Dispersant NNO – Anionic Surfactant
What is Dispersant NNO, and Why is it Called an Anionic Surfactant? Dispersant NNO, or Sodium Naphthalene Sulfonate Formaldehyde Condensate, is a chemical powder used to improve the behavior of materials like concrete, dyes, or pesticides. It’s called an anionic surfactant because it’s a surface-active agent (surfactant) with a negative charge (anionic). Think of it…
