CERAGENIN PARTICULATE MATERIALS AND METHODS FOR THEIR PREPARATION

摘要

Particulate ceragenin materials may be manufactured by (i) providing a ceragenin feed material comprised of ceragenin molecules, each having a sterol backbone and a plurality cationic groups attached thereto; (ii) fracturing the ceragenin feed material in a milling apparatus to produce a ceragenin particulate material having a particle size distribution with a median particle size in a range from 5 nm to 20 mum; and (iii) during fracturing, maintaining the ceragenin feed with a moisture content of less than or equal to 10% by weight.
