The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the … 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 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 The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents.The information in CAMEO Chemicals comes from a variety of data sources.

Nonylphenol Ethoxylates have various molecular weights and properties. The properties of a particular Nonylphenol Ethoxylate depend upon the number of ethoxylate groups that are attached (the number of ether linkages along the chain), which can vary from just a few up to about one hundred.

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.

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.

Such compounds are called alcohol ethoxylates. 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.

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).
