Surfactant

Action/Use:
  • Adjuvant
Use: Most pesticide adjuvants may be considered surface active agents. These materials can be classed as nonionic, anionic, cationic, and amphoteric. Most emulsifying agents are nonionic; wetting agents and detergents are primarily anionic. Cationic surfactants exhibit a net positive charge in solution and are not widely used in agricultural chemicals. Amphoterics have both anionic and cationic charges and are also seldom used in agricultural chemicals. Many terms designate particular surface activities; these are often related. See also Activator; Adjuvant; Deflocculator; Detergent; Emulsifier/Dispersant; Foam Suppressant; Spreader; Wetting Agent.
