TOPICAL COMPOSITION FLUORESCENCE DETECTION

摘要

Compositions, devices, methods, and kits are provided for determining the presence of topical compositions on surfaces, such as skin. Disclosed is in a first embodiment a composition comprising one or more oil or water soluble ultraviolet sunscreen agents and a fluorescent chromophore, wherein the fluorescent chromophore is oil soluble or water-soluble and has a wavelength of excitation greater than about 400nm (so-called daylight fluorescent compound). Also disclosed is a method of manufacturing a topical composition, comprising mixing a fluorescent chromophore and a sunscreen sufficiently to form a single phase composition. Further, a device for use with the fluorescent composition is described, for determining the presence of the composition on a surface, which device comprises a light emitter, a light detector, an electronic evaluation system to determine the level of fluorescence of the fluorescent chromophore, and a display system.
