A crystal of an N-long-chain acylglycine salt represented by the formula (I):
wherein R represents a linear or branched alkyl or alkenyl group having 7-21 carbon atoms; M represents an alkali metal or a basic amino acid, which produces diffraction peaks at positions of at least two diffraction angles (2θ±0.3°) selected from among 24.1°, 25.5°, 28.1° and 40.5° in powder X-ray diffraction analysis using Cu—Kα rays. The crystal of the N-long-chain acylglycine salt of the present invention is superior in the ease of handling, dissolution property and dispersibility in water.
一种由式(I)表示的 N-长链酰基甘氨酸盐晶体:
其中 R 代表具有 7-21 个碳原子的直链或支链烷基或烯基;M 代表碱金属或碱性氨基酸,在使用 Cu-Kα 射线进行粉末 X 射线衍射分析时,至少在 24.1°、25.5°、28.1° 和 40.5°之间的两个衍射角(2θ±0.3°)位置产生衍射峰。本发明的 N-长链酰基甘氨酸盐晶体在易操作性、溶解性能和水分散性方面都更胜一筹。
