SLES 70% in Liquid Cleaning Products: Why Active Matter Matters

When buyers compare Sodium Laureth Sulfate products, the first specification they usually notice is active matter. For liquid detergents, shampoos and hand wash products, SLES 70% remains one of the most common commercial grades.

The reason is not simply that a higher concentration means “stronger cleaning.” Active matter affects how much surfactant is actually introduced into the formula, how the product is transported and stored, and how easily the final surfactant concentration can be adjusted.

Why Is 70% Active Matter Common?

SLES is available in different concentrations, but SLES 70% offers a practical balance between concentration and handling.

Compared with more diluted grades, less water is shipped with the product. This can reduce storage volume and transportation demand, especially for customers purchasing in drums, IBCs or container quantities.

At the same time, the material can still be incorporated into many liquid surfactant systems after suitable dilution and mixing.

Active Matter Affects Formulation Dosage

The SLES concentration on the raw material specification should always be considered when calculating dosage.

For example, adding 10 kg of SLES 70% does not mean that 10 kg of active surfactant enters the formulation. At 70% active matter, the actual amount of active SLES is about 7 kg.

This becomes important when manufacturers compare suppliers or replace one concentration with another. Comparing raw material dosage alone can easily give a misleading result.

Foam and Viscosity Are Not Controlled by SLES Alone

SLES is widely used because it provides good detergency and foam performance in aqueous cleaning systems. However, final foam, viscosity and mildness depend on the complete surfactant system.

In many formulations, SLES is combined with materials such as CAPB, betaines or nonionic surfactants. Salt may also be used to adjust viscosity, but the response depends on surfactant ratio, electrolyte level and other ingredients in the formulation.

This is why replacing one SLES grade with another should usually be followed by a small formulation check rather than a simple one-to-one substitution.

What Should Buyers Check When Sourcing SLES 70%?

Besides active matter, buyers commonly review appearance, pH, sodium sulfate content and unsulfated matter. Batch consistency is also important for manufacturers that need stable viscosity and processing behaviour from one production run to another.
