Abstract
A process for efficiently preparing fine zeolite particles comprising synthesizing zeolite in the presence of an alkaline earth metal-containing compound and/or with controlling the preparation process of zeolite, thereby giving fine zeolite particles being composed of crystalline aluminosilicate, the fine zeolite particles having a fine average primary particle size, being excellent in the cationic exchange properties and the oil-absorbing ability, having a fine average aggregate particle size, and being excellent in the dispersibility; fine zeolite particles obtainable by the above process; and a detergent composition comprising the fine zeolite particles, the detergent composition being excellent in the detergency.
