Blends of alcohol ethoxysulfates (AES) and alcohol ethoxylates (AE) at high active matter content (90%) have been prepared. These blends contain no solvents other than water and have sufficiently low viscosities enabling the pumping of them from storage vessels to mix tanks. In addition, they may be diluted into aqueous solutions with less gel formation tendencies than shown by AE or AES alone. Specific AE/AES blend ratios, alkyl and polyoxyethylene chain lengths are important selection parameters for achieving desired rheological properties.
