Definitions

  • the present patent application relates to hydrous liquid detergents or cleaners which contain peroxycarboxylic acid particles.
  • phthalimidoperoxoalkanoic acids such as 6-phthalimidoperoxohexanoic acid (PAP) are highly efficient bleaches, but are chemically very unstable in conventional liquid detergent formulations. In most cases, they completely decompose in a few days. Even if these liquid agents are freed from possible reactants of the peroxycarboxylic acid, such as unsaturated compounds, aldehydes, amines, chloride, etc., they still decompose in the presence of the surfactants, even if they are not oxidatively attacked.
  • PAP 6-phthalimidoperoxohexanoic acid
  • phthalimidoperoxoalkanoic acids are stable as only slightly water-soluble solids, they dissolve in the presence of surfactants, are highly reactive in this form and dissolve in solution both via a bimolecular reaction with the elimination of singlet oxygen and through Hydrolysis to the Phthalimidoalkanklare and H 2 O 2 decompose.
  • concentrations are practically not bleach active, so that in total the bleaching effect of the agent is lost during storage.
  • a problem with such formulations with, for example, sodium sulfate is the lack of phase stability and the lack of storage stability, especially under climatic changing conditions. Under alternating climate, the solubility of the sodium sulfate changes very strongly, which can lead to precipitation and the growth of partially very large sulfate crystals in the liquid agents. In addition, the flow behavior of these agents is unsatisfactory and the preparation is complicated in practice, since even during the manufacturing process due to the hydrate formation of the sodium sulfate initially large crystals can form, which do not dissolve again in the thickened formulation.
  • the present invention which aims to contribute to this, is an aqueous surfactant and bleach-containing liquid washing or cleaning agent which has a particulate peroxocarboxylic acid and is characterized in that it is methanesulfonic acid and / or an alkali metal, alkaline earth metal or ammonium salt of methanesulfonic acid.
