Its full name is a mouthful: tetrasodium glutamate diacetate. Its friends call it GLDA.
Quick answer: GLDA is a chelating agent. It grabs the minerals in hard water so the surfactants can do their job. It's in Just 9 to help with tougher water and tougher loads.†
What chelating means
Hard water has calcium and magnesium. Those minerals get in the way of cleaning. A chelator holds onto them so they don't.†
Think of it as a bouncer for minerals.
