Pharmaceutical grade titanium dioxide is primarily composed of TiO₂ and is specifically manufactured for use in pharmaceutical compounds. It’s primarily employed as a whitening, opaque, and coating substance in solid formulations that have a significant appearance consistency, stability, and regulatory compliance.
Compared to industrial or food-grade titanium dioxide, pharmaceutical-grade titanium dioxide is more stringent regarding purity, size control of particles, heavy metal salts, safety of microbiology, and consistency between batches. It must follow recognized pharmacopeial rules, such as theUSP, EP, BP, or other relevant regulations, depending on the market.
Pharmaceutical-grade titanium dioxide is commonly employed in the production of tablets to enhance their uniform whiteness, opacity, and light protection. It facilitates the masking of the core color variations and enhances the overall visual appeal of the finished tablets.
In both hard and soft capsules, titanium dioxide increases the opacity of the shell, shields the light-sensitive components of the shell, and guarantees a consistent appearance throughout the manufacturing process.
In modified-release, enteric, and protective coatings, pharmaceutical-grade titanium dioxide has a role in the uniformity and stability of the coating without negatively impacting the release profile of the drug.
It’s also employed in vitamins, minerals, and dietary supplements to enhance the appearance, identity, and maintain consistency of products.
Pharmaceutical-grade titanium dioxide is incorporated into dosage forms intended for animals; the same safety, stability, and design requirements are required of these forms.
Pharmaceutical-grade titanium dioxide is produced according to the pharmacopeial standards and quality systems associated with pharmaceuticals; this production process guarantees compliance with global regulations.
rigorous oversight of heavy metals, residual chemicals, and microbiological parameters that are relevant to medicinal uses.
Its high index of refraction facilitates the masking of imperfections and the uniform coloring of products, which enhances the appearance of the product and promotes consistency in the brand.
Pharmaceutical-grade titanium dioxide is chemically inactive and stable, which makes it compatible with a large variety of pharmaceutical ingredients (APIs) and additives.
Constant particle size distribution and standardized manufacturing processes facilitate reproducible coating performance and high production stability.
