In both NPnEO and NPnEC, benzene rings are … Nonylphenol ethoxylates in imported textiles iii Abstract Nonylphenol is a priority hazardous substance under the Water Framework Directive (WFD) due to its potential impact upon the aquatic environment. Water quality monitoring continues to detect nonylphenol (NP) and nonylphenol ethoxylate (NPE) in waterways across the UK. These products are NP, nonylphenol ethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenoxyacetic acid (NP1EC) and nonylphenoxyethoxyacetic acid (NP2EC). NPEs can be biodegraded through a mechanism of stepwise loss of ethoxy groups to form lower ethoxylated congeners, carboxylated products and NP.
