Product Category: High-Active Surfactants / Detergent Raw Materials
Chemical Name: Sodium Laureth Sulphate
Alternative Names: SLES 70 / Sodium Lauryl Ether Sulphate
CAS Number: 68891-38-3
Active Matter: Approximately 70%
Appearance: White to pale viscous paste
Surfactant Type: Anionic
Product Overview
SLES 70% is a concentrated high-active anionic surfactant offering strong detergency, wetting and foaming performance.
Because of its high active content, SLES 70 enables manufacturers to transport and store significantly less water compared with diluted SLES grades.

BASF lists SLES 70 grades in approximately the 68–73% active range, while Stepan supplies 70%-active grades for detergent, personal-care and industrial-cleaning applications.
Applications
- Concentrated detergents
- Dishwashing formulations
- Laundry liquids
- Industrial cleaners
- Vehicle-wash chemicals
- Shampoos and body washes where suitable
- Textile detergents
- Institutional cleaning products
Key Benefits
- High active-matter concentration
- Excellent foaming
