Abstract

NabionTM is an all-in-one and eco-friendly builder. It is a fully water-soluble mineral powder composed of white granules made from sodium carbonate and sodium silicate. We carried out a study to compare the capacity of sequestration of calcium and magnesium ions between sodium citrate, NabionTM 15 and NabionTM 26. We found that NabionTM is an efficient alternative to sodium citrate for sequestering calcium and magnesium ions.

NabionTM is an all-in-one and eco-friendly builder produced by Novabion (part of Humens group). It is a fully water-soluble mineral powder composed of white granules made from sodium carbonate and sodium silicate. It complies with the Ecocert standard for eco-detergents. Nabion™ product range was developed for laundry and automatic dishwashing detergents (powder formulations). The range of NabionTM contains two references: NabionTM 15 and NabionTM 26 (depending on the percentage of sodium carbonate).

Its main advantages are: source of alkalinity with a buffer effect, fully, high and quick solubility, reduction of incrustation and high capacity of sequestration of calcium and magnesium ions. Our study focuses on this last property.

Calcium and magnesium ions, naturally present in tap water, are essential for life but are harmful for an efficient washing. Theses ions are responsible for graying on laundry, spotting and filming on dishes but also reducing the performance of surfactants, it is strongly recommended to contain them to limit these negative effects as much as possible.
