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. 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.

T1285 | 127087-87-0. Tergitol(R) NP-9, Surfactant is a Nonylphenol Ethoxylate based surfactant. It is nonionic and provides excellent detergency, outstanding wetting, versatile solubility characteristics and low odor.

Tergitol(R) NP-10, Surfactant is a Nonylphenol Ethoxylate based surfactant. It is nonionic and provides excellent detergency, rinse-ability, and low odor. This product is suggested for use in cleaners & degreasers, prewash spotters and m nonylphenol ethoxycarboxylates under aerobic condition, before being biodegraded to nonylphenol. Shorter ethoxylate chain alkylphenols have greater toxicity than longer ones.

Nonylphenol Ethoxylates are nonionic surfactants produced by the process of ethoxylation on nonylphenol, which consist of phenol bearing a 9 carbon-tail.

September 25, 2014 – EPA proposed a Significant New Use Rule to require Agency review before a manufacturer starts or resumes use of 15 nonylphenols (NPs) and nonylphenol ethoxylates (NPEs). 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.

Xiaoya Ji et. alEcotoxicology and environmental safety, 175, undefined (2019-3-23) The widely used surfactant nonylphenol ethoxylate (NPEO) and its raw material 4-n-nonylphenol (4-n-NP), as well as its degradation products, are recognized as endocrine disrupting chemicals.

In the usual application, alcohols and phenols are converted into R(OC 2 H 4) n OH where n ranges from 1 to 10. Such compounds are called alcohol ethoxylates.

study record(s). Description of key information. Based on the molecular structure of its constituents, NPEO is not considered to have oxidizing properties.

The aim of this work was to gain insight into the effect of ethylene oxide (EO) chains on the properties of a series of nonylphenol ethoxylate (NPE) surfactants. We performed a theoretical study of NPE surfactants by means of density functional theory (DFT) and dissipative particle dynamics (DPD). Both approximations were used separately to obtain different properties. Four NPEs were selected Nonylphenol ethoxylates (NPEs) are surfactants often used in applications that result in their disposal and treatment in wastewater treatment plants (WWTPs).
