Parteck® TA (Calcium Carbonate): Enhanced opacity with ideal particle properties
Parteck® TA (Calcium Carbonate): Enhanced opacity with ideal particle properties
Titanium dioxide is extensively used in solid dosage forms as an opacifier and colorant. Due to regulatory developments and restrictions by authorities, formulators are increasingly interested in titanium dioxide-free solutions for both dietary supplements and medicinal products. Uniform colored and white coatings applied to tablets not only have an aesthetic function but also improve patient compliance.
Parteck® TA excipient – Mercks titanium dioxide alternative – has been developed to address the need for an appealing white finish that does not use titanium dioxide. Its unique morphology and designed particle size distribution ensures enhanced opacity, even for challenging pre-colored tablets cores.
This mineral pigment performs excellently when used in HPMC- and PVA-based film coatings for immediate release tablets, thereby allowing higher pigment concentrations while maintaining high process efficiency. An ideal choice of film coating agent is Parteck® COAT (art. 141517), a PVA-based excipient that is even able to achieve increased opacity compared to standard HPMC-containing formulations.
Parteck® TA helps you to achieve a level of covering and whiteness comparable to TiO2-containing film coatings without affecting your tablets’ performance, making it a suitable alternative to titanium dioxide.
