Nonyl-phenol ethoxylates have much narrower homologue distributions than alcohol ethoxylates (ICI datasheet for Synperonic NP surfactants). 880 million pounds (4 mio metric tonnes) of alkyl phenol ethoxylates are used annually throughout the world. 80-85% are sold as nonylphenol ethoxylate (NPE), over 15% as octylphenol ethoxylate, and 1% each as

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.

2 Products. 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.

The U.S. Environmental Protec- tion Agency (EPA) issued a Chemical Hazard Information Profile on NP and identified numerous environmental effect data gaps.6 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.

2018-01-16 · regulations. Nonylphenol ethoxylate (NPE) in all-purpose cleaners was selected as the chemical of concern and priority product combination for the assessment. An all-purpose cleaner is one that works on multiple surfaces and accomplishes many types of cleaning needs; a familiar example of an all-purpose cleaner is Formula 409®.

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 Search results for Nonylphenol Ethoxylate at Sigma-Aldrich.
