- 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.

Technical Details & Test Data
- Density Data
Liquid density The density of the liquid can be used as a quick reference to check the concentration of the material. See Figure 1.
Figure 1: Density of Dissolvine® GL plotted against GLDA-Na4 concentration based on GL-38, GL-47-S and GL Premium.
- Viscosity Data
Viscosity is an important parameter for handling products and is dependent on concentration and temperature. Figure 2 shows the viscosity of various concentrations of GLDA-Na4 solutions as a function of temperature.
