Abstract
The invention relates to a method for sequestering metal ions at a low pH. Surprisingly, it has been found that certain fructan polycarboxylic acids, as opposed to the generally used sequestering agents, are capable of complexing metal ions in an efficient manner at a pH lower than 6. Additionally, the invention relates to a cleaning composition containing a fructan polycarboxylic acid as sequestering agent.
