ABSTRACT:
The pink color content often produced in products such as amine salts, amine oxides, betaines, quaternary ammonium compounds or other compounds derived from long chain alkyl amines is eliminated by treating the products with trace amounts of a bleaching agent. Heating of the treated amine at relatively low temperatures for a short period of time enhances the effectiveness of the bleaching agent. Long chain alkyl amines having a pink color may be similarly treated.
