Replacement of nonylphenol ethoxylates (NPEO) compounds in textile production processes by alkyl ether ethoxylates (AEO) compounds

Textile production could involve the use of nonylphenol ethoxylates (NPEO) compounds for its surfactant properties. Because of the conceivable aquatic toxic and endocrine disrupting effects of NPEO, a more environmentally benign alternative, alkyl ether ethoxylates (AEO) compounds, is adopted to conduct the degumming process. The shift from NPEO to AEO, while giving intended cleaning effect, was demonstrated to result in only a slight change in process and no perceivable impact to product quality.
