General Description

Chemical Formula: H2Al2(SiO3)4-nH2O

Bleaching Earth is a naturally occurring or acid activated clay material used primarily for the purification and decolorization of edible oils, mineral oils, and industrial liquids. It is processed to enhance its adsorption capacity, surface area, and affinity for pigments, impurities, trace metals, soaps, and oxidation products.

 

Bleaching Earth plays a critical role in refining processes where color reduction, stability improvement, and impurity removal are essential. Its consistent adsorption performance and compatibility with continuous and batch processing systems make it a standard processing aid in oil refining, petrochemicals, and specialty chemical industries.
