Gossypol‐oil solution and colour‐fixed oil prepared therefrom are treated with ethanolamine, p‐aminobenzoic acid, urea, and acetic acid. The efficiency of the four additives in removal of gossypol and colour fixed pigments is examined. Ethanolamine and p‐aminobenzoic acid at 0.5 and 1.0% levels of the oil weight result in complete removal of gossypol and superior oil‐colour. The treated oils do not show any sign of colour reversion when subjected to conditions of accelerated storage.
