GLDA-Na4 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.GLDA-Na4 is NTA free and also functions great as a preservative booster.
GLDA-Na4 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 GLDA-Na4 facilitate the removal of metal ions from soils leading to a greatly improved cleaning performance.
GLDA-Na4 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 GLDA-Na4 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.
GLDA-Na4 can replace EDTA 1:1 and can be used in cosmetics and personal care products as well as HI&I products.
