Patent ID: 7645804

Claim:
A process for the formulation of a complex oil-in-water emulsion, comprising the steps of: determining desired gustatory, pharmaceutical, dermatological or cosmetic properties and functions to be exhibited by the complex oil-in-water emulsion; choosing at least two individual emulsions, each individual emulsion exhibiting at least one of the properties or functions which are to be exhibited by the complex oil-in-water emulsion; optionally diluting at least one of the individual emulsions with an aqueous phase; mixing a first individual emulsion exhibiting at least one of the gustatory, pharmaceutical, dermatological or cosmetic properties or functions with at least a second individual emulsion exhibiting at least one of the gustatory, pharmaceutical, dermatological or cosmetic properties or functions, either of which have optionally been diluted beforehand, the mixture of individual emulsions to form a complex oil-in-water emulsion, the gustatory property or function being selected from the group consisting of a taste, a flavoring, a feeling in the mouth, an enrichment in vitamins, an enrichment in essential fatty acids, the pharmaceutical property or function being a pharmaceutical activity, and the dermatological or cosmetic property or function being selected from the group consisting of combating aging, healing, limiting secretion of seborrhea, cleaning, protecting against UV radiation, moisturizing, emmollience, astringency, sunscreen, antiwrinkle, anti-inflammatory and cell regeneration; and optionally diluting the mixture of individual emulsions with an aqueous phase, each of said individual emulsions being a stable oil-in-water emulsion obtained from an air-in-water preemulsion consisting essentially of a mixture with air of three components: a nonionic surfactant, a hydrophilic cosurfactant, and an aqueous phase, the components being present in ratios chosen within a region of ordered liquid crystal structure of the phase diagram of these three components or in ratios chosen so that the structure of the mixture of these three components, observed under an optical microscope in polarized light, exhibits birefringence characteristics, and a simple or complex fatty substance being added to said preemulsion by mixing to form a gel, said fatty substance being selected from the group consisting of fatty acid esters, waxes, butters, wax esters, natural, synthetic or mineral oils, hydrogenated oils and mixtures thereof.
