The invention concerns a stable emulsion of a non-miscible fluid and an aqueous phase with specific pH. The emulsion is optimized in that it comprises an ionic surfactant and a polyampholytic polymer whereof the charge is pH-dependent. The respective amounts of surfactant and polymers are determined on the basis of the charges. It is possible to adjust by pH control the stabilization or destabilization of the emulsion. The invention also concerns a method for stabilizing and destabilizing an emulsion comprising a surfactant combined with an ampholytic polymer.
La présente invention concerne une émulsion stable d'un fluide non miscible et d'une phase aqueuse ayant un pH déterminé. L'émulsion est optimisée en ce qu'elle comporte un tensioactif ionique et un polymère polyampholyte dont la charge dépend du pH. Les quantités respectives de tensioactif et de polymères sont déterminées en fonction des charges. En contrôlant le pH, on règle la stabilisation ou la déstabilisation de l'émulsion. L'invention concerne également un procédé de stabilisation et de déstabilisation d'une émulsion comportant un tensioactif combiné avec un polymère ampholyte.
