Tetrasodium glutamate diacetate (GLDA)
The GLDA is a powerful chelating agent made from natural, biodegradable, renewable raw materials and also functions as an effective preservative booster. The GLDA complexes hard water ions effectively whilst retaining its high chelating value at elevated temperatures compared to other chelating agents. It can be used as a more sustainable alternative to phosphonates and commonly used chelating agents (NTA and EDTA) in a wide number of applications.
Produced from a naturally occurring amino acid, the GLDA is readily biodegradable with a high level of solubility over a wide pH range and is thus a greener alternative to many other chelates. The GLDA can be used to replace EDTA in a 1:1 ratio in many applications and products. It also does not sensitise human skin and provides enhanced biocidal/preservative boosting power when compared to commonly used boosters such as EDTA and NTA.
It can be used in many applications such as industrial and household cleaners for improving the detergency. The GLDA when added to a formulation can help stabilise the product and prevent discoloration. In larger quantities it will enhance the cleaning ability and prevent deactivation of active ingredients during use. It also reduces the effect of Calcium and Magnesium ions resulting in better surfactant performance. It is suitable to be used in personal care and cosmetics products, due to the strong chelating ability of calcium and transition metal ions prolonging the shelf life of many products.
