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. Nonylphenols are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail. Nonylphenols can come in numerous structures, all of which may be considered alkylphenols.

Nonylphenol ethoxylate structure

2016-01-01 /ENDOCRINE MODULATION/ Exogenous substances altering the function of the endocrine system and exhibiting adverse health effects on the organism are defined as endocrine disruptors. 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).

Alcohol ethoxylates are often converted to related 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. 51811-79-1 - Ethoxylated nonylphenol phosphate - Similar structures search, synonyms, formulas, resource links, and other chemical information.
