An aqueous-based composition which includes a) at least one bispyridinium alkane (for example octenidine) and b) at least one stabilizer selected from antioxidants, complexing agents, reducing agents, UV filters and photoprotective agents, in particular &#x3b1;-tocopherol, and BHT. The composition can also include c) one or more auxiliaries selected from, for example, nonionic surfactants, ethers, solvents and polymers, in particular fatty alcohol alkoxylates and alkoxylated fatty acid monoglycerides. The presence of the stabilizer reduces or prevents the appearance of decomposition products of bispyridinium alkanes and, in the case of the presence of auxiliaries, of decomposition products of the auxiliaries, such as ethers and peroxides.

Stabilized, antimicrobially effective composition with a content of bispyridinium alkane

An antimicrobially effective composition includes a) at least 0.15% by weight of bispyridinium alkane, b) at least 3.5% by weight of humectant and c) water. Upon dilution with water, the composition produces a solution with an osmolality of from 230 to 350 mOsmol/kg and is free from surfactant. It is used as an antiseptic and is suitable for use in a method for the disinfection of injured or uninjured skin of a human being or animal, preference being given to use in the case of newborns, in particular those born prematurely.
