Sodium gluconate is a biodegradable odourless non-corrosive salt used in some cleaning and personal care products. We use this in our Dishwasher Tablets as a chelating agent to bind to metal ions and 'soften' the water, improving foaming and cleaning performance - especially in hard water.
Sodium gluconate is synthesised from gluconic acid, which can be found in nature in honey and wine - and which can be produced through fermentation of plant sugars. This high-performance ingredient is considered a low hazard and is readily biodegradable, completely breaking down within 2 - 35 days of entering the waterways.
Other names: C6H12O • Na; D-Gluconic Acid, Monosodium Salt; Sodium Gluconate (HCPA)
