TeOX (Zeolite 4A)
Zeolite is the most promising substitute for sodium tripolyphosphate, a substance present in detergents considered to be one of the biggest environmental threats. Zeolites are a good alternative because they:


  • Enable the production of high performance detergents at a low cost;
  • Elevate the cations exchange capacity;
  • Are excellent structural agents for detergents;
  • Remove ions from heavy metals, iron, copper, and manganese, enabling tissue whitening and potentiating the bleaching process;
  • Are capable of liquid absorption, promoting anti-binding action in powder detergents;
  • Are safe for the environment and for humans;
  • Are Phosphor-free.


TeOX is a synthetic Zeolite of the 4A kind, produced from minerals that are abundant in nature like silicon, aluminium and sodium. TeOX’s high efficiency in absorption is related to its large internal surface, due to the fact that its crystal structure is characterized by cavities. The capacity for ionic exchange comes from a charge imbalance that attracts the Ca2+ cation closer, maintaining its neutrality.


TeOX Zeolite 4A is used mainly in the detergent industry. TeOX is different from natural zeolites, which cannot be used in detergents. This is because natural zeolites have a low capacity for ionic exchange, an elevated apparent density and particle sizes that leave a deposition of particles in clothes. 


Our TeOX Zeolites are also designed for the plastics and polymers industry, acting as an excellent co-stabilizer for PVC plastics and other applications. They are also designed for the production of asphaltic masses, improving the workability of asphalts with more consistent density and faster road compaction, in addition to reducing energy consumption.


In the dye industry, our Zeolites are used as an extender of TiO2 (Titanium Dioxide).
