This study investigates the fabrication of pickering emulsions using eco-friendly cellulose nanocrystals (CNCs) as solid stabilizers for rosin amine. An energy-efficient phase inversion emulsification (PIE) method was employed, and the influence of CNC concentration on the resulting emulsion structure and long-term stability was systematically evaluated. The evolution of droplet size distribution as a function of CNC concentration was quantified using optical microscopy and Dynamic Light Scattering (DLS). Furthermore, the interfacial behavior of CNCs was elucidated through surface coverage analysis, determining the maximum adsorption capacity required to achieve a stable monolayer. The results provide a fundamental guideline for optimizing the particle-to-oil ratio to ensure robust interfacial shielding in bio-based emulsion systems.
