About TiO2

Titanium dioxide is a naturally occurring oxide of titanium. It has the highest refractive index of any material known to man, even the diamond, and is one of the whitest materials on earth. When produced as a fine powder, it transforms into a pigment that provides maximum whiteness and opacity. TiO2 pigments are used in paints and coatings, plastics, paper, building materials, cosmetics, pharmaceuticals, inks and many other commercial products.

However, nature does not yield titanium dioxide in a usable form. It must be carefully mined in one of its pure forms, such as rutile beach sand, and refined into a fine uniform particle size. KRONOS uses both the chloride and sulfate production processes to accomplish this.

Titanium Dioxide R:

Possessing a purity of 93.5%, it is a rutile pigment with alumina, zirconia, and organic surface treatment. It is characterized by high whiteness and glossiness, high dispersibility, durability, and excellent dispersion.

Suitable for:

Interior and exterior paints, emulsion paints, powder coatings, inks, paper, rubber, plastics, and masterbatches.

Titanium dioxide is produced in two primary forms. The primary form, accounting for over 98% of total production, is pigment-grade titanium dioxide. The pigment form utilizes the excellent light-dispersing properties of titanium dioxide in applications requiring whiteness and brightness. The other form in which titanium dioxide is produced is as an ultrafine (nanomaterial) product. Titanium Dioxide (TiO2) is a solid white mineral substance that is thermally stable, non-flammable, poorly soluble, and not classified as hazardous.

Titanium dioxide is a titanium oxide with the formula TiO2. A natural oxide sourced from ilmenite, rutile, and anatase, pure titanium dioxide is a fine, white powder that produces a bright, white pigment. Rutile TiO2 pigments are preferred as they disperse light more efficiently, are more stable, and have greater durability than anatase pigments. TiO2 is valued for its super white color, light-dispersing ability, and resistance to ultraviolet (UV) light, making it a popular material used daily in hundreds of products, offering significant benefits to the economy and our quality of life.

Applications:

For a century, titanium dioxide has been used in a wide range of industrial and consumer products, including paints, coatings, adhesives, paper, plastics and rubber, printing inks, coated fabrics and textiles, ceramics, floor coverings, roofing materials, cosmetics, toothpaste, soap, water treatment agents, pharmaceuticals, food coloring agents, automotive products, sunscreens, and catalysts.

Paints and Coatings:

Titanium dioxide creates opacity and durability, while ensuring the longevity of the paint and protection of the painted surface.

Plastics, Adhesives, and Rubber:

Titanium dioxide can help minimize brittleness, fading, and cracking that can occur in plastics and other materials due to light exposure.

Cosmetics and Personal Care:

Titanium dioxide pigment is used in some cosmetics to help hide blemishes and brighten the skin. Titanium dioxide allows for the use of thinner layers of cosmetics to achieve the desired effect.

Paper:

Titanium dioxide is used to coat paper, making it whiter, brighter, and more opaque.

The opacity against visible and ultraviolet light provided by titanium dioxide protects foods, beverages, supplements, and pharmaceuticals from premature degradation, extending the product's shelf life. Specific classes of high-purity pigment-grade titanium dioxide are also used in drug tablets, capsule coatings, and as decorative aids in some foods.

Ultrafine-grade titanium dioxide, or nano-grade, is typically used in the following specialized applications:

Sunscreens:

Nano-scale titanium dioxide becomes transparent to visible light while acting as an efficient UV light absorber. Because the particle size is very small, nano titanium dioxide does not reflect visible light but absorbs UV light, creating a transparent barrier that protects the skin from harmful sun rays. According to the Skin Cancer Foundation, the use of sunscreens containing titanium dioxide can prevent skin cancer.

Catalysts:

Nano-scale titanium dioxide is used as a support material for catalyst applications. Major uses are in automotive industry for removing harmful gas emissions and in power plants for removing nitrogen oxides.

Safety Notes

The United States Food and Drug Administration (FDA) has assessed the safety of titanium dioxide pigment as a color additive in food, drugs, and cosmetics, as well as a material in sunscreen products. FDA has also issued guidance on the safe use of titanium dioxide pigment as a food colorant, stating that titanium dioxide may be safely used in cosmetics, including cosmetics intended for use around the eyes.

Are there health concerns associated with exposure to titanium dioxide?

The International Agency for Research on Cancer (IARC) has classified titanium dioxide as possibly carcinogenic to humans based on studies showing increased lung tumors in rats associated with titanium dioxide inhalation. However, extensive studies on industrial titanium dioxide workers do not show a link between occupational exposure to titanium dioxide and an increased risk of cancer in humans.

Exposure to TiO2 does not penetrate healthy skin and poses no local or systemic health risk to human skin exposure. In a study using sunburnt pig ears, researchers applied nano-based sunscreen creams. TiO2 did not reach the deep layer of skin in the sunburnt tissue.

Most concerns arise when TiO2 is inhalable or breathable. For TiO2 inhalation, particles must be small enough to reach the alveoli (where oxygen exchange occurs) in the lungs. Sampling methods for estimating airborne mass concentrations of breathable particles and inhalable dust have been developed.
