Green nature
Dissolvine® GL is based on the food-approved natural amino acid salt, monosodium L-glutamate (MSG). This results in a good biological breakdown as is confirmed by the Closed Bottle biodegradability test (OECD 301D).

With respect to the green nature of GLDA; the molecule is largely based on natural, replaceable and sustainable raw materials (see figure 1). According to the Bra Miljöval protocol of the Swedish society for Nature conservation it is for 86% based on renewable resources, a much higher proportion in comparison with other chelating agents.

The excellent eco-toxicological properties are of benefet when used formulations, containing complexing agents, are discarded into the environment.  The Dissolvine® GL manufacturing process is very efficient with only ammonia as by-product, which is collected and re-used as raw material for other products and industrial processes. This makes that the ecological footprint of Dissolvine® GL is significantly smaller than traditional alternatives. See figure 2.
