Where does nonylphenol come from?

Nonylphenol arises from the environmental degradation of nonylphenol ethoxylates, which are the metabolites of commercial detergents called alkylphenol ethoxylates. NPEs are a clear to light orange color liquid. Nonylphenol ethoxylates are nonionic in water, which means that they have no charge.

What are nonylphenol ethoxylates?

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.

What is the chemical np9?

Polyoxyethylene Nonylphenol (NP-9) is a surfactant. A surfactant, by the way, is a substance that lowers the surface tension between two liquids or a liquid and a solid, giving nonylphenol ethoxylate the ability to disperse one form of matter into another.

What products contain nonylphenol ethoxylate?

Commonly used in:

  • Household paints, colorants and wood finishes.
  • Clothing and textiles.
  • Paint and stain removers.
  • Surface and drain cleaners.
  • Indoor pesticides.
  • Food packaging (contains related chemicals)
  • Footwear, toys and games (contains 4-nonylphenol)

What are Nonylphenols used for?

Nonylphenols (NPs) 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 (Soares et al., 2008).

What type of surfactant is NP9?

nonionic surfactant
Np-9 is a nonionic surfactant that is soluble in water and most chlorinated and polar solvents. It is chemically stable in the presence of dilute acids, bases and salts.

What does a surfactant do?

The surfactant reduces the surface tension of water by adsorbing at the liquid–gas interface. They also reduce the interfacial tension between oil and water by adsorbing at the liquid–liquid interface. CPE is the first extraction method in which a surfactant has been used.

What is a surfactant in medical terms?

Surfactant: A fluid secreted by the cells of the alveoli (the tiny air sacs in the lungs) that serves to reduce the surface tension of pulmonary fluids; surfactant contributes to the elastic properties of pulmonary tissue, preventing the alveoli from collapsing.

Is NP9 a foaming agent?

Foaming agent: it accelerates foam development in products.
