TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The emulsion of (I) is capable of being dispensed from an aerosol container using the propellant contained within the container. The aerosol container has a dispensing valve and contains (I) in the form of an emulsion comprising at least one sunscreen agent and a propellant such that in response to operation of a dispensing valve of the container, the propellant dispenses (I) from the container in the form of a spray, mist, fog or similar facilitating application of a substantially uniform film of (I) to the skin. (I) comprises at least one sunscreen agent, an emulsifier, a stabilizer, a neutralizer and/or a propellant base including at least one propellant. (I) comprises a range of different sunscreen agents that provides protection over the infra-red radiation. (I) includes the sunscreen base mixture at 1-90 (preferably 60-65) wt.%. (I) is in the form of an emulsion, and emulsion/suspension or an emulsion and suspended particles mixture, including an oil in water emulsion, a water in oil emulsion or a oil in water in oil emulsion or a water in oil in water emulsion. The non aqueous phase of the emulsion is a solvent, including an organic solvent, and a hydrophobic material such as oils, waxes, waterproofers, emollients, esters, silicons or waxes. The propellant is a gas or mixture of gases including a compressed gas or mixture of gases, or includes a volatile material such as a load boiling point liquid. The spray is in the form of a fine particle size or droplet size spray, mist, fog, aerosol or similar form. The spray has a particle size or droplet size of 0.01-5000 (preferably 1-50) micron. The sunscreen base mixture is in the form of an emulsion and includes e.g. sunscreen agents, emulsifiers, waterproofing agents, film formers, solvents, inorganic materials, esters, perfumes, antioxidants and preservative materials. (I) comprises the sunscreen agents at 1-40 wt.%. The emulsifier comprises the emulsion at 0.1-20 (preferably 1-5) wt.%.Preferred Components: The sunscreen agent is e.g. para-aminobenzoic acid (PABA), benzophenone 1, benzophenone-2, benzophenone-3, benzophenone-4, benzophenone-5, benzophenone-6, benzophenone-8, benzophenone-9, benzophenone-12, ethyl dihydroxypropyl-PABA, glyceryl PABA, homosalate, methyl anthranilate, octocrylene, octyl dimethyl PABA, octyl methoxycinnamate, octyl salicylate, 2-phenylbenzimidazole-5-sulfonic acid, triethanolamine salicylate, 4-methylbenzylidene camphor and red petrolatum. The propellant is propane, dimethylether, isobutant, n-butane, vinyl chloride or blends or combinations of two or more such propellants including gases such as nitrogen, carbon dioxide, nitrous oxide or hydrocarbons, and halogenated hydrobarbons. ACTIVITY - Dermatological.    MECHANISM OF ACTION - None given.    ADMINISTRATION - Administration of (I) is topical.    EXAMPLE - Typical sun screen composition comprises (%w/w): an oil phase (comprising solvent (0-30; preferably 5-20), film former (0-10; preferably 0.5-10), fatty acid (0-10; preferably 1-8), emulsifier (0-10; preferably 0.1-3), waterproofer (0-20; preferably 0.1-5), UV filters (0-30; preferably 5-20), antioxidant (0-5; preferably 0.01-0.5), wax (0-10; preferably 1-8) and preservative (0-2; preferably 0.1-1.5)), a water phase comprising (water (0-90; preferably 20-70), humectant (0-40; preferably 5-20), thickener (0-15; preferably 0.1-5), neutralizer (0-15; preferably 0.1-2), emulsifier (0-10; preferably 0.1-5) and sequestering agent (0-5; preferably 0.01-2)), preservatives (0-10; preferably 0.1-2), fragrance (0-5; preferably 0.05-2) and propellants (0-60; preferably 2-50) (claimed).
