AQUEOUS ANTI-MICROBIAL COMPOSITIONS INCORPORATING A BIGUANIDE, HAVING PH NOT LESS THAN 0.1 BUT LESS THAN 5

摘要

A aqueous medium containing a biguanide, particularly a biguanide oligomer, and having a pH of less than 5. The biguanide oligomer may be a poly(hexamethylene biguanide) having up to 15 repeat units. The medium has improved storage stability compared to commercially available systems and is at least as effective as a biocide.
