Patent

CA 2027516

The invention relates to a ternary system. It comprises three non-miscible phases comprised of a perfluorinated ether phase, an aqueous phase and a silicone phase comprising at least one linear silicone with glycol groups, and at least one cyclic silicone with methyl groups. These silicones can be the dimethicone copolyol type (glycol/dimethicone copolymer) and the cyclomethicone type, respectively. The aqueous phase will preferably contain a hydrating agent, a co-emulsifier and an antibacterial preservative. The invention relates specifically to the field of cosmetics.

L'invention se rapporte à un système ternaire Celui-ci comprend trois phases non miscibles entre elles constituées par une phase d'éthers perfluorés, une phase aqueuse et une phase de silicones comprenant au moins une silicone à chaîne linéaire et à groupement glycol, et au moins une silicone chaîne cyclique et à groupement méthyle. Ces silicones pourront êtres respectivement du type copolyol de diméthicone (copolymère de glycol/diméthicone) et du type cyclométhicone. Et la phase aqueuse contiendra de préférence un agent hydratant, un co-émulsionnant et un agent conservateur antibactérien. L'invention concerne en particulier le domaine de la cosmétique.
