Although saponification per se is not required, it may be useful to prevent the decomposition of the alkyl sulfate when mixing the components in the Kneaders use a small amount of an alkali metal hydroxide at elevated temperature. A small part of the palmitic and / or stearic acid can be saponified. However, care should be taken to ensure that no more than 50% of the fatty acid is saponified.
