Product: Sodium Lauryl Ether Sulfate (SLES)

CAS No.: 9004-82-4 (n=1-4) / 68891-38-3 (n=2-3)
Hazard Class: 9 (Miscellaneous)
UN No.: 3082 (Environmentally Hazardous)
Appearance: Clear to pale yellow viscous liquid (70% solution) / White paste (90% active)

Description: Sodium lauryl ether sulfate is produced through ethoxylation of lauryl alcohol followed by sulfation and neutralization, serving as the dominant anionic surfactant in personal care (shampoos, 40% market share) and household cleaners (dish liquids). The ethylene oxide units (n=1-4) balance foaming power (higher EO=gentler but less foam) and viscosity (thickens with salt).
