Abstract
Abstract Peracylated aliphatic polyamines are useful as activators for inorganic peroxo compounds, i.e., they set free the available oxygen of the peroxo compounds in aqueous solutions at temperatures below 80°C and are thus useful as additives to detergents especially inasmuch as they are compatible with usual detergent brighteners.
