Storage- stable, anti-microbial compositions and products include a carrier and a ceragenin compound suspended in the carrier. Ceragenin compounds suspended in the carrier include a sterol backbone and a number of cationic groups attached to the sterol backbone via hydrolysable linkages. The carrier has a pH of 5.5 or less, which acts to stabilize the hydrolysable linkages and increase the shelf-life of the anti-microbial compositions and anti-microbial products. Nevertheless, the ceragenin compounds described herein are designed to break down relatively quickly (e.g., within about 5 days) if the pH environment of the ceragenin compounds is raised to about pH 6.5 or greater. |
