The article discusses new developments to replace titanium dioxide (TiO₂) in tablet coatings. Due to regulatory concerns and consumer demand for cleaner ingredients, researchers at Roquette have created a new hard-coating method using xylitol as a base. This process is compatible with existing equipment and works at speeds similar to traditional film coating. The coating is thicker and crystalline, offering an alternative way to achieve tablet whiteness. Magnesium stearate is also mentioned as a potential whitening agent. This innovation helps pharmaceutical companies meet regulatory requirements while maintaining product quality and appearance.
