Therefore, the manufacturers of such aqueous preparations usually take measures for stabilizing the suspensions, dispersions or slurries. For example, it is known that aldehyde-releasing biocides reduce the growth and accumulation of such microorganisms in aqueous preparations and, thus, reduce the tendency of undesired alterations of these preparations, like unpleasant odours.
