Nonylphenol is raw material for Nonlyphenol ethoxylate which is used in Surfactants. United States, Europe, China and Japan are among the largest manufacturers of Nonylphenol. Nonylphenol ethoxylate structure where n = the average number of moles of ethylene oxide per mole of NP and ranges from 1 to 100.
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.
Mol. formula: 4-Nonylphenol, branched and linear, ethoxylated substances with a linear and/or branched alkyl chain with a carbon number of 9 covalently bound in position 4 to phenol, ethoxylated covering UVCB- and well-defined substances, polymers and homologues, which include any of the individual isomers and/or combinations thereof nonylphenols or nonylphenol ethoxylates may not accurately reflect the identity of those substances. The nine carbon nonyl group may be branched or linear and bind at various locations around the phenol ring (“ortho”, “meta” or “para”). Colorless liquid or white solid with a mild odor. May float or sink in water. A low molecular-weight polymer. Used as a non-ionic surfactant, as an emulsifier, or as a metal cleaner, depending on the degree of polymerization.
The structure of NPs may vary. The nonyl group can be attached to the phenol ring at various locations, usually the 4- and, to lesser extent, the 2-positions, and can be either branched or linear.

The widely used surfactant nonylphenol ethoxylate (NPEO) and its raw material 4-n-nonylphenol (4-n-NP), as well as its degradation products, are recognized as endocrine disrupting chemicals. The USA Environmental Protection Agency (EPA) released an assessment that looked for safe alternatives to NPE …
Nonyl-phenol ethoxylates have much narrower homologue distributions than alcohol ethoxylates (ICI datasheet for Synperonic NP surfactants).

Nonylphenol ethoxylates (NPE) are man-made compounds with the chemical formula (C 2 H 4 O) n C 15 H 24 O. They are compounds of nonylphenol [C 15 H 24 O] with one or more groups of ethoxylates [(C 2 H 4 O)n] attached. The number (n) of ethoxylate groups varies between NPE compounds, imparting different properties to the chemical substance.
