METHOD FOR OBTAINING AN EMULSION CONTAINING AN INTERNAL HYDROPHOBIC PHASE DISPERSED IN A CONTINUOUS HYDROPHILIC PHASE

Abstract : The invention relates to a method for producing an emulsion includinga hydrophobic internal phase dispersed in a hydro philic 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)producingan oil-in-wateremulsion composition that has a hydrophobic phase/hydrophilic phase volume ratio of at least 5/95, includinga 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 per centage higher than 55%, including: b.1) a step foradding a volume ofhydrophobic 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.
