| 主权项 | 1. A composition in the form of an emulsion comprising a hydrophobic phase dispersed in an aqueous phase, which composition contains emulsifying particles capable of stabilizing said emulsion, wherein said particles comprise cellulose nanocrystals having an elongated shape with a length ranging from 25 nm to 1 μm, and a width ranging from 5 to 30 nm, wherein the composition is a Pickering emulsion which is devoid of surfactants and wherein when the ionic strength of the composition is less than 10 mM, the cellulose nanocrystals have a surface charge density of 0.03 e nm−2 or less, where e stands for the elementary electric charge. | ||
