This dataset presents experimental results from the study of Pickering emulsions stabilized by natural particles, aiming to compare the interfacial and stability behavior of systems stabilized with carnauba wax solid particles, cellulose nanofibers (CNFs), and sodium caseinate. Emulsions were produced using a two-step process combining rotor-stator pre-emulsification and high-pressure microfluidization. The dataset includes measurements of interfacial tension, interfacial rheology, droplet size distribution, microscopy images, and physical stability over 30 days. The results demonstrated that solid wax particles and CNFs significantly reduced interfacial tension and enhanced emulsion stability compared to protein-stabilized systems. Wax-based emulsions showed a monomodal droplet distribution (D3,2 ≈ 1.87 ± 0.09 µm) and superior long-term stability. The findings provide insights into how natural biocompatible particles can effectively replace conventional surfactants, contributing to the design of more stable and sustainable emulsion-based formulations for food, pharmaceutical, and cosmetic applications.
