Sodium laureth-2 sulfate

Sodium laureth-2 sulfate (CAS 3088-31-1), also marketed as Tergentol, is an ethoxylated anionic surfactant used in personal care and industrial processing.

Where is Sodium laureth-2 sulfate used?

• Personal care: primary surfactant in shampoos, body washes and liquid cleansers
• Textile processing: scouring and wetting agent that removes oils, sizing agents and contaminants from fiber before dyeing or finishing
• Leather processing: degreasing baths where emulsification of natural fats is critical to hide preparation
• Paper industry: pulp wetting and surface treatment formulations where uniform dispersion is required
• It delivers foaming, emulsification and detergency where mildness and lather performance are both required.

Good to know: It produces stable, dense foam with lower irritation potential than non-ethoxylated sulfates. Cosmetic grades meet specifications relevant to personal care manufacturing.

Commercial specifications

• Active matter concentrations commonly 25% to 70%
• Drum and IBC packaging standard for industrial volumes
