Preformulation Studies and Development of a Herbal Tooth Powder Using Coconut Shell as a Natural Abrasive

The present study focuses on preformulation investigations and formulation development of a herbal tooth powder incorporating coconut shell powder as a natural abrasive. Coconut shell, an abundantly available agricultural by-product, was processed and standardized to obtain a suitable particle size for oral-care application. Preformulation studies were carried out to evaluate flow properties and powder characteristics essential for uniform mixing and formulation stability. Based on preformulation outcomes, multiple batches of herbal tooth powder were formulated using natural excipients. The study demonstrates the feasibility of coconut shell powder as a sustainable, cost-effective abrasive and provides a scientific basis for its inclusion in dentifrice formulations.
