Titanium dioxide white color
Titanium Dioxide (White Color) is a fine, white, inorganic compound widely used in pharmaceutical and laboratory applications for its opacity, brightness, and UV-protective properties. It appears as a white, odorless powder that is practically insoluble in water and organic solvents but disperses easily in formulations to provide uniform color and opacity.
🏭⚗️ Production
Titanium dioxide is produced from naturally occurring titanium ores such as ilmenite and rutile. The production process involves either the sulfate method or the chloride method, both yielding highly purified titanium dioxide suitable for pharmaceutical and laboratory applications. The resulting material is micronized and standardized for particle size, purity, and brightness to ensure consistent quality in medical and analytical use.
🔬 Properties
Titanium dioxide is a white, odorless, and tasteless powder with high refractive index and excellent covering power. It is insoluble in water and most organic solvents but can be uniformly dispersed in aqueous and non-aqueous systems. It is chemically stable, non-reactive, and resistant to discoloration under normal conditions. Titanium dioxide also exhibits UV-absorbing properties, providing protection and stability in light-sensitive formulations.
🧪 Applications
In pharmaceutical formulations, titanium dioxide is primarily used as a white pigment and opacifier in tablet coatings, capsules, and topical preparations. It enhances visual appearance, provides consistent color, and protects light-sensitive ingredients from degradation. In laboratory settings, titanium dioxide is used as a reference material, pigment standard, and in photocatalytic and UV-absorption studies. Its inertness and stability make it suitable for controlled experiments and analytical formulations.
⚠️ Safety
Titanium dioxide is generally recognized as safe for pharmaceutical and laboratory use when handled properly. However, fine powders can cause irritation if inhaled or come into contact with eyes. Protective gloves, goggles, and masks should be worn when handling powdered material. The product should be stored in tightly closed containers, in a cool, dry, and well-ventilated area, away from moisture and direct sunlight to maintain its purity and stability.
