Dissolvine GL is an outcome of our continuing effort to develop new and improved products.
Dissolvine GL is produced from monosodium L-glutamic acid (MSG) which is a biobased naturally occurring amino acid, GLDA is readily biodegradable and offers a high solubility over a wide pH range.
Dissolvine GL does not sensitize human skin, provides enhanced biocidal boosting power and improved biodegradability properties.
CAS Number: 51981-21-6
Molecular Weight: 351.1
Compared to phosphates, GLDA is a far more effective chelating agent and does not contribute to eutrophication.
Dissolvine GL is glutamic acid diacetic acid, tetra sodium salt (GLDA-Na4).
GLDA has four carboxylic acid groups and combined with a centralized nitrogen atom these carboxylate groups provide strong multiple bonds with di- and trivalent metals ions.
Dissolvine GL is based on the food-approved natural amino acid salt, monosodium L-glutamate (MSG).
Manufacture with this biobased raw material allows for more than half of the carbons in GLDA to be biobased.
We believe that this natural amino acid structure in the GLDA molecule allows it to be readily recognized as food by bacteria and thus for GLDA to be readily biodegradable.
Dissolvine GL has excellent low toxicity and low ecotox profiles and does not require dangerous labeling.
Significantly, Dissolvine GL meets the requirement as a safer chemical by the U.S. EPA’s Design for the Environment program as well as being recognized as safe by numerous international institutions.
Dissolvine GL is a strong chelate for hard water metal ions – like Ca2+ – and cleaning formulations containing it benefit from enhanced water softening, cleaning and stability.
Chemical Name: Glutamic acid, N,N-diacetic acid, tetra sodium salt
Chemical formula: GLDA-Na4
Dissolvine GL is a glutamic acid, diacetic acid and tetra-sodium salt (GLDA-NA4), it's a pure product that contains no other weaker chelates as a substitute such as citrates or gluconate.
With 100% of the active content being GLDA, Dissolvine GL offers maximum chelation power and efficiency.
Dissolvine GL is a sustainable, innovative material.
Dissolvine GL is extensively used to control metal ions in water based systems for multiple applications.
Dissolvine GL is highly effective in the control of water hardness ions and can also be used in cleaning surfaces, descaling boilers, processing textiles and preventing scale formation.
In cleaning formulations and under harsh washing conditions, Dissolvine GL complexes hard water ions very well and retains its high chelating values at elevated temperatures more than other chelating agents.
Dissolvine GL is an important tool in controlling metal ion reactivity as it reduces the detrimental effect of metal catalysts in peroxide cleaners.
Dissolvine GL can also be used to enhance the physical properties of metal ions, supplying iron for gas scrubbing and providing essential elements to growing plants.
Dissolvine GL is produced from the monosodium L-glutamic acid (MSG), a bio based naturally occurring amino acid, ensuring Dissolvine GL is readily bio-degradable.
This alongside the source material of plant based/sugar waste, Dissolvine GL is an environmentally friendly alternative.
Dissolvine GL is a bio-based chelating agent derived from monosodium L-glutamic acid (MSG) which is a bio-based naturally occurring amino acid.
Dissolvine GL can be used to replace NTA, EDTA, phosphates and phosphonates in several cleaning products and formulations.
