Surface active agents. Determination of N-(3-dimethylaminopropyl)-alkylamide content in alkylamidopropylbetaines. Gas chromatographic method Ingestion-build-50790 This part of ISO/IEC 197961 Scope This European Standard specifies a method for the determination of the content of free N (3 dimethylaminopropyl)alkylamides (amidoamine) in alkylamidopropylbetaines, expressed in grams per 100 g of product. This method is applicable in the range between 0,02 g and 1,0 g of amidoamine per 100 g of product.
