BioPure™ GLDA

Tetrasodium Glutamate Diacetate
AKA: L-Glutamic Acid, N-N Diacetic acid tetra sodium salt
CAS:51981-21-6 EINECS:257-73-7

Biopure™ GLDA is a powerful chelating agent made from natural, biodegradable, renewable raw materials. It exhibits excellent metal chelation properties, high water solubility, stability over a wide pH range, and low ecotoxicity. Biopure™ GLDA is NTA free and also functions great as a preservative booster.

Biopure™ GLDA bonds with metal ions in the water supply to prevent scale formation. Soils form complexes with metal ions and bond to surfaces. These bonds make cleaning and removing these soil-metal complexes difficult. The strong chelating and dispersion properties of Biopure™ GLDA facilitate the removal of metal ions from soils leading to a greatly improved cleaning performance.

Biopure™ GLDA dispersion properties also keep soils suspended in the wash and rinse water, stopping re-deposition of the soil onto cleaned surfaces and insures easy rinsing in applications such as dishwashing. Small quantities of Biopure™ GLDA added to formulation can help stabilize the product and prevent discoloration. Larger quantities will enhance cleaning ability and prevent deactivation of active ingredients during use. It also reduces the effect of Ca2+ and Mg2+ ions resulting in better surfactant performance.

Biopure™ GLDA can replace EDTA 1:1 and can be used in cosmetics and personal care products as well as HI&I products.
