Titanium dioxide (TiO₂) is a naturally occurring oxide of titanium, widely used as a white pigment in various applications due to its brightness and very high refractive index. It is commonly incorporated into paints, coatings, plastics, paper, inks, foods, and personal care products like sunscreens for its opacity and UV blocking properties.
Key Features
- High chemical stability and non-reactivity
- Excellent opacity and whiteness
- Strong UV absorption and reflection capabilities
- Insoluble in water and most solvents
- Widely used as a pigment in industrial and consumer products
Pros
- Exceptional whiteness and brightness enhances product aesthetics
- Provides effective UV protection in sunscreens
- Chemically stable and resistant to degradation
- Non-toxic when used appropriately in many applications
Cons
- Potential environmental concerns regarding nanoparticle forms
- Possible respiratory health hazards if inhaled as airborne particles during manufacturing or grinding
- Not biodegradable, leading to environmental persistence
- Controversy over safety in certain uses (e.g., ingestion or inhalation)
