Inorganic ion exchange material and detergent composition.

摘要

A synthesized crystalline ion exchange material of the present invention has a chain structure and a composition represented by the following formula in anhydride form: xM2O.ySiO2.zM'O, wherein M represents Na and/or K; M' represents Ca and/or Mg; y/x is 0.5 to 2.0; and z/x is 0.005 to 1.0, the chain structure appearing as a main scattering peak in the Raman spectra at least at 970 +/- 20 cm<-><1> in the range of 900 to 1200 cm<-><1>. A detergent composition of the present invention contains the above synthesized crystalline ion exchange material and/or a hydrate thereof, and a surfactant.
