Abstract: PROBLEM TO BE SOLVED: To provide a product of an ultraviolet-protecting agent having effective action for protecting an organic material, especially the skin and/or the hair of a human from ultraviolet rays, and capable of being compounded readily in an aqueous system or a lipophilic system. SOLUTION: An aqueous dispersion of a scarcely water-soluble or water- insoluble organic UV-filter material containing at least one kind of scarcely water-soluble or water-insoluble organic UV-filter material as an amorphous or partially amorphous colloidal dispersion phase.

Abstract: Aqueous dispersions of difficultly water-soluble or water-insoluble organic UV filter substances (I) contain at least one such substance as a colloidally-dispersed phase in amorphous or partly amorphous form. Independent claims are also included for: (1) the production of the dispersions by (a) treating a molecularly-disperse organic solvent solution of (I) with an aqueous solution of a protective colloid so as to convert the hydrophobic phase of the substance into a colloid disperse phase and then removing the organic solvent or (b) treating a molecularly-disperse organic solvent solution containing (I) and also a water-insoluble polymer with water or with an aqueous solution of a protective colloid so as to convert the hydrophobic phase of (I) and the polymer into a colloid disperse phase and then removing the organic solvent; and (2) production of dry powders by removal of the water and drying optionally in the presence of a coating material, these powders then being optionally converted into double dispersions by emulsifying in an oil.
