The Verdict: Choose SLES 70% if you want to optimize logistics costs and have high-shear mixing equipment. Choose SLES 28% for smaller-scale production or processes where ease of pouring and immediate solubility are required.
Sodium Lauryl Ether Sulfate (SLES) is a cornerstone surfactant in the global chemical industry. Whether you are formulating high-end shampoos or industrial cleaners, understanding the distinction between the 70% (N70) and 28% (N28) concentrations is vital for production efficiency and cost control.
* SLES 70 vs SLES 28 appearance comparison*
| Feature | SLES 70% (N70) | SLES 28% (N28) |
|---|---|---|
| Appearance | White or pale yellow paste | Colorless to yellowish liquid |
| Active Matter | 70% ± 2% | 28% ± 1% |
| Viscosity | High (Requires heating/mixing) | Low (Easily pourable) |
| Logistics Cost | Low (Less water weight) | High (Higher water content) |
SLES 70% is a highly concentrated “gel-like” paste. It is the industrial standard for large-scale export because you aren’t paying to ship water. SLES 28% is essentially a pre-diluted version of N70, maintaining a liquid state at room temperature, which simplifies the manufacturing process for facilities without specialized dilution tanks.
Handling SLES 70% requires expertise. When diluting N70, it must be added to water under high-speed stirring to prevent the formation of highly viscous “liquid crystals” that are difficult to dissolve. SLES 28% can be added directly to formulations with standard agitation.

Q: Can I substitute SLES 70% for SLES 28% in a recipe?
A: Yes, but you must adjust the water ratio. To get the equivalent of 100kg of SLES 28%, you would use approximately 40kg of SLES 70% and 60kg of additional water.
Q: How should SLES 70% be stored?
A: It should be stored in a cool, dry place. Avoid temperatures above 50°C for prolonged periods to prevent product degradation.
