DESCRIPTION

EN 12582


EN 12582 Surface active agents - Determination of the polyethylene glycol content according to molar mass in non-ionic surface active agents (ethoxylated) by HPLC/ELSD - This European 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) p OH; where p 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 %.
