ABSTRACT:
The invention consists in a ternary system.
The ternary system comprises three phases which are non-miscible with one another and consist of a phase of perfluorinated ethers, an aqueous phase and a phase of silicones comprising at least one straight-chain-silicone containing a glycol group and at least one cyclic-chain silicone containing a methyl group. These silicones can be of the dimethicone copolyol type and of the cyclomethicone type, respectively. And the aqueous phase preferably contains a hydrating agent, a co-emulsifier and an anti-bacterial preservative. The invention concerns in particular cosmetics.
