The risks and alternatives of APEO and NPEO in textiles part 2

The risks and alternatives of APEO and NPEO in textiles (2/2) Introduction Fish toxicity of APEOIn the first part of this article the risks of the use of APEO products were shown. The second part gives information about product alternatives, global regulations and environmental advantages after the ban of APEO in Europe. Moreover, the results of the Greenpeace research about nonylphenol ethoxylate residues in textiles are discussed opposite the joined efforts of the ZDHC project. Alternatives to replace APEO/NPEO In most applications, APEOs can be replaced by linear alcohol ethoxylate surfactants, which are readily biodegradable. However, direct replacement can be difficult in some situations.

chemistry of surfactants

In contrast to the alkylphenols, nonionic surfactants which are based on ethoxylations, are not composed of a single substance, but they are mixtures of molecules with different numbers of ethylene oxide building blocks. There are large differences during the chemical reaction of a fatty alcohol with ethylene oxide. AP-reactivityAlkyl phenols possess the highest reactivity, which made them so interesting for the chemical industry. Because of the high reactivity it is possible (more…)
