Abstract

Highlights: RCs from three plant-derived celluloses have similar networked morphologies. Pickering emulsions can be stabilized by the three RCs. The droplet sizes remained unchanged after seven days of storage for all emulsions. RC source plays an important role in properties of its suspensions and emulsions. Abstract: Regenerated cellulose (RC) has attracted interest for stabilizing emulsions effectively via both Pickering and networking mechanisms. In this study, RCs were prepared from three plant-derived celluloses (wood pulp, bamboo pulp and cotton fabric). The three RCs had similar morphological networks, but their viscosities were 0.55 Pa s, 1.47 Pa s and 2.29 Pa s, respectively. The properties of Pickering emulsions stabilized by the RCs were investigated. The results revealed that the droplet sizes and viscosities of the three emulsions varied. After seven days of storage, the droplet sizes of the emulsions remained unchanged, but the viscosities of the emulsions from wood pulp, bamboo pulp and cotton fabric increased by 163%, 115% and 9%, respectively. These findings demonstrate that the source of RC plays an important role in determining the properties of the resulting suspensions and emulsions, thereby providing guidelines for the preparation of RC-based green emulsions for applications in cosmetics and related formulations.
