Physicochemical characterization of nonionic surfactants in oil-in-water (O/W) nano-emulsions for new pesticide formulations

Physicochemical characteristics of pre-formulation concentrates of an emulsion system of LFAMEs/APG: organosilicone/water were determined. The surfactants used were octyl/decyl polyglucosides (short-chain APG; SAPG) and dodecyl/tetradecyl/hexadecyl polyglucosides (long-chain APG; LAPG). Alkyl chain...
