Scope: This standard specifies the method for the determination of residual monochloroacetic acid (salt) and dichloroacetic acid (salt) in surfactants by liquid chromatography. This standard applies to surfactants produced from monochloroacetic acid or sodium monochloroacetate, such as: alcohol phenol ether carboxylate, undecyl imidazoline carboxylate, fatty alkyl dimethyl betaine, fat Determination of residual monochloroacetic acid (salt) and dichloroacetic acid (salt) content in amidopropyl dimethyl betaine and other products. When the content of monochloroacetic acid (salt) and dichloroacetic acid (salt) in the sample exceeds the range of the standard working curve, it is necessary to increase the concentration of the standard solution or to dilute or reduce the sample for determination.
