发明名称 Powder composition of hydroxypropyl betacyclodextrin and process for preparing the same
摘要 <p>Powdered hydroxypropyl- beta -cyclodextrin compsn. contains less than 25% of 100 mu m particles and dissolves in less than 5 mins. at 21 degrees C for a soln. contg. 20% dry matter (as measured in a test I). The compsn. pref. dissolves in less than 3 (pref. less than 2) mins. Particles smaller than 40 mu form less than 10% of the powder, particles bigger than 315 mu form less than 40% of the powder. The flow number is 60-90, pref. 70-85. Compressibility is greater than 30 N, pref. greater than 100 N (evaluated in a test II).</p>
