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.
Claims4
Emulsion comprising three phases non-miscible with one another, said phases consisting essentially of:
- a first phase of about 0.1 to 5% by weight of perfluorinated ether,
- a second phase comprising about 0.1 to 5% by weight of a straight-chain silicone containing a glycol group, as surfactant for forming said emulsion, and about 0.1 to 50% by weight of a cyclic-chain silicone containing a methyl group, as fluid base, and
- a third phase comprising about 3 to 5% by weight of hydrating agent, and water, qs 100.
