  • the invention relates to new aqueous bleaching and disinfecting agents containing alkali metal hypochlorites, alkyl ether sulfates, amine oxides, fatty acid salts and alkali metal hydroxides in selected proportions.
  • EP-A 0 274 885 (1CI) recommends the use of mixtures of linear and branched amine oxides. According to the teaching of EP-A 0 145 084 (Unilever), mixtures of amine oxides with soaps, sarcosinates, taurides or sugar esters can also be used for this purpose.

  • German Patent DE-C1 43 33 100 the applicant has already proposed stable and sufficiently viscous aqueous bleaching and cleaning agents based on hypochlorites, fatty alcohol ether sulfates and amine oxides, which contain amine oxide phosphonic acids as a mandatory component. Even if the preparations are not objectionable from an application point of view, the use of phosphonic acids is not without problems with regard to the introduction of phosphorus compounds into surface waters. Since the amine oxide phosphonic acids are also comparatively expensive ingredients, there continues to be a need in the market for simple, viscous formulations which are characterized by high storage stability, chlorine resistance and good dispersing properties with a low hypochlorite content.
  • the object of the invention was therefore to provide new aqueous bleaching and disinfecting agents which are free from the disadvantages described.
  • the invention relates to aqueous bleaching and disinfecting agents free from amine oxide phosphonic acids, containing - based on the agents -

  • the alkyl ether sulfates can have a conventional or restricted homolog distribution.
  • the alkyl ether sulfates are preferably used in amounts of 2 to 4% by weight, based on the composition.
  • Amine oxides are also known substances, which are occasionally attributed to the cationic, but usually the nonionic surfactants.
  • the nonionic surfactants For their preparation, one starts from tertiary fatty amines, which usually have either one long and two short or two long and one short alkyl radical, and is oxidized in the presence of hydrogen peroxide.
  • the amine oxides which are suitable for the purposes of the invention follow the formula (II) R 3
  • R 2 represents a linear or branched alkyl radical having 12 to 18 carbon atoms and R 3 and R 4 independently of one another R 2 or an optionally hydroxyl-substituted alkyl radical having 1 to 4 carbon atoms.

Salts of technical coconut or tallow fatty acids are preferably used.
  • the fatty acids which are neutralized in situ when they are introduced into the mixture can also be used instead of the salts.
  • the fatty acid salts are preferably used in amounts of 1.5 to 2% by weight.
  • Suitable alkali metal hydroxides are potassium hydroxide and, in particular, sodium hydroxide, which are preferably used in amounts of 1.5 to 2% by weight and serve to adjust the pH of the compositions to an optimal value of 12.5 to 14.
  • the agents according to the invention have a viscosity above 100 mPas - measured at 20 ° C. in a Brookfield viscometer - are stable in storage, resistant to chlorine consumption and are distinguished by excellent dispersibility for dye pigments.
