How Green Chelator GLDA Solves Stubborn Stains and Grease

Confronted with greasy utensils, stubborn tea stains, and hardened limescale in kitchens, an innovative green cleaning ingredient is quietly transforming our approach to cleanliness.

Kitchen maintenance presents daily challenges for both households and food service businesses. While conventional cleaning products can remove grease, they often contain irritating components or non-biodegradable substances that pose potential risks to human health and ecosystems.

In recent years, Tetrasodium Glutamate Diacetate (GLDA), a novel green chelating agent, has gained prominence for its exceptional cleaning performance and environmental credentials, reshaping the formulation and experience of kitchen cleaning products.

01 Understanding Tetrasodium Glutamate Diacetate (GLDA)

Tetrasodium Glutamate Diacetate (GLDA) is an innovative green chelator with the chemical formula C9H9NO8Na4 and CAS number 51981-21-6.

This compound typically appears as a transparent or light yellow odorless liquid, though it is also available in solid granule or powder forms.

GLDA's core advantage lies in its unique bio-based origin. Derived from renewable plant-based L-glutamic acid, it offers reliable performance while aligning with modern environmental standards.

What particularly distinguishes GLDA from traditional chelators is its exceptional biodegradability. After use, microorganisms readily recognize and metabolize it as a food source, preventing persistent environmental accumulation.

02 Four Exceptional Properties Underpinning Kitchen Cleaning Efficacy

Superior Biodegradability

GLDA represents a safe, readily biodegradable chelating agent that bacteria rapidly break down after use, avoiding long-term environmental burden. This characteristic creates a stark contrast with traditional, poorly biodegradable alternatives like EDTA.

Powerful Chelating Capacity

GLDA demonstrates stronger chelating capability for calcium and magnesium ions, delivering superior cleaning performance compared to phosphates and citrates.

Its calcium chelation capacity approaches that of traditional powerful chelators like EDTA, outperforming many other biodegradable alternatives.

Broad pH Adaptability

GLDA maintains excellent solubility from strongly acidic to highly alkaline systems, enabling adaptation to diverse kitchen cleaning scenarios.

Whether addressing acidic food stains or alkaline grease, GLDA sustains high solubility and cleaning effectiveness.

Thermal Stability

Thermogravimetric analysis confirms that GLDA remains stable at 170°C for 6 hours or at 150°C for one week without decomposition.

This thermal resilience makes GLDA particularly suitable for high-temperature kitchen environments and hot-water cleaning applications, ensuring consistent performance without thermal degradation.

03 Diverse Applications: GLDA's Versatility in Kitchen Cleaning

Tableware Cleaning

GLDA finds widespread application in dishwashing liquids and plate cleaning formulations. Its effectiveness has been validated in automatic dishwasher detergents.

Patent formulations reveal that dishwashing degreasers containing 3%-5% GLDA efficiently remove grease from tableware, demonstrating excellent performance even under low-temperature conditions.

Kitchen Surface Cleaning

GLDA can be incorporated into household cleaning products like kitchen degreasers, effectively addressing various surface contamination challenges. Its strong chelating ability breaks down hard water stains and mineral deposits, maintaining pristine conditions on countertops and utensils.

Food Industry Sanitation

In industrial cleaning contexts, GLDA proves valuable for food processing equipment maintenance, effectively preventing scale formation and extending equipment lifespan.

Synergistic Disinfection Enhancement

GLDA exhibits clear synergy with disinfectants. For numerous antimicrobial agents, GLDA's preservative and disinfectant enhancement effects can reduce usage requirements by 20%-80%.

This property gives GLDA significant value in kitchen disinfection products, improving sterilization efficacy while reducing chemical consumption.

04 Environmental Advantages: GLDA Versus Traditional Chelators

With growing health and environmental awareness, coupled with increasingly stringent regulations, the cleaning industry urgently requires sustainable alternatives to conventional chelators.

Compared with traditional options, GLDA demonstrates compelling comprehensive advantages:

• Versus EDTA: GLDA offers superior biodegradability while providing stronger chelation capacity for calcium and magnesium ions

• Versus Citrates: GLDA delivers enhanced chelating power, particularly suited for high-temperature and high-alkaline cleaning tasks

• Versus STPP (Sodium Tripolyphosphate): GLDA is phosphate-free and environmentally friendly, eliminating risks of aquatic eutrophication

In the ongoing evolution toward greener chelators, GLDA combines ready biodegradability, powerful metal chelation, and practical handling convenience, positioning it as an ideal replacement for traditional agents.

05 Yuanlian Chemical: Advancing GLDA Green Solutions

As an advocate for sustainable chemistry, Yuanlian Chemical continuously monitors GLDA's applications and development within the cleaning sector.

Technical specialists at Yuanlian Chemical note that compared to household laundry detergents, chelator formulation for automatic dishwasher (ADW) detergents presents greater technical challenges, including more resistant greases, high operating temperatures, and alkaline conditions.

Whereas conventional formulations typically incorporated citrates or phosphate-based chelators like STPP, these alternatives present specific limitations and weaknesses.

Yuanlian Chemical emphasizes that GLDA's superior chelation capacity and green credentials make it particularly suitable for automatic dishwasher detergent applications.

Internationally recognized brands have already incorporated GLDA into liquid formulations for automatic dishwasher detergents.

Yuanlian Chemical highlights that in phosphate-free detergent formulations, GLDA can completely replace STPP and similar phosphates. Advancements in this application area further validate GLDA's powerful cleaning efficacy and environmental profile.

As a champion of green chelating agents, Yuanlian Chemical continues to promote GLDA adoption across multiple cleaning sectors, delivering innovative solutions for the green cleaning industry.

06 Practical Application Success Stories

GLDA has demonstrated significant practical achievements in kitchen cleaning:

• Automatic Dishwasher Detergents: Leading international brands have incorporated GLDA into liquid automatic dishwasher detergent formulations, effectively addressing challenging grease under high-temperature alkaline conditions

• High-Efficiency Tableware Degreasers: Patented formulations containing 3%-5% GLDA conveniently remove tableware grease even at low temperatures, with diluted pH below 10, minimizing impact on human health and aquatic ecosystems

• Multi-Surface Kitchen Cleaning: GLDA enables formulation of diverse kitchen cleaning products, including dish liquids and kitchen degreasers, effectively addressing various kitchen stains

These practical applications demonstrate GLDA's efficiency and practicality in kitchen cleaning while highlighting its environmental benefits.

07 Future Perspectives

With continuously evolving environmental awareness and increasingly stringent regulations, green cleaning agents represent the future mainstream direction.

As a high-performing and environmentally responsible green chelator, GLDA holds promising application prospects throughout kitchen cleaning sectors.

Ongoing research and innovation by companies like Yuanlian Chemical will further expand GLDA's application scope in kitchen cleaning, providing consumers with safer, more efficient, and sustainable cleaning solutions.
