4-Nonylphenol und seine Ethoxylate sind in der EU in zahlreichen Verwendungen, wie z.B. dem Einsatz in Wasch- und Reinigungsmitteln verboten.4-nonlyphenol ist ein prioritär gefährlicher Stoff nach der EU-Wasserrahmenrichtlinie (WRRL). 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.

Mol. formula: 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 nonylphenols or nonylphenol ethoxylates may not accurately reflect the identity of those substances. The nine carbon nonyl group may be branched or linear and bind at various locations around the phenol ring (“ortho”, “meta” or “para”).
Many products are non-alkyl phenol ethoxylate (APE) based, and readily biodegradable with low aquatic toxicity. Dow surfactants enable: Improved environmental profile, cleaning and wetting performance in household, industrial and institutional cleaning product formulations
used anti-NPE messages in their adver- tising. The U.S. Environmental Protec- tion Agency (EPA) issued a Chemical Hazard Information Profile on NP and identified numerous environmental effect data gaps.6 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. The USA Environmental Protection Agency (EPA) released an assessment that looked for safe alternatives to NPE … lating to restrictions on the marketing and use of nonylphenol and nonylphenol ethoxylates for those uses, which have an impact on the aquatic environment.

SAFETY HAZARDS. Explosivity. Not expected to be explosive based on its structure. Nonylphenols (NP) and nonylphenol ethoxylates (NPEs) are used as surfactants in detergent formulations, wool, metal, textile and leather processing, and as 8 Mar 2015 nonylphenol ethoxylates and nonylphenol in cosmetic products in the I'm not sure what about the structure would cause that conclusion to be The hydrophilic group of nonionic surfactants is a polymerized alkene oxide ( water soluble polyether with 10 to 100 units length typically). They are prepared by Alternatives for Nonylphenol Ethoxylates 5.2 Effects of Alkyl Chain Structure .
They are used extensively in epoxy formulation in North America but its use has been phased out in Europe. These compounds are also precursors to the

Nonylphenol ethoxylates (NPEs) represent the main product type in this group. 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.

NPE accounts for approximately 85% of alkylphenol eth-oxylate production (Anonymous 1997). 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].
