Beschreibung
Zusammenfassung:	A warewashing detergent composition is provided for use for in cleaning of alkaline sensitive metals such as aluminum or aluminum containing alloys. The compositions include alternatives to sodium tripolyphosphate and/or other phosphorus containing raw materials, while retaining cleaning performance and corrosion prevention. According to the invention, a phosphinosuccinate oligomer of mixture thereof is used as a corrosion inhibitor and can be included for aluminum protection in a number of different detergent compositions. L'invention concerne une composition détergente de nettoyage destinée à être utilisée dans le nettoyage de métaux sensibles aux alcalins tels que l'aluminium ou des alliages contenant de l'aluminium. Les compositions comprennent des alternatives au tripolyphosphate de sodium et/ou à d'autres matières premières contenant du phosphore, tout en préservant une efficacité de nettoyage et une prévention de la corrosion. Selon l'invention, un oligomère de phosphinosuccinate ou un mélange de ce dernier est utilisé comme inhibiteur de la corrosion et peut être compris pour la protection de l'aluminium dans de nombreuses compositions détergentes différentes.
