What is Sodium oleth sulfate?
Sodium oleth sulfate (CAS 27233-34-7) is an ethoxylated anionic surfactant derived from oleyl alcohol.
Where is Sodium oleth sulfate used?
- Personal care: base surfactant in shampoos
- Body washes and facial cleansers: milder skin compatibility than standard alkyl sulfates
- Home care and industrial cleaning: liquid detergents and hard-surface cleaners that boost soil removal and foam stability
- Textile processing: scouring and wetting agent that removes oils and sizing agents from fiber substrates ahead of dyeing
- Emulsion-based formulations: supports stable oil-in-water systems in rinse-off and leave-on formats
- It functions as a primary or co-surfactant, delivering foaming, emulsification, and detergency.
Commercial specifications
- Active matter concentrations commonly 25–35%
- Cosmetic and personal care grades
- Packaging: drums to intermediate bulk containers (IBCs)
