|Section2= |Section3= }} 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.〔 These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics. Nonylphenol has attracted attention due to its prevalence in the environment and its potential role as an endocrine disruptor and xenoestrogen, due to its ability to act with estrogen-like activity.〔 ==Structure and basic properties== Nonylphenols fall into the general chemical category of alkylphenols.〔Sonnenschein, Carlos, and Ana M. Soto. "An Updated Review of Environmental Estrogen and Androgen Mimics and Antagonists." The Journal of Steroid Biochemistry and Molecular Biology 65.1-6 (1998): 143-50.〕 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. A branched nonylphenol, 4-nonylphenol, is the most widely produced and marketed nonylphenol.〔EPA. 2010. Nonylphenol (NP) and Nonylphenal Ethoxylates (NPEs) Action Plan. February, 2014.〕 The mixture of nonylphenol isomers is a pale yellow liquid, although the pure compounds are colorless. The nonylphenols are moderately soluble in water 〔 but soluble in alcohol. Nonylphenol arises from the environmental degradation of nonylphenol ethoxylates, which are the metabolites of commercial detergents called alkylphenol ethoxylates. NPEs are a clear to light orange color liquid. Nonylphenol ethoxylates are nonionic in water, which means that they have no charge. Because of this property they are used as detergents, cleaners, emulsifiers, and a variety of other applications. They are amphipathic, meaning they have both hydrophilic and hydrophobic properties, which allows them to surround non-polar substances like oil and grease, isolating them from water.〔Soares, A., B.
