Sodium lauryl polyoxyethylene ether sulfate

Sodium lauryl polyoxyethylene ether sulfate (CAS 9004-82-4), commercially known as SLES, is an anionic surfactant.

Where is Sodium lauryl polyoxyethylene ether sulfate used?

• Personal care: primary foaming and cleansing agent in shampoos, body washes, liquid soaps and facial cleansers
• Textile processing: scouring and wetting agent that removes oils, waxes and sizing agents before dyeing or finishing
• Leather processing: degreasing hides during beam house operations
• Industrial cleaning: hard surface cleaners and laundry detergents
• It delivers high-foaming, emulsifying and degreasing performance at competitive cost.

Good to know: Grades are differentiated by ethoxylation degree, typically 2 EO or 3 EO, which affects mildness and cold-water solubility.

Commercial specifications

• 70% active content
• 28% active content for easier handling or lower viscosity
