- Titanium dioxide, or TiO2, is a versatile material known for its exceptional refractive index, UV absorption, and photocatalytic activity. When produced in the nano range, specifically 30-50nm, these characteristics are amplified, opening up a world of possibilities. The 30-50nm TiO2 powders are widely used in applications such as sunscreens, self-cleaning surfaces, air purification systems, and even water treatment technologies due to their superior photocatalytic performance.
- In addition to its UV protection properties, P25 TiO2 also offers high photocatalytic activity. When exposed to sunlight, it can break down organic compounds and pollutants, making it an effective agent for environmental remediation. This property makes P25 TiO2 a valuable addition to paints and coatings, as it can help reduce the amount of volatile organic compounds (VOCs) released into the atmosphere, thereby contributing to air quality improvement.
≥105
After conducting a review of all the relevant available scientific evidence, EFSA concluded that a concern for genotoxicity of TiO2 particles cannot be ruled out. Based on this concern, EFSA’s experts no longer consider titanium dioxide safe when used as a food additive. This means that an Acceptable Daily Intake (ADI ) cannot be established for E171.

Titanium dioxide mainly comes from the earth’s crust, where it’s actually the ninth most common element. When processed, it becomes a fine powder with a vibrant white pigment.
Understanding Anatase Titanium Dioxide
What Is It?
Finally, it's important to consider the global trends impacting the pigment industry as a whole. Environmental regulations, technological advancements, and sustainable practices are increasingly becoming part of the conversation. Suppliers that prioritize eco-friendly production methods or offer biodegradable alternatives may appeal to buyers willing to pay a higher price for sustainably sourced materials.
Lithopone
Lithopone is a mixed zinc sulfide-barium sulfate brilliant white pigment that contains about 30% zinc sulfide. The original light sensitiveness of this pigment has been mitigated by purification and by the addition of such agents as polythionates and cobalt sulfate.
Titanium dioxide exists primarily in three crystalline forms rutile, anatase, and brookite. Among these, anatase is characterized by its unique electronic properties and higher photocatalytic activity, making it suitable for applications requiring enhanced light absorption and reactivity. Its ability to act as a photocatalyst enables the breakdown of organic pollutants, making it a valuable component in environmental remediation strategies.
