| Résumé : |
The demands of high performance cleaning especially in high electrolyte cleaning products can require uncommon surfactant properties to be effective in both consumer household and industrial and institutional (1+1) applications. In particular, highly alkaline formulations are shown to be most effective for removal of stubborn greasy or burnt on stains. However, such alkalinity also destabilizes many common surfactants, making the formulation of concentrated alkaline cleaners challenging; a problem similarly faced where high chelating agent loads are desired. We present findings from the development of two cleaner ingredients — Berol LFG 61 and Berol DGR 81 which have very different behaviours in use that can provide formulation performance-enhancement to many challenging applications. In this article, we will show these products deliver excellent performance in high caustic soda or chelating agent formulations — with one providing medium/high foaming, and the other very low/no foaming. We will provide framework formulations and performance-in-use data for a variety of representative application conditions to exemplify this behaviour. These high-activity ingredients are also mild, with excellent environmental properties which are compliant with EU Ecolabel standards. |
