PURIFICATION OF SECONDARY (2, 3) ALKYL SULFATE SURFACTANTS

Secondary (2, 3) alkyl sulfate surfactants contaminated with inorganic sulfates such as sodium sulfate are washed with water at temperatures at or below the Krafft temperatures of said surfactants. The resulting, purified secondary alkyl sulfate surfactants are especially useful in the manufacture o...

Summary:Secondary (2, 3) alkyl sulfate surfactants contaminated with inorganic sulfates such as sodium sulfate are washed with water at temperatures at or below the Krafft temperatures of said surfactants. The resulting, purified secondary alkyl sulfate surfactants are especially useful in the manufacture of homogeneous liquid or gel detergent compositions. Des tensioactifs sous forme de sulfates d'alkyle (2, 3) secondaires contaminés par des sulfates inorganiques tels que du sulfate de sodium sont lavés avec de l'eau aux températures Krafft desdits tensioactifs, ou au-dessous desdites températures. Les tensioactifs constitués de sulfates d'alkyle secondaires purifiés qui en résultent sont particulièrement utiles dans la production de compositions détergentes homogènes liquides ou en gel.
