Surface active agents. Determination of polyethylene glycol content in nonionic ethoxylated surfactants. HPLC method Ingestion-build-47182 The use of electricity in1 Scope This International Standard specifies a method for the determination of the polyethylene glycol (PEG) content in aromatic and aliphatic non ionic surface active agents of the type R (O C2H4) n OH; where n is the mean ethylene oxide (EO) value. It is applicable to all ethoxylated products soluble in methanol or methanol water mixture. This method applies to PEG concentrations as mass fraction greater than or equal to 0,1 %.
