Nonylphenols are a family of closely related organic compounds composed of phenol bearing a 9 carbon-tail. Nonylphenols can come in numerous structures, all of which may be considered alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. [2] .

May 17, 2024 · NP/NPEs, also known as nonylphenols and nonylphenol ethoxylates, are nonionic surfactants, or detergent-like substances, with uses that lead to widespread release into aquatic environments. NP/NPEs are highly toxic to aquatic life.

The meaning of NONYL is an alkyl radical C9H19 derived from a nonane; especially : the normal radical CH3(CH2)7CH2—.

A nonyl group is defined as a specific alkyl group consisting of nine carbon atoms, which was confirmed in the isomeric structure of nonylphenol through GC-MS and NMR analysis in environmental pollutant studies.

Feb 13, 2025 · NPEs are nonionic surfactants that are used in a wide variety of industrial applications and consumer products. Many of these, such as laundry detergents, are “down-the-drain” applications. Some others, such as dust-control agents and deicers, lead to direct release to the environment.

Nonylphenol is used to produce tris(4-nonyl-phenyl) phosphite (TNPP). TNPP is also used as a stabilizer in plastic food packaging. Although it does contain residual nonylphenol, TNPP has been approved for this use by the Food and Drug Administration (FDA).

Aug 15, 2010 · Nonylphenol, for example, is a surfactant compound and it sorbs onto sediments after discharge from sewage works and is thought to be involved in the endocrine disruption of aquatic organisms.

Define nonyl. nonyl synonyms, nonyl pronunciation, nonyl translation, English dictionary definition of nonyl. adj. Relating to or being a hydrocarbon unit, C9H19, that can occur as a substituent in an organic compound or as an ion or radical.

Nonylphenol is an organic compound of the wider family of alkylphenols. It is a product of industrial synthesis formed during the alkylation process of phenols, particularly in the synthesis of polyethoxylate detergents. Because of their man-made origins, nonylphenols are …

Aug 9, 2010 · Nonylphenol (NP) and nonylphenol ethoxylates (NPEs) are produced in large volumes, with uses that lead to widespread release to the aquatic environment. NP is persistent in the aquatic environment, moderately bioaccumulative, and extremely toxic to aquatic organisms. NP’s main use is in the manufacture of NPEs.
