Nonylphenol salts of Barium as well as calcium have application as heat stabilizers in plastic. Nonylphenol phosphate esters are used to retard flame. Nonylphenol is raw material for Nonlyphenol ethoxylate which is used in Surfactants.
NP can bind to estrogen receptors and elicit estrogenic action in vivo and in vitro. Discovery. NP was first synthesized in the 1940s.

This SNUR, when finalized, will provide EPA the opportunity to review and evaluate any intended new or resumed uses of these chemicals and, if necessary, take action to limit those uses. Alkylphenol ethoxylates are used as surfactants, and in the environment, such as nonylphenol and octylphenol (Ying et al., 2002).
REPORT
Nonylphenol is one of the most abundant alkylphenol ethoxylate derivatives, being detected in food products. Nonylphenol Ethoxylates Nonylphenols are a family of closely related organic compounds called alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers.[2] These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are Search results for Nonylphenol Ethoxylate at Sigma-Aldrich. Compare Products: Select up to 4 products. *Please select more than one item to compare 4-nonylphenol (para-nonylphenol) with a varied and undefined degree of branching in the alkyl group, while very little straight chain nonylphenol is present (EU-RAR 1998). Similarly, nonylphenol ethoxylate (NPE) is the most important alkylphe-nol ethoxylate.

However, their effects on various nuclear hormone receptors have not been thoroughly examined. industries [3]. Their molecular structure contains repeated EO units as hydrophilic groups. Surfactant properties depend on EO length and type of hydrophobic combined groups. Nonylphenol ethoxylate (NPE) surfactants have been used in EO range from 4 to 70 units.
