Product Applications
  • Boosting agent for disinfecting products (with low skin irritation). Improved detergency at high water hardness.
  • Hard surface cleaning performance is improved in combination with gluco(hepto)nates. Scale removal at high pH. Scale inhibitor in laundering and dishwashing applications.
  • Booster for stain removal in dish washing detergents better than citrates and phosphates.
  • Scum inhibitor in bathroom cleaners. Improved cleaning & foaming in shampoo applications.
  • Storage stabilization of bleaching agents (perborates/percarbonates) and unsaturated alkyl chain-based surfactants.
  • Transport cleaners: Oil and iron removal at slightly acidic, neutral or mild alkaline conditions. Replacement for NTA.
