Abstract
Cosmetic skin or hair care compositions containing a liquid, inert, hydrophobic fluorocarbon infused with carbon dioxide. The compositions increase blood flow to the skin, thus increasing endogenous oxygen and nutrient delivery to the skin.
Claims3
A cosmetic skin or hair care oil-in-water emulsion comprising:
- i) from about 0.1% to about 70%, by weight of the emulsion of a fluorocarbon infused with carbon dioxide wherein the fluorocarbon is inert, liquid at 25.degree. C. and hydrophobic and is selected from the group consisting of perfluorooctane, perfluorodecane, perfluorodecalin, perfluorooctylbromide, perfluorodecylbromide, perfluorooctyliodide, perfluorotripropylamine, perfluoro-tributylamine, bis-(F-butyl)-ethene and perfluoro-polymethylisopropyl ether;
- ii) an ingredient selected from the group consisting of a sunscreen in an amount from 0.1 to 25% by weight;
- and a cationic conditioning agent in an amount from 0.01 to 10% by weight;
- iii) a cosmetically acceptable vehicle.
