Sulfochem™ AS and AES are anionic surfactants that are very soluble in water and have a low vapor pressure. Viscosities range from low (less than 300 centipoise at 25° C) to moderate (less than 12,000 centipoise at 25° C). Sulfochem™ sulfates are generally stable in alkaline pH. They are not compatible with cationics due to the formation of complexes that decrease surfactant effectiveness
