NP9: TERGITOL ™, Type NP-9 pricing 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. As per the Government of Canada (2007), “Nonylphenol ethoxylates (NPEs) are a class of the broader group of compounds known as alkylphenol ethoxylates (APEs). NPEs are high-volume chemicals that have been used for more than 40 years as detergents, emulsifiers, wetting agents and dispersing agents. Nonylphenol polyethoxylate-containing products are used in many sectors, including textile […] Showing posts with label nonylphenol ethoxylate structure. Show all posts.

Types Nonionic Alkylphenol ethoxylates (APEOs – often called alkyphenols or alkylphenyls) are surfactants which have an emulsifying and dispersing action, so they have good D Nonylphenol ethoxylates < 1 CAS #9016-45-9 E Water 60 -100 CAS #7732-18 -5 SECTION III - HAZARDS IDENTIFICATION Emergency Overview Appearance NONYLPHENOL BRANCHED POLYETHOXYLATE. C&L Inventory. Nonylphenol, branched, ethoxylated (> 1 < 2.5 mol EO). C&L Inventory, Registration dossier. study record(s). Description of key information. Based on the molecular structure of its constituents, NPEO is not considered to have oxidizing properties. Electronic structure and mesoscopic simulations of nonylphenol ethoxylate surfactants.

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.

The U.S. Environmental Protec- tion Agency (EPA) issued a Chemical Hazard Information Profile on NP and identified numerous environmental effect data gaps.6 51811-79-1 - Ethoxylated nonylphenol phosphate - Similar structures search, synonyms, formulas, resource links, and other chemical information. 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].
