ABSTRACT:
Disclosed is a novel aqueous suspension of an antimicrobial compound having high stability of the suspension despite the use of such a very small amount of a suspending agent as not to cause any adverse influences on the inherent activity of the active ingredient. The suspending agent is a biocellulose as a microbial products of certain acetic bacteria which is not used in the prior art as a suspending agent in the prior art due to susceptibility to putrefaction while this defect of the biocellulose can be solved in the antimicrobial aqueous suspension by the use of an antimicrobial compound such as 2-methoxycarbonylamino benzimidazole, 2-pyridinethiol zinc-1-oxide and 2-(4-thiazolyl) benzimidazole.
