The fluorescence spectroscopy is As can be seen from Equation 5, an optical method in which the fluorescence energy is always less analyte molecules are excited by than the absorption energy for a given photon absorption, originating species molecule.

Thus, the emitted light is whose emission spectrum provides observed at longer wavelengths than information for qualitative and the excitation With the cosmetics. Thus, the fluorescence molecule in this excited state, spectroscopy would help in identifying relaxation can occur via fluorescence these molecules that act as physical 52 resulting in the emission of light.

The of other metals that may be 54 fluorescence process could be written present.

In other words, this rates of radioactivity and non- technique can determine the radioactivity of the organic 56 uniformity of the layer of sunscreen components. These may occur on the skin through the emission of through the transfer of load and light intensity and thus determine the interactions involving hydrogen bonds optimal concentration of sunscreens formed within the molecule or solvent, by body region.

However, for the vast resulting in conformational majority of sunscreens, which produce changes In general, the use of relatively low levels of fluorescence spectroscopy helps autofluorescence, it will be necessary identify the effects of processes to add suitable fluorescing agents. In summary, in growing portion of the population. It is necessary to reproducible results.

Efforts are emphasize the need to develop a underway by a number of research methodology effective in vitro, to goups to help reduce the complex determine quantitatively the variables to a single reliable test susceptibility of optical products, since method.
