What Exactly is Tetrasodium Glutamate Diacetate?
GLDA is a biodegradable, plant-based chelating agent—commonly abbreviated as GLDA or Tetrasodium Glutamate Diacetate (GLDA 4Na). Developed as an alternative to traditional, non-biodegradable agents like EDTA and NTA, GLDA is derived from L-glutamic acid, a naturally occurring amino acid found in many plant and animal proteins.
What is Its Role?
GLDA’s primary function is to bind and control metal ions such as calcium, magnesium, and iron in water-based systems, which helps improve product stability, performance, and appearance. It is commonly found in:
- Personal care products (shampoos, lotions, cleansers)
- Hard surface cleaners and detergents
- Dishwashing and laundry products
- Agricultural formulations
- Water treatment chemicals
Because GLDA is non-toxic, non-sensitizing, and readily biodegradable, it has rapidly gained popularity as a “greener” and safer alternative to traditional chelating agents.

Even after knowing that GLDA is derived from natural plant and animal proteins, you might still be wondering: Is it safe?
Is GLDA Safe for Humans?
Yes—because it’s supported by scientific assessment.
In 2021, the Cosmetic Ingredient Review (CIR) Expert Panel evaluated GLDA and concluded it is safe to use in cosmetics at industry-standard concentrations.
📘 Scientific Testing Includes:
- Oral toxicity
- Skin and eye irritation
- Reproductive and developmental toxicity
- Inhalation safety
- Genotoxicity and mutagenicity
Key Findings:
- ✅ Low acute toxicity (LD50 > 2,000 mg/kg)
- ✅ Non-irritating to skin and eyes
- ✅ Non-sensitizing (no allergic skin reactions)
- ✅ Not mutagenic or genotoxic
- ✅ Safe for long-term exposure
These results reflect strong scientific consensus supporting GLDA 4Na as a low-risk ingredient for both rinse-off and leave-on products.
Environmental Impact
Biodegradability & Eco-Safety
GLDA is designed for green chemistry. Unlike EDTA, which resists breakdown in the environment, tetrasodium glutamate diacetate (GLDA-4Na) is readily biodegradable and breaks down quickly under microbial action.
⏳ Biodegradation Timeline: A few days to several weeks depending on pH and temperature.
🐟 Low Ecotoxicity:
- Safe for aquatic organisms
- No bioaccumulation in the food chain
These properties make GLDA a preferred option for eco-conscious formulations in home care, personal care, and agrochemical products.
Potential Impurities & Quality Control
One impurity occasionally found in GLDA during production is nitrilotriacetic acid (NTA)—classified by IARC as a Group 2B compound (possibly carcinogenic).
However:
- NTA levels in high-quality GLDA are extremely low
- Rinse-off products pose minimal risk
- Studies show no genotoxicity at trace levels
🎯 Reputable tetrasodium glutamate diacetate suppliers implement strict purification processes to keep impurities below regulatory thresholds, ensuring safe, consistent performance.
Regulatory Approvals
GLDA is widely accepted and regulated globally:
- EU: Listed in CosIng and approved under Regulation (EC) No. 1223/2009
- USA: Approved by the FDA for select uses
- Canada: Registered in the Domestic Substances List (DSL)
- Japan & Korea: Fully approved under local chemical frameworks
Whether you’re searching for tetrasodium glutamate diacetate MSDS, tetrasodium glutamate diacetate CAS number (51981-21-6), or just want to buy GLDA, rest assured that this ingredient meets strict safety and environmental standards worldwide.
Why Choose GLDA?
GLDA isn’t just safe and effective—it’s also:
- 🌱 Biodegradable and eco-certified
- 🔬 Backed by extensive scientific data
- 🏆 Compliant with global regulations
- 💧 Functional across various pH levels
- 🔒 Secure when sourced from reliable GLDA raw materials manufacturers
As a result, tetrasodium glutamate diacetate market demand continues to grow among formulators who want to deliver safe, high-performance, and sustainable products.
