The L form of Tetrasodium glutamate diacetate, or GLDA, is based on renewable materials (fermented sugar), functions across a wider pH range, matches or exceeds EDTA in controlling soap scum and is readily biodegradeable.
(It is also being researched for use as a micronutrient)
GLDA is free from genetically modified raw materials and is not irritating to skin or eyes. It is suitable to be used in personal care and cosmetics
GLDA is a greener alternative, as it is predominately made from sugar waste material. The environmental impact (according to ISO 14040) of all strong complexing builders was measured and GLDA has the smallest ecological footprint.
