| abstract |
The invention provides a composition comprising at least two immiscible fluid phases separated by a fluid-fluid interface, in which the interface is stabilised by an assembly of biopolymeric microparticles adsorbed at the interface, characterised in that the properties of the interface are modified via the association of at least one functional group on the biopolymer for example hydroxypropyl methyl cellulose phthalate with at least one ligand for example eosin. This enables, for example, the production of coloured emulsions and in particular coloured foams and bubbles. |
