Product Details
By successive extraction, separation, evaporation, redissolution, and filtration through an ion-exchange resin the contents of sodium chloride, anionic-active matter, polyglycol, and polyglycol sulfate are determined. From the content of anionic surface active agent (alkylether sulfate) and the anionic surface active matter content determined by two-phase titration, the mean relative molecular mass is estimated.
