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
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. The critical micelle concentration 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.
They are used mainly in industrial and institutional cleaning, textile and leather processing, metal- working fluids, agrochemicals, emulsion polymerisation, paints, and in a host of smaller appli-cations such as oil field chemicals and paper production.

Ethoxylation is commonly practiced, albeit on a much smaller scale, in the biotechnology and pharmaceutical industries to increase water solubility and, in the case of pharmaceuticals, circulatory half-life of non-polar organic compounds. Vanillin ethoxylate (VAEO) is a novel substitute for NPEO and is quite similar to NPEO in structure; there is a risk that it has similar endocrine disrupting effects to NPEO.

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. The term “nonylphenol” represents a large num-ber of isomeric compounds, varying in the point of attachment of the nonyl group to the phenol molecule, and in the degree of branching in the nonyl moiety. Commercially produced nonylphenols are predominantly NPEs (nonylphenol ethoxylates) break down in the environment into nonylphenol (NP), one of the most notorious examples of persistent, bioaccumulative and toxic chemicals (PBTs). Widely recognized for extreme aquatic toxicity to fish and wildlife, NPEs and NP may also threaten the health of the developing fetus and young children.
Synonym: NP-2EO technical. Empirical Formula (Hill Notation): C 19 H 32 O 3. Molecular Weight: 308.46. EC Number: 200-662-2. 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.

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. referring to the branched nonylphenol. CASRN 84852-15-3 corresponds to the most widely produced nonylphenol, branched 4-nonylphenol (referred to herein as NP). Note that NP is not a single chemical structure. It is a complex mixture of highly branched nonylphenols, largely mono-substituted in the ETHOXYLATED NONYLPHENOL is a polyether. May react exothermically with strong oxidizing agents.
