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®. Similarly, nonylphenol ethoxylate (NPE) is the most important alkylphenol ethoxylate. NPE accounts for approximately 85% of alkylphenol ethoxylate production (Anonymous 1997).

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).

The common mole ratio forms for detergency are NPE 9 - 12, where the number indicates ethoxylate chain length. The lower number mole ratio products are used as wetting agent whereas the higher moles ratio products are

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 Search results for Nonylphenol Ethoxylate at Sigma-Aldrich.
