When purchasing SLES 70%, buyers often compare price and concentration first. However, the “70%” designation alone does not provide a complete picture of product quality.
Active matter, sodium sulfate, unsulfated matter, colour, pH and batch consistency may all affect formulation calculations and product performance. Understanding these parameters helps buyers determine whether the product meets their formulation and production requirements.
What Does SLES 70% Mean?
SLES stands for Sodium Lauryl Ether Sulfate, an anionic surfactant widely used in liquid detergents, household cleaners, personal care products and industrial cleaning formulations.
SLES 70% is a concentrated paste grade containing approximately 70% active surfactant matter. The exact specification may vary between suppliers, so buyers should review the complete TDS and batch COA rather than relying only on the product name.
In many cleansing formulations, SLES is combined with amphoteric surfactants such as Cocamidopropyl Betaine (CAPB) to adjust foam, viscosity and the overall mildness of the surfactant system.
Active Matter
Active matter indicates the concentration of effective surfactant in the product. It directly affects raw-material dosing, formulation cost and finished-product performance.
Consistent active matter helps manufacturers maintain stable detergency and foaming performance without frequently adjusting the formulation between batches.
When comparing products, buyers should check both the specified range and the actual batch result shown on the COA.
Sodium Sulfate
Sodium sulfate is an inorganic component that may remain following the sulfation and neutralization stages of production. It does not contribute to the cleansing performance of SLES.
Its content may affect active-material calculations, the salt balance of the formulation and, in some systems, viscosity or clarity. Buyers should therefore review the specified maximum value and monitor its consistency between batches.
Sodium sulfate should be evaluated together with active matter and the requirements of the final application.
Unsulfated Matter
Unsulfated matter generally refers to organic components that have not been converted into the intended sulfate surfactant.
Its level can reflect raw-material composition and reaction control. Because these components do not perform in the same way as the target active surfactant, unsulfated matter should remain within the approved specification.
This parameter is most useful when reviewed together with active matter and batch consistency.
Colour, Appearance and pH
SLES 70% is commonly supplied as a white to pale yellow viscous paste. Colour consistency is especially important for white, transparent or lightly coloured finished products.
Buyers should check for unexpected darkening, contamination, separation or changes in texture during incoming inspection.
The pH value can also provide information about product condition and neutralization control. However, pH results should only be compared when the test concentration and method are the same.
