Abstract (en)
The present invention provides a multifunctional machine dishwash detergent composition being essentially free of phosphates and comprising: a) at most 10 wt% of surfactant; b) from 5 to 70 wt% of an amino polycarboxylic compound; c) from 5 to 40 wt% of citrate; d) from 0.05 to 3 wt% of a water soluble bismuth salt; e) from 0 to 5 wt% silicate; wherein the amount of citrate is from 30 to 70 wt% on the total weight of citrate and amino polycarboxylic compound. It was surprisingly found that this composition provides a good alternative to phosphate builders and shows good cleaning and glass care performance.
