Dissolvine GL  is a biobased sequestrant and chelating agent..
Dissolvine GL  can be used to replace NTA, EDTA, phosphates and phosphonates in several cleaning products and formulations.
Dissolvine GL  is based on natural amino acid salt, monosodium L-glutamate (MSG) and is readily biodegradable.

Applications of Dissolvine GL :
- Domestic and Industrial Dishwashing
- Detergents
- Descaling
- Personal Care
- Industrial Cleaning
- Pulp Bleaching

Dissolvine GL  is glutamic acid diacetic acid, tetra sodium salt (GLDA-Na4). 
Dissolvine GL  has four carboxylic acid groups and combined with a centralized nitrogen atom these carboxylate groups provide strong multiple bonds with diand 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 Dissolvine GL molecule allows it to be readily recognized as food by bacteria and thus for Dissolvine GL 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.
Dissolvine GL is used extensively to control metal ions in water-based systems for countless applications. 
They are highly effective in the control of water hardness ions and find wide application in cleaning surfaces, descaling boilers, processing textile and preventing scale in heating systems. 
In another area, the control of metal reactivity, they are important processing tools for reducing the detrimental effect of metals in pulp bleaching for paper manufacturing, improving personal care formulations, stabilizing food products and for pharmaceutical formulations. 
Finally, they are also used extensively in metalworking areas, ranging from metal plating, dosing essential elements to plants and supplying iron for the development of photographic films and paper using silver halide technology. 

Dissolvine GL has been developed as part of this continuing quest to find new and improved products. 
Produced from natural and sustainable raw materials, Dissolvine GL is readily biodegradable, with a high solubility over a wide pH range.

Dissolvine GL is a new type of green degradable chelating agent, can replace traditional phosphonates, EDTA, NTA. 
Dissolvine GL is suit for a wide pH range, with high solubility, high temperature resistance, strong detergency, no ecological toxicity, has synergistic effect with fungicides, and no irritation to skin and eyes.
