Characteristics and Application :
Nonionic surfactants are surface active agents which do not dissociate into ions in aqueous solutions, unlike anionic surfactants which have a negative charge and cationic surfactants which have a positive charge in aqueous solution. Nonionic surfactants are more widely used as detergents than ionic surfactants because anionic surfactants are insoluble in many hard water and cationic surfactants are considered to be poor cleaners. In addition to detergency, nonionic surfactants show excellent solvency, low foam properties and chemical stability. It is thought that nonionic surfactants are mild on the skin even at high loadings and long-term exposure. The hydrophilic group of nonionic surfactants is a polymerized alkene oxide (water soluble polyether with 10 to 100 units length typically). They are prepared by polymerization of ethylene oxide, propylene oxide, and butylene oxide in the same molecule. Depending on the ratio and order of oxide addition, together with the number of carbon atoms which vary the chemical and physical properties, nonionic surfactant is used as a wetting agent, a detergent, or an emulsifier.

Six surfactants (1 anionic and 5 nonionic), 1 solvent, and 1 antifreeze, used as an adjuvant for surfactants in herbicide formulation were investigated in this study (). All of these chemicals were obtained from the major suppliers of chemicals to a manufacturer of herbicides in Korea (Coseal Co., Goonsan, Korea). More specifically, Honam Petrochemical Co., (Seoul, Korea) provided polyethylene glycol (PEG 300) and monoethylene glycol (MEG); SKC (Seoul, Korea) provided propylene glycol (PG); and KPX Green Chemical Co., (Seoul, Korea) provided polyoxyethylene lauryl amine ether (LN-10), sodium lauryl ether sulfate (SLES), poly(oxyethylene, oxypropylene)glycol block copolymer (PE-61), polyoxyethylene lauryl ether (LE-2), and polyoxyethylene tallow amine (TN-20).
