Film Coating: Replacement of titanium dioxide (TiO₂) in tablet film coatings

The white pigment TiO₂ is known for its high opacity and brightness. For this reason, it has a wide range of applications, from the coloring ingredient in pharmaceutical tablet coatings to the popular food coloring.

Depending on the product, it is sometimes necessary to use film coatings without TiO₂. This may be due to scuffing (an abrasive interaction between TiO₂ in the tablet coating and the coater’s stainless steel walls), rumours of nanoparticles and related changes in regulations or customers seeking to achieve a more natural list of ingredients. BIOGRUND formulates its powder mixture like AquaPolish^®, also TiO₂ free. In this way users are offered tailor-made solutions that meet their formulation requirements. TiO₂ free AquaPolish^® is formulated with alternative white dyeing auxiliaries. This makes it possible to replace TiO₂ without sacrificing the usual opacity and brightness of your product. If necessary, colored film coating systems can also be used to replace TiO₂. Depending on customer requirements, light-stable natural pigments are then used in the formulation when synthetic colors and iron oxides are undesirable.
