New Benchmark in Green Chelation | Nouryon Dissolvine GL-47-S — Eco-Friendly High-Performance GLDA Chelating Agent

In numerous fields such as household cleaning, industrial cleaning, water treatment, and textile processing, chelating agents serve as critically functional additives in formulations—the "invisible guardians" that quietly enhance system stability. Metal ions such as calcium, magnesium, iron, and copper, which are commonly found in water, can readily cause scale deposition, reduced cleaning efficacy, fabric graying, and product oxidation or degradation. The core function of a chelating agent is to precisely sequester free metal ions at the source, preventing scaling, deactivation, and re-deposition, thereby effectively improving detergency and cleaning efficiency, stabilizing formulation systems, and extending both equipment service life and product shelf life.

For a long time, traditional chelating agents such as EDTA and phosphates have been widely used due to their basic chelation performance. However, they suffer from notable environmental drawbacks including poor biodegradability, prolonged environmental persistence, and a tendency to cause water eutrophication. These shortcomings no longer align with the global trend toward low-carbon, clean production, and these agents are being progressively phased out across industries. Against this backdrop of industry transformation, plant-based tetrasodium glutamate diacetate (GLDA) has emerged as a solution. Among them, Nouryon Dissolvine GL-47-S, with its natural-origin raw materials, superior performance, and exceptional safety profile, has become the new-generation green benchmark product replacing conventional chelating agents.

Compared with traditional chelating agents, complete biodegradability is the most defining differentiator of GLDA. Nouryon GL-47-S is derived from renewable plant-based L-glutamic acid—a food-grade source that is safe, pure, green, and sustainable. Its unique amino acid molecular structure enables rapid decomposition and assimilation by naturally occurring microorganisms, with an overall degradation cycle of just a few weeks—leaving no long-term residues or cumulative environmental pollution, and fully complying with stringent domestic and international environmental regulations. Additionally, the product is mild and low-irritation, posing no harm to human skin or eyes. It has been certified under the EU REACH regulation and the U.S. EPA Safer Choice program, making it safe for use in highly sensitive applications such as food-contact cleaning and children's personal care products, and ideally suited for premium, safety-focused formulations.

In terms of practical application performance, GLDA delivers all-round chelation capabilities across a wide temperature range, a broad pH spectrum, and with exceptional stability. The product operates effectively within an extreme pH range of 2 to 12, making it compatible with the vast majority of complex formulations in both household and industrial applications. It efficiently chelates calcium and magnesium ions in hard water—softening water, preventing scale formation, and significantly enhancing the detergency and wetting performance of surfactants. At the same time, it effectively sequesters heavy metal ions such as iron and copper, inhibiting metal-catalyzed oxidation reactions, significantly slowing product discoloration, off-odors, and degradation, and effectively extending formulation shelf life. Even at low temperatures below 10°C, it maintains high chelation activity, making it ideally suited for today's mainstream low-temperature energy-saving washing and low-temperature industrial cleaning processes.

Additionally, Nouryon GL-47-S offers excellent formulation compatibility, enabling efficient co-formulation with bactericides, enzymes, and various surfactant systems. When used in combination with bactericides, it can reduce the required bactericide dosage by 20% to 80% while delivering more stable antimicrobial efficacy and effectively preventing issues such as microbial contamination, off-odors, and discoloration in the system. It also demonstrates excellent compatibility with detergent enzymes, effectively protecting enzyme activity from being compromised by metal ions, and significantly enhancing overall soil removal, stain elimination, and surface renewal performance. Leveraging its high purity, heat resistance, and non-gelling characteristics—all exceeding industry standards—it is well-suited for demanding processes such as super-concentrated additive formulations, high-temperature sterilization, and high-temperature drying, with performance stability surpassing that of conventional GLDA products.

The product provides comprehensive coverage across both household and industrial cleaning applications, and is widely suitable for laundry detergents, automatic dishwashing detergents, personal care products, car cleaning, metal processing, recirculating water treatment, textile printing and dyeing, and many other fields. Against the backdrop of the global wave of green formulation upgrades, Nouryon Dissolvine GL-47-S offers the dual core advantages of high-performance chelation and complete biodegradability with non-toxic safety. It helps businesses develop clean-label, green-compliant products, making it the preferred chelating agent for replacing EDTA and phosphates to achieve both environmental formulation upgrades and enhanced performance.
