Abstract

Procedure for the preparation of water dispersible coloring agents, characterized by concentrating, at least until the volatile organic solvent has been removed, a solution of one or more crocetínicos esters of the formula **(See formula)** wherein R1 and R2 are alkyl containing in total 16 to 40 carbon atoms, in a volatile organic solvent for carotenoids, together with a physiologically compatible emulsifier and, if desired, in the presence of water and, in concentrating until dryness, optionally disperse the residue in water.
