Abstract: The composition, advantageously an emulsion or a foam, includes an internal phase dispersed in a hydrophilic continuous phase, the percentage of the internal phase being higher than 50%. The emulsion composition contains nanocrystals of a polysaccharide other than cellulose, advantageously chitin, that are located at the interface between the internal phase and the hydrophilic continuous phase.

Abstract: The present invention relates to a composition in the form of an emulsion, advantageously a Pickering emulsion, comprising a hydrophobic phase dispersed in an aqueous phase, which composition contains emulsifying particles capable of stabilizing said emulsion, at least some of said particles consisting of cellulose nanocrystals having an elongated shape, which have the following features: a length between 25 nm to 1 ?m, and a width between 5 to 30 nm.

Abstract: The invention relates to a method for producing an emulsion including a hydrophobic internal phase dispersed in a hydrophilic continuous phase, of the medium internal phase (MIPE) or high internal phase (HIPE) type, which has an internal phase percentage higher than 55%, comprising the following steps: a) producing an oil-in-water emulsion composition that has a hydrophobic phase/hydrophilic phase volume ratio of at least 5/95, including a step for incorporating cellulose nanocrystals into said hydrophilic phase, and a step for forming the emulsion by dispersing said hydrophobic phase in said hydrophilic phase, and b) producing an emulsion that has an internal phase percentage higher than 55%, including: b.1) a step for adding a volume of hydrophobic phase to the emulsion composition produced in Step a), and stirring the mixture thereby produced, and/or b.2) a step for concentrating the emulsion composition produced in Step a), by removing at least part of said hydrophilic phase.
