Abstract (en)
[origin: DE19737737A1] The invention relates to the use of dialkyl carbonates as solvent or dispersing agent in UV filters. The carbonic acid esters display non only excellent dissolving or dispersing properties, but also a high spreading capacity, and they enhance UV absorption in a synergistic way.
