Abstract
Surfactant compounds which include an amine ended polyalkylene glycol hydrophile linked to Cto Cmainly hydrocarbyl, particularly composite hydrocarbyl, especially derived from a polymerised fatty acid and/or an aralkyl substituted phenol, hydrophobe, are useful in dispersing solids, particularly active agrochemicals, in aqueous media, or as adjuvants in agrochemical formulations, particularly of water soluble non-selective herbicides. In particular the hydrophobe is derived from polymerised fatty acids, such as dimer and, especially, trimer acids or from aralkyl substituted phenols. Aqueous dispersions using such surfactants can remain stable even with substantial concentrations of electrolyte e.g. in stable agrochemical dispersions including water soluble electrolyte agrochemical, such as glyphosate and/or ammonium sulphate.
