Maximize the performance of your biocide and preservatives
Dissolvine GL-47-S is an important ingredient in formulations providing benefits that enhance the effectiveness of biocides and biological preservatives. Dissolvine GL-47-S is effective on molds and both Gram Positive and Gram Negative bacteria. When you include Dissolvine GL-47-S in the formulations, you can significantly reduce the amount of active needed while preserving efficacy and save on formulation costs.
Species is deprived of multivalent cations weakening the outer surface and more vunerable for the action of preservatives.

- Chemical and Physical Properties
Dissolvine® GL product range including various chemical and physical properties. Dissolvine® GL-38 (offered in EMEA) and Dissolvine® GL-47-S (offered worldwide) are standard multi-purpose liquid chelating agents. The primary difference in these products is the active ingredient content (38 % vrs 47%) and also that the ‘S’ version is high purity (NTA free). Dissolvine® GL-PD-S is a spray dried equivalent of the liquid product, Dissolvine® GL-47-S, is convenient for the preparation of highly concentrated formulations (solid or liquid). This solid product readily dissolves in water to yield a clear, slightly yellow liquid, is hygroscopic and should be stored in closed bags or containers until it is used.
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 or high purity GL-47-S.
Viscocity
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.

Storage & Handling
- Storage Conditions
- Store in original packing or in PVC, PP, PE, stainless steel or bituminized tanks.
- Avoid contact with aluminum, zinc, nickel, copper and copper alloys. It is advised to re-test the material after three years of storage.
