What it is
Diethylhexyl Carbonate is a synthetic dialkyl carbonate ester used widely as an emollient and as a solvent for oil-soluble UV filters. It has a notably light, dry, fast-spreading texture, which makes it popular in sunscreens and stick formats where a non-greasy finish is desired. It also helps reduce the heaviness that high concentrations of UV filters can otherwise impart.
