In this episode of Excipient Talk, Dr. Michael Black speaks with Daria Kobiakova about how titanium dioxide‑free tablet coatings can be developed in practice. Daria shares insights from a case study carried out with an academic partner in Poland, explaining why the industry is searching for alternatives to titanium dioxide and what makes it so difficult to replicate its whitening and opacifying properties. The conversation explores how a combination of isomalt and calcium carbonate can create white, visually appealing coatings, what formulation challenges may arise, and what companies should consider when moving away from titanium dioxide today.
