WeylClean® MnOX

The green alternative for auto dish wash.
Natural, biology inspired tea stain removal in automatic dishwashing applications.


WeylClean® MnOX is a highly efficient bleach catalyst. In combination with persalts (e. g. sodium percarbonate) it boosts tea stain removal in automatic dishwashing applications. Being a true catalyst, it is used in low concentrations and saves valuable formulation space.

  • White-rot fungi use the related chemistry in natural wood degrading processes
  • Chemically identical with the mineral Lindbergite (found in the Black Forest)
  • Readily biodegradable according to OECD 301 test methods
  • Its low solubility in water enhances its storage stability in alkaline detergents
Performance Data
  • Significantly better tea stain removal in the temperature range of 40 to 60 °C
  • No catalase properties, i. e. no H2O2 is destroyed in side reactions
Technical Profile
  • Free-flowing white crystals
  • Chemical name: Manganese oxalate dihydrate
  • Active content: >99 %
  • Typical use level: 0,1 – 0,5 %
  • Optimum pH for best performance: 10,3 to 10,5
  • Compatible with most ADD ingredients
  • Best storage stability in neutral or slightly alkaline detergent environment. WeylClean® MnOX is anaerobically bio-degradable and meets the EU Ecolabel requirements
  • Important remark: WeylClean® MnOX is designed for use in ADD Applications. It should not be applied in laundry processes as fabric damage cannot be ruled out
