DIN EN ISO 8799
Surface active agents - Sulfated ethoxylated alcohols and alkylphenols - Determination of content of unsulfated matter (ISO 8799:2009); German version EN ISO 8799:2009

Title (German)

Grenzflächenaktive Stoffe - Sulfatierte ethoxylierte Alkohole und Alkylphenole - Bestimmung der unsulfatierten Anteile (ISO 8799:2009); Deutsche Fassung EN ISO 8799:2009

Overview

This standard specifies a method for the determination of the content of unsulfated matter present in ordinary commercial neutralized products of sulfation of ethoxylated alcohols or alkylphenols [alkyl oxyethylene sulfates (ethoxylated alcohol sulfates) or alkylphenol oxyethylene sulfates (ethoxylated alkyphenol sulfates)] containing an average of not more than 20 oxyethylene groups per molecule. From a methanolic solution of the test portion, the unsulfated matter is separated on an ion-exchange column and recovered from the eluate by evaporation and weighing of the residue. The Standard has been prepared by Technical Committee CEN/TC 276 "Surface active agents", the secretariat of which is held by AFNOR (France), in collaboration with Technical Committee ISO/TC 91 "Surface active agents". The responsible German Committee is Working Committee NA 062-05-62 AA "Analytik von Tensiden" ("Analytics of surfactants").
