What is Sodium 2-ethylhexyl sulfate?
Sodium 2-ethylhexyl sulfate (CAS 126-92-1), also known commercially as Tergemist, is an anionic surfactant.
Where is Sodium 2-ethylhexyl sulfate used?
- Textile and leather processing: improves dye penetration and even distribution of treatment chemicals on fiber surfaces
- Personal care: emulsification and controlled foaming in shampoos, body washes and cleansing products
- Water treatment: dispersant that stabilizes suspensions and prevents scale or particulate buildup in process water
- Printing and packaging: supports ink dispersion and substrate wetting, improving adhesion and print uniformity
- It functions primarily as an emulsifier, dispersant, and wetting agent.
Commercial specifications
- Aqueous solution with active content commonly 35–40%
- Technical grade standard for industrial applications; specifications vary by supplier for purity and pH
- Bulk liquid supply in drums or IBC containers
