ABSTRACT:
A detergent builder consisting essentially of an inorganic fine powder composed mainly of an alkali metal aluminosilicate having an X-ray diffraction pattern substantially the same as that of zeolite of the type A and having a degree of crystallization in the range of from 35 to 75%, wherein the inorganic fine powder has a primary particle size smaller than 1.mu. and a secondary particle size smaller than 4.mu., the inorganic fine powder has a buffer capacity (S) of at least 132 ml/100 g of solids, the buffer capacity being expressed by an amount of hydrochloric acid necessary for lowering the pH of a 1% aqueous dispersion of said inorganic fine powder from 9.0 to 6.75 when the dispersion is titrated with 0.4 N hydrochloric acid at a rate of 20 to 50 ml/hr, and wherein the inorganic fine powder has a calcium ion binding property (C. I.) of at least 70 mg/g as expressed as CaO.
