Alkylphenol ethoxylates (APEOs – often called alkyphenols or alkylphenyls) are surfactants which have an emulsifying and dispersing action, so they have good wetting, penetration, emulsification, dispertion, solubilizing and washing characteristics. This makes them suitable for a very large variety of applications: they’ve been used for over 50 years in a wide variety of products. In the textile industry, they are used in detergents and as a scouring, coating or waterproofing agents, in printing pastes and adhesives, and in dyeing. The most important APEO or alkylphenol ethoxylates for the textile industry are NPEO (nonylphenol ethoxylates) and OPEO (octylphenol ethoxylates) due to their detergent properties, but there are a big family. About 90% of the produced APEO are in fact NPEO.
The three critical issues in making APEOs and NPEOs in the environment of particular concern are:
- They are everywhere. They’re in receipts, canned foods and couches, paint and spot cleaners. They’re…
