摘要:
The invention provides an aqueous-based composition which comprises 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 α-tocopherol, and BHT. The composition can also comprise 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.

摘要:
The invention relates to a preservative with algicidal and fungicidal action in the form of a dispersion which includes
a) at least one algicidal triazine, b) at least one fungicidal isothiazolone and c) at least one dispersion stabilizer chosen from the group consisting of
c1) sulphite salt, hydrogen sulphite salt, compound which releases sulphite and compound which releases hydrogen sulphite, and c2) hypophosphite salt and compound which releases hypophosphite salt;
and to the use of the preservative in an aqueous dispersion for use in or on technical products for internal or external application.
