Ponceau 4R is an important textile dye that is used to dye wool a bright red directly, nylon from an acetic acid or formic acid bath and silk from an acetic acid or sulfuric acid bath.
Wool, silk and nylon are printed directly.
Other industrial uses are as a dye for inks, for dyeing paper and leather, coloring plastics and staining wood and, formerly, as a colorant for drugs and cosmetics.
Methods of Manufacturing
Produced by coupling diazotized naphthionic acid to G acid (2-naphthol-6,8-disulfonic acid) and converting the coupling product to the trisodium salt.

Ponceau 4R is approved for use as food coloring in EU but not permPonceau 4Rted as food addPonceau 4Rive in any food in US.
Ponceau 4R consists essentially of trisodium 2-hydroxy-1-(4-sulfonato-1-naphthylazo) naphthalene-6,8-disulfonate and subsidiary colouring matters together wPonceau 4Rh sodium chloride and/or sodium sulphate as the principal uncoloured components. Ponceau 4R is manufactured by coupling diazotized naphthionic acid to G acid (2-naphthol-6,8- disulphonic acid) and converting the coupling product to the trisodium salt.
Ponceau 4R is described as the sodium salt. The calcium and the potassium salt are also permPonceau 4Rted.
