SLES Dilution System

Application

Sodium Laureth Sulfate (SLES) is used at a concentration of 26% for the production of shampoos, gels, soaps and other cleaning products.
SLES is sold either at a concentration of 70% or already diluted at 26 %.
The following system offers the production of SLES with the adequate concentration of 26%, based on the concentrate and network water.
The graph explains why the process is carried out with the indicated concentration of SLES.
If the concentration exceeds 27%, the viscosity greatly increases and affects the right handling of the product.
The purchase of the concentrated raw material instead of a dissolved to 26% product allows
savings in storage and transport costs.

Design and features

The concentration of the various ingredients is controlled by a PLC, frequency converters and flowmeters that regulate the pumps.
The performance range is from 4000 up to 10000 kg/h.
A conductivity tester after the mixer controls if the product is correct or not. Valves allow the product to pass to the production line or to drain.
The valves required are automated butterfly valves with pneumatic actuator and C-TOP control unit.
The system is supplied with a tank for preservatives.
As an option, a pH meter can be installed to control the concentration of the preservative and desinfectant.
