For decades, TiO2 is used as a white pigment due toits very high opacity and brightness. Therefore, it has a wide range of applications, from colouring ingredient of pharmaceutical film coating, to food application colouring.
On the basis of current discussions on a new classification and labelling of TiO2 and EFSA’s re-evaluation of TiO2 (E171) as a food additive, BIOGRUND is committed to offer alternatives for common film coating formulations. To address this issue, BIOGRUND developed alternatives to replace titanium dioxide in existing film coating systems.
AquaPolish®, formulated without TiO2, provides a comparable white film coating for oral solid dosage forms. Differences to the use of titanium dioxide are not apparent to the eye. The opacity is similar even when used on dark tablet cores.
If required, coloured film coating systems can be replaced TiO2 free. According to customer requirements light-stable natural pigments can be used in the formulation when synthetic colours and iron oxides are not allowed.
