–En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.
