ANIONIC SURFACTANT

Description

Anionic surfactants have a negative charge and will readily ionize when mixed with water. Anionic surfactants are strong detergents and excellent wetting agents. However, a disadvantage of anionic surfactants is the potential of the molecules to interact with other ions in the spray solution, such as calcium, magnesium, and ferric ions, rendering them unavailable to function as an activator adjuvant. The negative charge may also cause anionic surfactants to interact with the herbicide, which may result in an insoluble herbicide complex.

Agricultural Uses

An anionic surfactant is a type of ionic surfactant used for coating fertilizer materials to improve fertilizer quality. Commonly employed anionic surfactants are sulphonates, particularly alkyl aryl sulphonates, and their action is due primarily to their hydrophobic nature, Sodium stearate 17(C₁₇H₃₅COO^-Na⁺)s an example of an anionic surfactant.
