Abstract
Solid activator bodies for activating oxygen-based bleach at relatively low temperatures are provided which preferably include respective quantities of tetra acetyl ethylene diamine (TAED), phosphate sequestering agent, non-phosphate solidifying agent, surfactant and water. The activator bodies are readily dispersable in hot water to form dilute dispersions which can be added directly to cleaning equipment along with oxygen-based bleach. The activator enhances bleaching effectiveness and generates peracetic acid, a potential antimicrobial.
