摘要: Amorphous sodium silicate powder exhibiting excellent water softening power and suitable as a detergent builder is provided. This amorphous characterized in that when the molar ratio of SiO 2 /Na O expressed by n specific surface area thereof S(m /g), following expressions: 1.20≦n≦1.60 0.10≦S≦0.90 0.008×n 8 .6 ≦S≦0.063×n .1 are satisfied.
