摘要:
The present invention relates to a granular adsorbent having a high uptake capacity for liquid ingredients of detergents and cleaning preparations, comprising(a) 60 to 80 wt. % of a cation-exchanging, synthetic aluminosilicate selected from the group consisting of zeolite A, zeolite X and mixtures thereof, said aluminosilicate containing water of hydration;(b) 0.05 to 5 wt. % of sodium silicate having a Na.sub.2 O to SiO.sub.2 mol ratio within the range of about 1:2 to about 1:3.5;(c) 3 to 15 wt. % of a homopolymer of a monomer selected from the group consisting of acrylic acid, methacrylic acid and maleic acid; or a copolymer made by polymerizing a mixture containing at least one of said monomers, and(d) 8 to 18 wt. % of water removable at a temperature of about 145.degree. C.The adsorbent may optionally include up to 5 wt. % of a nonionic surfactant. The adsorbent has an average particle size within the range of about 0.2 to 1.2 mm, and a bulk density in the range of about 400 to 700 g/l.
