The present invention is directed at organic ammonium salts comprising

an organic ammonium-group-comprising cation which does not contain an estolide moiety and a carboxylate anion (COO—) group-comprising anion selected from the group consisting of anions containing at least one estolide moiety or carboxylate anions containing at least one internal ester group.

The invention is also directed at a process for the production of such organic ammonium salts, the use of such organic ammonium salts in cosmetic formulations for skin and hair care, the use of such organic ammonium salts for the treatment of fibers, the use of the organic ammonium salts for the treatment of hair, at compositions containing such organic ammonium salts, the use of the products of the process for the production of organic ammonium salts in cosmetic formulations for skin care and hair conditioner and hair shampoo, the use of said products for the treatment of fibers, and compositions containing said products for the treatment of hair.

The present disclosure relates to compositions for altering the tone or color of the hair, the compositions comprising at least one amino acid, at least one carboxylic acid, monoethanolamine, and at least one hair coloring agent comprising a direct dye. The disclosure also relates to methods of using the compositions.
