Two type of surface active agents anionic and nonionic were prepared from locally raw materials: Fatty acids (Iauric and palmitic) reacted with poly ethylene glycol (PEG) 400. 600 in case of nonionic surfactants preparation and fatty acids reacted with potassium hydroxide and calcium oxide in case of anionic surfactants preparation. Locally prepared nonionic surfactants were identified using IR and Massspectroscopy. Physico-chemical properties were assessed such as HLB, critical micelle concentration CMC. free acidity or alkalinity and solubility in different solvents to give prediction of the best use in pesticide formulation. Results obtained indicated that nonionic surfactants PEG 600 ML were miscible in water while. the other nonionic surfactants gave emulsion in water. and showed different solubility in xylene and acetone. 0n the other hand divalent salts (calcium palmitate and Iaurate) were insoluble in water or any solvents, therefore it is unsuitable to use in formulation . while, mono valent (potassium Iaurate and potassium palmitate) were soluble in water. Also the results showed that locally prepared surfactants decreased the surface tension of water , nonionic surfactants PEG 400 ML was the most in decreasing the surface tension followed by PEG 600 ML. on the other hand pt-laurate (ionic surfactant) decreased the surface tension to 29.1 dynelcm, this finding indicated that these surfactants could be used as wetting and spreading agents. Also the result indicated that Iaurate esters have HLB 10-12, palmitate esters have HLB 6-8, ionic surfactants (pt-Iaurate and pt-palmitate) have HLB 12-18 . therefore they were suitable to use as suspending . wetting and spreading agents.
