Kemsurf DSA
Product Category: Anionics
Sodium Lauryl Sulphate (Sodium Lauryl Sulfate)
INCI Name: Sodium Lauryl Sulfate
Kemsurf DSA is an anionic surfactant based on sodium lauryl sulphate, supplied as an aqueous solution. It provides excellent detergency, foaming, and wetting performance, making it suitable for a wide range of industrial and personal‑care applications.
Kemsurf DSA delivers strong surface activity, enabling efficient removal of oils, greases, and particulate soils. It produces rich, stable foam and offers reliable cleaning performance across a variety of formulation systems.
The product is compatible with other anionic and non‑ionic surfactants and exhibits good formulation flexibility. It performs well in mildly alkaline conditions, although, like typical alkyl sulphates, it may hydrolyse under strongly acidic conditions. Kemsurf DSA is also readily biodegradable, supporting its use in environmentally conscious formulations.
