Abstract

A peracid bleaching species is formed in situ in aqueous wash liquor by reaction of a peroxygen bleach precursor, such as perborate or percarbonate, and a bleach activator. The bleach activator is an acetylated ethylene diamine, that comprises at least 25% triacetyl ethylene diamine. The peracid is formed more rapidly even at low temperatures (F2) compared to use of conventional pure tetracetyl ethylene diamine (F1) and better disinfectant properties result.
