Tetrasodium Glutamate Diacetate (TSGD) – Eco-Friendly Chelating Agent

Tetrasodium Glutamate Diacetate (TSGD)

Biodegradable chelating agent for enhanced stability, clarity, and preservative efficiency.

INCI: Tetrasodium Glutamate Diacetate.

Appearance: Clear to slightly hazy colorless to pale yellow liquid.

Solubility: Fully water-soluble.

Typical Use Level: 0.05–0.30% (as supplied).

Tetrasodium Glutamate Diacetate (TSGD) is a high-purity, biodegradable chelating agent derived from L-glutamic acid. It complexes trace metal ions such as calcium, magnesium, and iron, helping to improve formulation stability. By limiting metal-catalyzed oxidation and degradation, it supports product clarity, color integrity, and preservative system performance.

What It Does

Tetrasodium Glutamate Diacetate (TSGD) is a high-performance liquid chelating agent designed to improve formulation stability and shelf life while simplifying processing.

Trace metals present in water, clays, plant extracts, and other raw materials can accelerate oxidation, discoloration, and ingredient breakdown. TSGD neutralizes these effects by binding metal ions, helping maintain formula integrity, appearance, and effectiveness over time.

Key Benefits

• Improves overall formulation stability and shelf life.
• Reduces oxidation, discoloration, and degradation.
• Enhances preservative system performance.
• Supports improved clarity and consistency.
• Biodegradable and more sustainable alternative to EDTA.
• Easy-to-use liquid format eliminates dissolution step.

Suggested Use Levels

• 0.05–0.10% for standard formulations.
• 0.10–0.20% for active-rich systems.
• 0.20–0.30% for complex or instability-prone formulations.

Ideal Applications

• Serums and treatment products
• Cleansers and toners
• Emulsions and creams
• Hair care formulations
• Botanical and active-heavy systems
• Preservative-sensitive formulas

Formulation Notes

• Add directly to the water phase during formulation.
• No pre-dissolution required due to liquid format.
• Compatible with most cosmetic systems.
• Effective across a wide pH range (~3–10).
• Can replace or reduce EDTA in many formulations.

Yes, it’s easier than the powder version. No, that doesn’t mean you get to skip stability testing.
