    Abstract: PROBLEM TO BE SOLVED: To provide a powder shape finely crushed binder useful on the production of tablets, and to provide a method for producing the same. SOLUTION: This powder shape finely crushed binder comprises a vinyl lactam polymer, having an average particle size of ≤35 μm and an apparent density of ≤0.2 g/ml. The method for producing the binder comprises spraying a vinyl lactam polymer aqueous solution having a solid content of 1 to 35 wt.% with a single liquid nozzle under a pressure of ≥8 MPa or with a double liquid nozzle under a pressure of ≥0.2 MPa, and then drying the sprayed product with a hot gas flow.

    Abstract: PROBLEM TO BE SOLVED: To obtain a crystalline solid of the subject compound substantially not containing an additive and having virtually sufficiently low hygroscopic property. SOLUTION: This crystalline solid constituted of a glycine-N,N-diacetic acid derivative represented by formula I [R is a 1-30C alkyl or a 2-30C alkenyl, a group of formula II (A is a 1-12C alkylene bridge, etc.; M is H or an alkali metal, etc.), etc.] is produced by distilling away water content of an aqueous solution of (A) glycine-N,N-diacetic acid derivative I [R is a 1-20C alkyl or a group of formula II, etc.] as a starting substance. Crystallization is carried out by adding a crystalline component A in an amount of 0.001-50wt.%, preferably 0.01-10wt.% based on an amount of the component A in a starting substance as a nucleus for crystallization and the crystallization temperature is controlled to 10-100 deg.C, especially 40-80 deg.C. The resultant crystalline solid has a purity of 70-99.9%, especially 80-99.5% based on total amount of solid.
