Ht. Rasmussen et al., ANALYSIS OF SODIUM ISETHIONATE IN SOAP AND LYE PROCESS STREAMS BY SUPPRESSED ION CHROMATOGRAPHY, Journal of the American Oil Chemists' Society, 70(7), 1993, pp. 733-734
Suppressed ion chromatography has been used to determine sodium isethi
onate in various soap production process streams at concentrations of
0.1-1.0%. The method was validated by spiking placebo soap and lye pro
cess stream samples. Overall recoveries in soap were 98.5 +/- 2.3% (n
= 24). Recoveries in lye were 98.4 +/- 2.8% (n = 24).
