Estimating the term…
Aqueous disinfectant concentrate which includes succinic dialdehyde, glutaraldehyde and/or formaldehyde, one or more alcohols of limited water miscibility and optionally usual auxiliaries. By diluting with water, a working solution can be prepared from the concentrate. The advantages of the new disinfectant concentrate or disinfectant are the reduced development of odor, an improved material compatibility, an improved microbicidal effectiveness and a clearly increased storage-stability. Furthermore, the activation usual up until now with disinfectants based on aldehyde is superfluous. Preferred application fields are surface and instrument disinfection.
Aqueous disinfectant concentrate consisting essentially of an aldehyde component selected from the group consisting of succinic dialdehyde, glutaraldehyde and mixtures of such aldehydes, and one or more alcohols of limited miscibility in water, said alcohols having a water miscibility of from 0.1 to 2 wt % and a vapor pressure at 20.degree. C. of less than 2 mbar, and being selected from the group consisting of a phenoxy alkanol with more than 2 carbon atoms in the alkyl chain optionally substituted in the phenyl moiety by C.sub.1 -C.sub.18 alkyl, a phenyl alkanol optionally substituted in the phenyl moiety by C.sub.1 -C.sub.18 alkyl, and an aliphatic glycol of the formula
