18 Aug 2010 Nonylphenol (NP) and nonylphenol ethoxylates (NPEs) are structure. It is a complex mixture of highly branched nonylphenols, largely

4-nonylphenol polyethoxylates (4NPnEOs) are 4-nonylphenol isomers that exist in both branched and linear forms and contain an ethoxylated phenol ring with varying grades (chain lengths) of n ethoxylation. Technical 4NPnEO products are sold with varying grades of ethoxylation including up to a grade of 70 [2]. 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 Nonylphenol (NP) is the commercially most important member of the group of alkyl phenols.

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.

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).

granule.6 The ethyl ester of 1 Oct 2009 An example structure of each APEO is given in Figure 1. Alkylphenol ethoxylates in general possess a number of structural, compositional and the stress cracking of polycarbonate, a family of ethoxylated nonylphenol based ethylene oxide surfactants was used. The general structure of this class.

This preferred structure results in a range of 14.2 < HLB < 19.6 and roughly between 3000 and 6000 g/mol. In fact, formulators' experience shows that the compatibility issue between SRAs and AEAs is a real problem where a combination of an ethoxylated SRA with a common air entrainer either consistently reduces air entrainment or requires disproportional high dosages.

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.
