What Is MGDA 40%?
MGDA 40% Solution (Methylglycine Diacetic Acid, Trisodium Salt) is a liquid-grade biodegradable chelating agent supplied as an approximately 40% active aqueous solution. It functions by forming stable, water-soluble 1:1 complexes with polyvalent metal ions including calcium, magnesium, iron, copper, zinc, and manganese across a broad effective pH range of 2 to 13.5. Its liquid form allows direct dosing into formulation systems without pre-dissolution, making it the preferred grade for large-scale liquid detergent, cleaning product, and personal care manufacturing operations.
Classified as readily biodegradable under OECD 301B with greater than 60% degradation within 28 days, MGDA 40% Solution is EU Ecolabel compliant and serves as a sustainable, phosphorus-free alternative to persistent chelating agents such as EDTA, DTPA, and phosphonate-based builders. Its compatibility with surfactants, enzymes, and peroxide bleaching systems makes it a versatile and efficient chelating solution for modern liquid formulation systems.
Key Functions
MGDA 40% Solution delivers multiple functional benefits in liquid detergent, cleaning, and personal care formulation systems, providing effective metal ion sequestration, hard water control, and formulation stabilization across a wide range of pH conditions and application environments.
- Metal Ion Chelation and Sequestration
Forms stable 1:1 water-soluble complexes with polyvalent metal ions including calcium, magnesium, iron, copper, zinc, and manganese, preventing their interference with surfactant performance and formulation stability. - Hard Water Softening and Scale Prevention
Effectively sequesters calcium and magnesium ions in hard water, preventing the formation of insoluble calcium soaps, mineral scale, and soap scum deposits on surfaces, fabrics, and equipment. - Direct Liquid Dosing Convenience
Supplied as a ready-to-use aqueous solution, it can be incorporated directly into liquid formulation systems without pre-dissolution or additional processing steps, simplifying manufacturing workflows. - Broad pH and Temperature Stability
Maintains strong chelation efficiency across a wide pH range from 2 to 13.5 and remains thermally stable at elevated temperatures, making it suitable for both acidic and alkaline cleaning formulation systems. - Peroxide Bleach Stabilization
Chelates iron, copper, and manganese ions that catalyze the rapid decomposition of peroxide bleaching agents, helping to preserve bleach stability and cleaning performance throughout the product lifecycle. - Surfactant Performance Enhancement
Prevents deactivation of surfactants by hard water metal ions, improving overall detergency and cleaning efficiency in liquid detergent systems across a range of washing temperatures. - Readily Biodegradable Environmental Profile
Classified as readily biodegradable under OECD 301B, phosphorus-free, and compliant with EU Ecolabel requirements for detergents, providing a sustainable replacement for EDTA, DTPA, and phosphonate-based chelating agents.
Applications
MGDA 40% Solution is widely used across home care, industrial and institutional cleaning, water treatment, and personal care industries due to its direct dosing convenience, high chelation efficiency, and compliance with major international environmental and regulatory standards.
- Liquid Laundry Detergents
Used as a phosphate-free builder in liquid laundry detergent systems to improve detergency in hard water, prevent calcium soap deposition on fabrics, and enhance surfactant performance across washing temperatures. - Automatic Dishwashing Detergents
Applied in liquid automatic dishwashing formulations to prevent filming, spotting, and mineral deposits on glassware and tableware in hard water conditions. - Hard Surface and Household Cleaners
Incorporated into liquid hard surface cleaners, bathroom descalers, and multi-purpose household cleaning products to dissolve existing mineral scale and prevent new deposits from forming. - Industrial and Institutional Cleaning
Applied in CIP systems and industrial liquid cleaning formulations to remove calcium carbonate, phosphate scale, and soap scum from processing equipment, pipelines, and water circulation systems. - Water Treatment and Scale Inhibition
Functions as a scale inhibitor and water softening agent in reverse osmosis systems, cooling towers, and boiler feed water applications. - Textile Processing Auxiliaries
Used in textile pretreatment and dyeing processes to sequester heavy metal ions that would otherwise interfere with dye uptake and shade development during processing. - Personal Care and Cosmetic Formulations
Used at low concentrations in cosmetic and personal care products to stabilize formulations, prevent metal-induced discolouration, and function as a preservative booster by chelating trace metal ions.

FAQs
How does MGDA compare to EDTA and DTPA as a chelating agent in liquid detergent formulations?
MGDA is readily biodegradable under OECD 301B (>60% in 28 days), while EDTA and DTPA show poor biodegradability under the same conditions. MGDA is EU Ecolabel compliant and does not carry the regulatory restrictions associated with EDTA and NTA. It maintains effective chelation across pH 2–13.5 and at elevated temperatures, making it a technically capable and environmentally compliant alternative for most liquid cleaning and detergent applications.
Is MGDA 40% Solution compatible with peroxide bleaching systems and enzyme-based detergent formulations?
Yes. MGDA stabilizes peroxide bleaching agents such as sodium percarbonate and sodium perborate by chelating the iron, copper, and manganese ions that would otherwise catalyze their premature decomposition. It is also compatible with common detergent enzymes including protease, amylase, and lipase, and does not interfere with their activity under standard formulation conditions.
What is the recommended use level of MGDA 40% Solution across different application categories?
In liquid laundry detergents and automatic dishwashing formulations, MGDA 40% Solution is typically used at 2%–5% active content. In industrial CIP and descaling systems, higher concentrations may apply depending on scale severity. In personal care and cosmetic formulations, 0.1%–0.2% active is generally sufficient as a stabilizer and preservative booster. Application-specific trials are recommended to confirm the optimal dosage for each formulation system.
What regulatory and environmental standards does MGDA 40% Solution support for finished product certification?
MGDA is readily biodegradable (OECD 301B), REACH registered, phosphorus-free, and compliant with EU Ecolabel criteria for detergents, which prohibit EDTA and NTA. It does not carry the carcinogen classification associated with NTA. Buyers should verify that the complete formulation meets all applicable certification requirements for their specific product category and target market.
What is the difference between MGDA 40% Solution and MGDA 85% Solid, and which grade is more suitable for my application?
MGDA 40% Solution is a liquid-grade product that can be dosed directly into liquid formulation systems without pre-dissolution, making it the preferred choice for liquid detergent, liquid cleaner, and personal care manufacturing. MGDA 85% Solid is a high-concentration powder grade better suited for solid formulations such as powder detergents, dishwashing tablets, and concentrated solid cleaning products. Both grades deliver equivalent chelation performance on an active content basis.
