Cosmetic and dermatologic oxygen carrier system
View Patent ↗The invention relates to an oxygen carrier system which is suitable for applying gaseous oxygen to the skin in cosmetic and dermatological forms of application. Said system comprises 0.1 to 10 percent by weight of a liquid perfluorinated or partially fluorinated hydrocarbon or hydrocarbon mixture, 10 to 85 percent by weight of a liquid silicone polymer or silicone polymer mixture, and 5 to 25 percent by weight of an oil base or water base, all percentages being in relation to the total weight of the carrier system. Major moieties of the inventive system can be introduced without stability problems especially into silicone oil-containing formulations.
1. Cosmetic or dermatologic formulation, comprising an oxygen carrier system at 6-10% by weight of the formulation, wherein the carrier system comprises, as a percentage of the carrier system: a liquid perfluorinated or partially fluorinated hydrocarbon or hydrocarbon mixture with a moiety of 0.1-10% by weight, a liquid silicone polymer or silicone polymer mixture with a moiety of 10-85% by weight and a water base with a moiety of 5-25% by weight, and the carrier system being loaded with gaseous oxygen at a partial pressure of 250-400 mbar O 2 .
2. Formulation according to claim 1 , wherein the carrier system is loaded with an oxygen content of 25-40% by volume of the initial oxygen content, as measured at a time four weeks after an initial loading.
3. Formulation according to claim 1 , wherein the carrier system contains tocopherol or a tocopherol derivative with a moiety of 0.01-1.5% by weight, wherein the tocopherol derivative is selected from the group consisting of tocopheryl acetate, tocopheryl succinate, tocopheryl propionate, tocopheryl oleate, tocopheryl linolate, tocopheryl, tocopheryl palmitate, tocopheryl sorbate mixtures thereof and mixtures thereof with tocopherol.
4. Formulation according to claim 1 , wherein the moiety of the liquid silicone polymer ranges from 15-35% by weight.
5. Formulation according to claim 1 , wherein the carrier system contains at least a gelling or thickening agent or a mixture thereof.
6. Formulation according to claim 1 , wherein the oxygen carrier is perfluorodecaline.
7. Formulation according to claim 1 , wherein the moiety of the perfluorinated hydrocarbon or hydrocarbon mixture ranges from 1.5-6% by weight.
8. Formulation according to claim 1 , further comprising a silicone oil with a moiety of 6-35%.
9. Formulation according to claim 1 , wherein the liquid silicone polymer has a moiety of 35-85% by weight.
10. The topical formulation according to claim 9 wherein the topical formulation has the form of a cream, a lotion, a self-tanning agent, a sun protection formulation for use before, during and after the exposure to sun, of a mask, a gel, a spray.
