Titanium dioxide (TiO₂) is used mainly as a white pigment and opacifier in paints, coatings, plastics, printing inks and paper. Different grades are also used in cosmetics, ceramics and photocatalytic materials. The correct grade depends on the crystal form, particle characteristics, surface treatment, production route and final application.
For industrial buyers, “titanium dioxide” is not one interchangeable product. A coatings-grade rutile pigment, a plastics grade and a photocatalytic anatase material can have very different performance requirements. This guide explains seven major applications and the information buyers should compare before requesting a quotation.
What Is Titanium Dioxide?
Titanium dioxide is an inorganic compound with the formula TiO₂ and CAS number 13463-67-7. Pigment-grade TiO₂ scatters visible light efficiently, giving formulated products whiteness, brightness and opacity. The two main commercial crystal forms are rutile and anatase.
- Rutile TiO₂ is commonly selected for paints, industrial coatings, plastics and inks where opacity and durability matter.
- Anatase TiO₂ is used in selected indoor applications, paper, ceramics and photocatalytic systems, depending on the grade and treatment.
Buyers looking for an industrial pigment can review YuXing’s rutile titanium dioxide product page or browse the broader pigments and coatings chemicals category.
7 Major Uses of Titanium Dioxide
| Application | Main Function | Typical Buying Focus |
|---|---|---|
| Paints and coatings | Whiteness, opacity and weather resistance | Rutile grade, surface treatment, hiding power, gloss and dispersion |
| Plastics and masterbatch | Color, opacity and UV-related durability | Thermal stability, dispersion, undertone and processing compatibility |
| Printing inks | White opacity and print contrast | Dispersion, tint strength, viscosity impact and ink-system compatibility |
| Paper and paper coatings | Brightness and opacity | Particle characteristics, retention, brightness target and cost-performance balance |
| Cosmetics and sunscreens | Color or UV-filter function in approved grades | Particle form, purity and market-specific regulatory compliance |
| Ceramics and glass | Color, opacity and functional properties | Crystal form, purity, firing behavior and formulation compatibility |
| Photocatalytic materials | Light-activated surface reactions | Anatase activity, particle form, coating system and exposure conditions |
1. Paints and Industrial Coatings
Paint and coating manufacturers use pigment-grade TiO₂ to improve whiteness, hiding power, opacity and brightness. Exterior architectural paints and industrial finishes may also require gloss retention and weather resistance. Rutile titanium dioxide is usually the main starting point for these demanding coating applications.
Grade selection should consider the coating system rather than TiO₂ content alone. Surface treatment, dispersibility, oil absorption, tint strength and the intended interior or exterior exposure can all influence finished-film performance.
2. Plastics and Masterbatch
Titanium dioxide gives plastic products a bright white appearance and improves opacity. It is used in pipes, profiles, films, molded parts, packaging and masterbatch. A plastics grade should be reviewed for dispersion, thermal processing behavior, moisture, undertone and compatibility with the polymer system.
Using a general coatings grade in a demanding plastics process can create avoidable problems such as poor dispersion or inconsistent appearance. Buyers should send the polymer type, processing temperature and required end use when asking for a grade match.
3. Printing Inks
White printing inks use TiO₂ for opacity and contrast on packaging, labels and other printed materials. Ink formulators normally compare dispersion, tint strength, gloss, particle characteristics and viscosity impact. The selected pigment must also suit the resin and solvent or water-based ink system.
4. Paper and Paper Coatings
Titanium dioxide can improve the brightness and opacity of high-value paper and paper coatings. It helps reduce show-through where print quality is important. Because TiO₂ is a premium pigment, paper manufacturers usually balance optical performance against retention, formulation and cost requirements.
5. Cosmetics and Sunscreens
Approved titanium dioxide grades may be used as color additives or UV filters in cosmetic and sunscreen formulations. These applications require different purity, particle and regulatory controls from ordinary industrial pigment grades. Buyers should never assume that a coatings-grade material is suitable for cosmetic use.
6. Ceramics and Glass
TiO₂ is used in selected ceramic bodies, glazes and glass formulations to influence color, opacity, crystallization or other functional properties. The correct grade depends on purity, crystal form, firing conditions and the other materials in the formulation.
7. Photocatalytic and Self-Cleaning Materials
Selected anatase TiO₂ grades can participate in light-activated reactions and are used in research and commercial photocatalytic coatings, self-cleaning surfaces and environmental-treatment materials. Performance depends on particle form, formulation, UV exposure and contact conditions; it should not be inferred from the product name alone.
Rutile vs. Anatase Titanium Dioxide
| Selection Point | Rutile | Anatase |
|---|---|---|
| Common focus | Opacity, durability and broad pigment use | Brightness and selected photocatalytic or specialty uses |
| Typical applications | Exterior and interior coatings, plastics, inks | Selected indoor products, paper, ceramics, photocatalytic systems |
| Weather resistance | Generally preferred for demanding exterior applications | Usually less suitable where long-term exterior durability is the priority |
| Purchasing decision | Confirm the exact grade, surface treatment, TDS and application test results | |

How to Choose an Industrial Titanium Dioxide Grade
- State the application. Identify the paint, coating, ink, plastic, paper, ceramic or other formulation.
- Provide a reference grade or target TDS. This is more useful than requesting “high-quality TiO₂” without measurable requirements.
- Define the performance target. Include opacity, whiteness, gloss, tint strength, dispersibility, weather resistance or processing requirements.
- Review surface treatment and production route. Chloride- and sulfate-process grades, plus inorganic and organic treatments, can behave differently in the final formulation.
- Check documentation. Request the current TDS, SDS/MSDS and a representative or batch COA.
- Confirm packaging and shipment. State quantity, destination port, bag and pallet requirements and any import-document needs.
- Test the proposed grade. Application trials remain important when replacing an established pigment.
Safety and Regulatory Considerations
Regulatory status depends on the market and end use. The U.S. FDA permits titanium dioxide as a food color additive under specified conditions, including a limit of 1% by weight of the food. In the European Union, Commission Regulation (EU) 2022/63 removed the authorization for E171 in foods. Food, cosmetic, pharmaceutical and food-contact applications therefore require grade-specific and destination-specific regulatory review.
For workplace handling, titanium dioxide is a fine powder and dust exposure should be controlled. Review the product SDS, use suitable ventilation and personal protective equipment, and follow applicable occupational requirements. NIOSH guidance distinguishes occupational exposure considerations for fine and ultrafine TiO₂.

FAQ
What is titanium dioxide mainly used for?
Titanium dioxide is mainly used as a white pigment and opacifier in paints, coatings, plastics, printing inks and paper. Specialized grades are also used in cosmetics, ceramics and photocatalytic materials.
Is rutile or anatase titanium dioxide better for paint?
Rutile TiO₂ is generally preferred for paints and industrial coatings that require opacity and exterior durability. The correct choice still depends on the formulation, surface treatment and target performance.
Can the same titanium dioxide grade be used in paint and cosmetics?
Not automatically. Industrial, cosmetic, food and pharmaceutical grades have different purity, particle and regulatory requirements. Use only a grade documented and approved for the intended application and destination market.

Request the current TDS, SDS/MSDS and a representative or batch COA. For export procurement, also confirm packaging, invoice, packing list, HS classification and destination-specific shipment documents.
What information is needed for a titanium dioxide quotation?
Provide the application, crystal form, reference grade or target specification, quantity, packaging, destination port and required technical or shipping documents.
