Since Sodium Percarbonate has a greater rate of dissolution, has a more environment-friendly profile and has the advantage of concurrently generating hydrogen peroxide and of liberating carbonate, which gives a higher pH than borate and favours perhydrolysis, percarbonate today is the form of hydrogen peroxide of choice in most European detergents.
Peracids and peracid precursors are a second category of organisms that bleach materials. The kinetics of bleaching with persalts are too slow to be suitable for usage in more cost-effective wash cycles, which entail temperatures below roughly 60°C, necessitating the addition of peracid precursors (also known as bleach activators) to the formulation. These species combine with persalt to form a more potent oxidising species, usually a peracid anion, which is a percarboxylic acid with the functional group -OOH.
