Titanium dioxide (TiO2) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO2 is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.
However, the pigment is expensive, especially when the volume prices of systems are used. And, there always remains a need to develop a full-proof strategy to obtain the best results in terms of cost/performance ratio, scattering efficiency, dispersion… while using it in coating formulations. Are you searching for the same?
Explore the detailed knowledge of TiO2 pigment, its scattering efficiency, optimization, selection, etc. to achieve the best possible white color strength and hiding power in your formulations. - Titanium dioxide powder, a versatile compound with numerous applications in various industries, is primarily used as a pigment due to its excellent whiteness, opacity, and chemical stability. This article delves into the intricacies of a titanium dioxide powder factory, discussing its operations, production processes, and environmental considerations.

In addition to these uses, titanium dioxide is also used in:
- Another advantage of R-906 is its cost-effectiveness. Compared to other grades of rutile TiO2, R-906 offers comparable performance at a lower price point, making it an attractive option for manufacturers and printers seeking to reduce costs without sacrificing quality.

- Firstly, Lithopone B311 powder's primary function lies in its use as a white pigment. It imparts a brilliant white color to products, making it a popular choice in the paint and coatings sector. Its high opacity and ensure effective coverage, reducing the need for excessive layers, thus contributing to cost-effectiveness. Additionally, its stability under heat and light exposure makes it suitable for outdoor applications where durability is paramount.
Most food-grade titanium dioxide is around 200–300 nanometers (nm) in diameter. This size allows for ideal light scattering, resulting in the best color (1Trusted Source).


SURFACES, CHEMISTRY & APPLICATIONS
Titanium dioxide (TiO2). Titanium dioxide is the most common white pigment used today. As a pigment, titanium dioxide is unique because it combines both high colouring and high opacifying capacity. This is mainly due to its high refractive index (2.7). Furthermore, titanium dioxide is an excellent UV absorber (it is used in sun protective creams). Some typical properties are: density 3.3-4.25 g/cm3; pH of water suspension 3.5-10.5; particle size 8–300 nm; oil absorption 10–45 g/100 g; specific surface area 7–160 m2/g. Most titanium dioxide is produced from the rutile (TiO2) or ilmenite (titanate of ferrous iron). Titanium dioxide can be obtained using different processes.
Another crucial property of TiO2 is that it can show photocatalytic activity under UV light. This makes it effective for environmental purification, for different kinds of protective coatings, sterilisation and anti-fogging surfaces, and even in cancer therapy.
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.
Is titanium dioxide illegal in other countries?
How we’re exposed to an ingredient matters greatly in terms of our long-term health.
Research shows that inhaling titanium dioxide particles in significant quantities over time can cause adverse health outcomes. Unless you work in an industrial setting, inhaling substantial amounts of titanium dioxide is highly unlikely.
All food businesses currently using titanium dioxide as a food additive have a legal responsibility to comply with the requirements of Regulation (EU) 2022/63, banning the use of titanium dioxide. The FSAI encourages food businesses to source suitable alternatives to titanium dioxide and start the process of reformulation now to ensure compliance in advance of the ban coming into force on 7 August 2022.
