Kemsurf DSA

Product Category: Anionics

Sodium Lauryl Sulphate (Sodium Lauryl Sulfate)

INCI Name: Sodium Lauryl Sulfate

Quick Links

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.

​

Key Features

 

  • Excellent detergency and foaming performance - Provides strong cleaning efficiency with rich, stable foam, making it highly effective for removing oils, greases, and particulate soils.

  • Effective wetting and dispersing capability - Delivers good surface activity, improving substrate wetting and aiding the dispersion of soils and formulation components.

  • Versatile and compatible surfactant - Compatible with anionic and non‑ionic systems, offering good formulation flexibility and reliable performance across a wide range of industrial and personal‑care applications.

​

Applications

 

Kemsurf DSA is used in a wide range of industrial, household, and personal‑care applications, including:

​

Household Detergents
– Provides strong cleaning, emulsification, and foaming performance in liquid and powder detergent formulations, supporting effective removal of oils, greases, and particulate soils.

​

Personal Care Formulations
- Used as a primary surfactant in shampoos, shower gels, and liquid hand soaps, delivering rich foam and effective cleansing performance.

​

Industrial & Institutional Cleaning
– Suitable for hard surface cleaners and general industrial cleaning products where good wetting, detergency, and foam stability are required.

​

Laundry Applications
– Used in fabric cleaning formulations, providing efficient soil removal and compatibility with a range of detergent systems.

​

Dispersing Agent
– Functions as a dispersant to help evenly distribute particulates and improve formulation stability, particularly in systems containing pigments or solids.

​

Hard Surface Cleaners
– Enhances wetting and soil removal for cleaning a wide variety of domestic and industrial surfaces.
