Implementing organic materials in sunscreen applications

A method, comprising:

• selecting a combination of multiple organic materials to incorporate into a sunscreen composition, wherein said selecting is based at least in part on (i) a desired absorption spectrum of the sunscreen composition, (ii) the absorption spectrum of each of the multiple organic materials, and (iii) a particle size limitation for each of the multiple organic materials, and wherein the multiple organic materials comprise N,N′-Bis(3-methylphenyl)-N,N′-bis(phenyl)-benzidine;
• and
• incorporating the selected combination of organic materials into the sunscreen composition to generate the desired absorption spectrum.
