Sodium Laureth Sulfate 70% (SLES Paste)
Concentrated 70% active SLES paste for large-volume manufacturers — significantly lower freight cost per kg of active vs. 28% liquid grades.
Product Overview
Sodium laureth sulfate 70% (SLES 70%) is the concentrated paste form of sodium laureth sulfate, containing 70% active surfactant by weight compared to 28% in the standard liquid grade. It is produced by the same ethoxylation-sulfation-neutralization process as SLES 28%, but with reduced water content.
Texas-Chem supplies SLES 70% paste in heated drums and totes. The paste requires storage and handling above 40°C to remain pumpable. Large-volume manufacturers who dilute on-site benefit from significantly lower freight costs per kilogram of active surfactant compared to shipping the 28% liquid grade.

SLES 70% paste is a mild irritant. Avoid contact with eyes. The paste requires heating above 40°C for handling — use appropriate heated equipment and insulated lines. Avoid overheating above 60°C which can cause degradation. Review SDS before use.
Frequently Asked Questions
Why use SLES 70% paste instead of SLES 28% liquid?
SLES 70% paste contains 2.5x more active surfactant per kilogram than SLES 28% liquid. For large-volume manufacturers, this means 60% less freight volume per unit of active, significantly reducing shipping costs. The trade-off is the need for heated storage and handling equipment.
What equipment is needed to handle SLES 70% paste?
SLES 70% paste requires heated storage tanks (maintained above 40°C), heated transfer lines, and heated pumps. Standard stainless steel or HDPE equipment is suitable. The paste becomes a pourable liquid above 40°C and can be pumped and metered like a liquid at that temperature.
How do I dilute SLES 70% paste to 28% for formulation?
To dilute SLES 70% to 28% active: mix 1 part SLES 70% with approximately 1.5 parts warm water (50-60°C) with gentle agitation. The resulting solution will be clear to slightly hazy and can be used directly in formulations. Avoid adding cold water to hot paste as this can cause lumping.
What is the minimum order quantity for SLES 70%?
Texas-Chem supplies SLES 70% in heated drums (55-gal) and heated totes (275-330 gal). Contact us for minimum order quantities, lead times, and bulk tanker availability for very large volumes.

Sodium Laureth Sulfate 70% (SLES Paste) vs. Alternatives
SLES 70% paste is the freight-efficient form of SLES for large-volume manufacturers. Here is how it compares to the standard 28% liquid grade.
| Attribute | Sodium Laureth Sulfate 70% (SLES Paste) | SLES 28% Liquid | SLS Powder |
|---|---|---|---|
| Active Content | 70% by weight | 28% by weight | 90-95% by weight |
| Physical Form | Paste — solid below 40°C | Liquid — pump-ready at ambient | Powder/needles |
| Freight Cost per kg Active | Low — 2.5x more active | Higher — 60% more freight volume | Lowest — highest active content |
| Handling Equipment | Heated tanks and lines required | Standard ambient equipment | Dry handling — dust control |
| Best For | Large-volume manufacturers | Small to medium formulators | Dry blend and powder products |
