  • Patent number: 9770019
    Abstract: A kit for the production of an antimicrobial foam includes: a) a liquid composition which includes a1)one or more bispyridinium alkane and a2)one or more surfactants selected from non-ionic surfactants, amphoteric surfactants and cation-active surfactants, wherein the composition is formulated so that a foam can be produced therefrom, and b) a device for producing the foam from the composition. By using the bispyridinium alkanes the foam stability of liquid and surfactant-containing compositions is increased.
    Type: Grant

  • Patent number: 8609697
    Abstract: 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 ?-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.

  • Patent number: 8404261
    Abstract: A description is given according to the invention of a composition on an aqueous basis which comprises a) 0.001 to 10% by weight bispyridinium alkane, b) 0.1 to 30% by weight nonionic surfactant, c) 0 to 40% by weight aromatic alcohol and d) 0.01 to 10% by weight polyol selected from alkanediols and alkanetriols. The compositions, as mouthwash solutions, are more active than current commercial products and are distinguished by a pleasant taste and low tendency to foaming.

  • Patent number: 7387990
    Abstract: The invention relates to an alkaline disinfecting and cleaning composition which comprises one or more selected quaternary ammonium salts, one or more selected alcohol alkoxylates and one or more alkylamines. By exact choice of the components a composition is provided which can be formulated as concentrate and, as dilute aqueous ready-to-use solution, has good cleaning efficiency combined with good microbicidal activity.
