What does NP9 stand for?

Nonoxynol-9, sometimes abbreviated as N-9, is an organic compound that is used as a surfactant. It is a member of the nonoxynol family of nonionic surfactants. N-9 and related compounds are ingredients in various cleaning and cosmetic products. It is widely used in contraceptives for its spermicidal properties.

What is nonylphenol used for?

Nonylphenol is used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers.

Is NP9 biodegradable?

Completely water soluble and biodegradable, there’s also no need for customers to reformulate. It can simply be used as a direct drop-in for NP9 or NP10. Produced in large volumes and widely used in detergents and cleaning products, NPEs are thought to be toxic to aquatic organisms.

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.

Is NP9 toxic?

Acute toxicity, Category 4 (Oral) Harmful if swallowed.

Is nonylphenol banned?

Nonylphenol ethoxylates to be banned in imported clothing and textiles. The European Union’s REACH Chemicals Committee has voted unanimously to implement a ban on imported textiles and clothing containing nonylphenol ethoxylates (NPEs) above a maximum permitted level of 0.01 % m/m.

Is nonylphenol toxic?

Nonylphenol is a toxic xenobiotic compound classified as an endocrine disrupter capable of interfering with the hormonal system of numerous organisms. Nonylphenol ethoxylates reach sewage treatment works in substantial quantities where they biodegrade into several by-products including nonylphenol.

Is np9 flammable?

Non-flammable in presence of shocks. Explosion Hazards in Presence of Various Substances Risks of explosion of the product in presence of mechanical impact: Not available.

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 surfactant means?

Surfactant, also called surface-active agent, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties. Other surfactants that are more lipophilic and less hydrophilic may be used as defoaming agents, or as demulsifiers.

What is surfactant in biology?

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.

What kind of surfactant is NP-9 in water?

BC Surfactant NP-9 (Nonylphenol Ethoxylate) BC Surfactant NP-9, or nonylphenol ethoxylate, is used primarily, as the name suggests, as a nonionic (having no electric charge in water) surfactant.

What are NP / NPES and what are their uses?

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.

Where are ethoxylated isomers of nonylphenol NP-9 found?

The ethoxylated isomers of nonylphenol (NPEs, NP-9) are one of the main active ingredients present in nonionic surfactants employed as herbicides, cosmetics, paints, plastics, disinfectants and detergents. These chemicals and their metabolites are commonly found in environmental matrices.

How many NPs are in the proposed SNUR?

This action is part of EPA’s work to ensure chemical safety in order to protect human health and the environment. Q5. How many chemicals are in the proposed SNUR? There are 15 NP/NPE chemicals in this proposed SNUR; four NPs and 11 NPEs.
