Abstract
This invention relates to detergent compositions having significantly improved calcium sequestration capacity as well as superior builder capacity in comparison to conventional aluminosilicate builder materials, while not redepositing on fabrics. More particularly, this invention relates to detergent compositions comprising microclusters of submicron crystallites of an aluminosilicate ion exchange material.
Claims21
