Area: | Chemical Sciences, Material Sciences |
Focus Area: | Zeolite Manufacturing |
Patent: | IN182635, IN182636, US7560093 |
Social Benefits: | Detergent grade Zeolite-A is a crystalline aluminosilicate with a three dimensional micro porous structure built up from SiO4 and AlO4 tetrahedrons in which the negative charges are compensated by extra framework mono or multivalent cations. These cations can easily be exchanged from a solution to Zeolite or vice versa without affecting the lattice structure. This cation exchange property of Zeolites is responsible for its action as a water softener wherein calcium cations present in water are exchanged with sodium ions of the zeolite. This explains its commercially very important application as a water softener in house hold detergents, substituting sodium tripolyphosphate. In recent years, there has been an upsurge of interest in use of Zeolite-A as a builder in the detergent powder. The most important reason is the increased awareness and concern about the polluting effect on the environment caused by the phosphates, the conventionally used builder in the detergent formulation. |
