A precursor used for the production of tensides

Nonylphenol (NP) is a high production volume chemical, used for nonylphenol-ethoxylates (an important group of tensides).

The potential of NP for environmental pollution has been known for a long time, with negative environmental effects shown as early as the late 1970s.

This was followed by voluntary and regulatory reduction measures.

In Germany a phase out of ethoxylates (especially in washing and cleaning products) happened mainly between 1986 and 1992 (in the EU between the years 1995 and 2000). Total usage of NP in this time frame dropped around 85%.

Since 2003 NP is highly regulated in the EU and was classified as substance of very high concern (SVHC) in 2012. Nevertheless, NP is still produced in high amounts.

Considering the potential for endocrine disruption NP is highly relevant for human biomonitoring.
