Analysis of soaps - Determination of total alkali
content and total fatty matter content
(ISO 685:1975, IDT)
This International Standard specifies a method for the simultaneous determination of the total alkali (l) content and the total fatty matter content of soaps, excluding compounded products.
This method for the determination of total alkali is not applicable to coloured soaps if the colour interferes with
the methyl orange end-point.
