Zeolite A

We are one of the supreme Zeolite A exporters and suppliers providing with high quality Zeolite A. Synthetic Detergent Grade Zeolite-A (Sodium Alumino Silicates), which is similar to natural minerals, was found to be a highly effective builder. Given the function, effectiveness and their safe ecological properties, synthetic Zeolite A has been accepted as an environmentally compatible builder.

Advantages of Zeolite-A
Average particle size 4 micron and maximum size not exceeding 20 micron of Zeolite-A has made it suitable to pass through the mesh size of clothes, preventing greying thereby.

    • Due to cubical shape with rounded corners and edges, Zeolite-A crystals do not remain on fabrics and are easily removed on rinsing.


    • The unwanted water soluble dirt molecules are absorbed on Zeolite particles.


    • It coagulates the colloidal dirt and pigments causing easy removal.


    • The presence of Zeolite-A does not interfere with the bio-degradation of Linear Alkyl Benzene Sulfonates (LABS).


    • Zeolite-A particles tend to form aggregate with other sewage constituents and are largely eliminated in the pre-sedimentation of sewage treatment.


  • Zeolite-A is formulated in detergents to the extent of 25-30%
