CA 2605660

Compositions, devices, methods, and kits are provided for determining the presence of topical compositions on surfaces, such as skin. The invention provides a composition comprising at least one topical agent and a fluorescent chromophore having a wavelength of excitation, the topical agent having a first absorbance when measured at said wavelength and the fluorescent chromophore having a second absorbance when measured at said wavelength, wherein the ratio of the second absorbance to the first absorbance is at least about 5. The invention further provides a kit comprising: a) a first composition comprising a topical agent and a first concentration of fluorescent chromophore; and b) a second composition comprising the topical agent and a second concentration of the fluorescent chromophore, wherein the first concentration is substantially greater than the second concentration.

L'invention concerne des compositions, dispositifs, procédés et trousses permettant de déterminer la présence de compositions topiques sur des surfaces, comme la peau.
