Synthetic Molecular Sieve 4A Zeolite

Synthetic Molecular Sieve 4A Zeolite is a fine sodium aluminosilicate powder used as a detergent builder and water-softening material, providing effective calcium-ion exchange and controlled particle characteristics for powder detergent formulations.

Chemical Name
Sodium Aluminosilicate
Molecular Formula
Na2O·Al2O3·2SiO2·4.5H2O
EINECS
215-684-8
PRODUCT OVERVIEW

Product Description

Synthetic Molecular Sieve 4A Zeolite is a fine, free-flowing sodium aluminosilicate powder developed for detergent and related industrial formulations. The material provides effective calcium-ion exchange capability, helping reduce the influence of water hardness in compatible detergent systems. Its high whiteness and controlled fine-particle distribution also support consistent dispersion throughout powder formulations. The referenced synthetic 4A grade is manufactured rather than obtained as natural zeolite and is controlled according to calcium-exchange capacity, whiteness, pH, ignition loss, aluminum content, bulk density, and particle-size specifications. It can be considered as a detergent-builder component in formulations where water softening and reduced dependence on phosphate-based builders are required. Final formulation compatibility and product specifications should be confirmed against the current supplier technical documentation.
