Disclosed is a three-phase emulsion comprising an aqueous-gel outer phase; and a water-in-oil inner phase, wherein the emulsion is stable. The aqueous-gel outer phase can include 10% to 50% by weight of the total weight of the emulsion. This phase can also include 70% to 95% by weight of water based on the total weight of the aqueous-gel outer phase, a gelling agent, and an emulsifier having a hydrophilic-lipophilic balance (HLB) value of 10 to 19. The water-in-oil inner phase can include 50% to 95% by weight based on the total weight of the three-phase emulsion. This phase can also include 50% to 80% by weight of water based on the total weight of the water-in-oil inner phase, 20% to 50% by weight of oil based on the total weight of the water-in-oil inner phase, and an emulsifier.

L'invention porte sur une émulsion à trois phases comprenant une phase externe de gel aqueux ; et une phase interne eau-dans-huile, l'émulsion étant stable. La phase externe de gel aqueux peut comprendre 10 % à 50 % en poids du poids total de l'émulsion. Cette phase peut également représenter 70 % à 95 % en poids d'eau par rapport au poids total de la phase externe de gel aqueux, un agent gélifiant et un émulsifiant ayant une valeur déquilibre hydrophile-lipophile (HLB) de 10 à 19. La phase interne eau-dans-huile peut représenter 50 % à 95 % en poids par rapport au poids total de l'émulsion à trois phases. Cette phase peut également comprendre 50 % à 80 % en poids d'eau par rapport au poids total de la phase interne eau-dans-huile, 20 % à 50 % en poids d'huile par rapport au poids total de la phase interne eau-dans-huile, et un émulsifiant.
