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.
Claims18
A composition, comprising:
- an internal phase dispersed in a hydrophilic continuous phase, the percentage of the internal phase being higher than 50%, wherein
- said composition contains nanocrystals of a polysaccharide other than cellulose, which are located at an interface between said internal phase and said hydrophilic continuous phase,
- the nanocrystals of a polysaccharide other than cellulose are selected from nanocrystals which are positively charged, and
- the nanocrystals of a polysaccharide other than cellulose comprise chitin nanocrystals which are in the form of anisotropic rods, wherein
- said chitin nanocrystals have not been functionalized or grafted.
