Abstract
A perfluorinated oil-in-water biliquid foam is provided as a vehicle for delivering cosmetics and active agents while producing a refreshing and unique contact with the skin, and enhancing the aroma of fragrances within the foam. The biliquid foam contains an oil phase perfluorinated solvent, surfactants, co-solvents, and oil-based ingredients such as aromatic extracts, and a water phase with anionic or hydrophilic surfactants. The biliquid foam may be made by gradually increasing addition of the oil phase to the water phase under moderate mixing conditions. Various other auxillary cosmetic and non-cosmetic components such as vitamins, anti-oxidants, stabilizers, thickeners, dyes, moisturizers, and preservatives may be added to the biliquid foam as well.
