摘要 |
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. |
