GLDA-Na4 is a 'chelating agent'.
GLDA-Na4 usually appears as an odourless white powder that is soluble in water and is used as a multi-purpose, clear, liquid chelating agent and preservative booster.
GLDA-Na4 inactivates metallic ions (charged particles) in product formulations, acting as a chelating agent.

Free-roaming iron and copper ions in formulations can lead to rapid oxidation.
Using a chelating agent helps to slow this process, allowing for the creation of products with improved stability and appearance.
GLDA-Na4 is often found in sunscreen, facial cleanser, shampoo, makeup, lotion, cleansing wipes, bar soap, and other cleaning products.
GLDA-Na4 is a high purity, versatile and readily biodegradable chelating agent based upon L-glutamic acid, a natural and renewable raw material.
Actives: 47-50%.
Excellent chelating effectiveness controlling metal-catalyzed decomposition.
Reduces water hardness and prevents precipitations.
Boosts performance of preservatives improving shelf life.
Stabilizes the pH value and is effective in a wide pH range.
Does not sensitize human skin.
Completely biodegradable as compared to phosphates and phosphonates.
Effective alternative to EDTA.
GLDA-Na4 is a liquid biodegradable chelating agent widely used in various industries, including water treatment, detergents, and personal care products.
This tetrasodium salt of the aminopolycarboxylic acid GLDA-Na4 is highly soluble in water and exhibits excellent chelating properties, making it an effective alternative to phosphates and other environmentally concerning chelants.
GLDA-Na4 is particularly useful in applications that require efficient sequestration of hard water ions like calcium and magnesium, preventing scale formation and enhancing cleaning performance.
