TAED pure – percarbonate activator, completely biodegradable 500g format plastic-free packaging in compostable Naturflex and FSC box, hand-packed made in Italy HOW TO USE Add one part of TAED to two parts of percarbonate to activate the percarbonate even in cold water. Essential if you use percarbonate at low temperatures, as it activates only above 50 degrees on its own. Tip: you can mix 10g of TAED with 20g of percarbonate each time to add to your laundry at low temperature, while using pure percarbonate if washing at 60 degrees. Also perfect for sanitizing toilets or sponges and brushes! Fun fact: our TAED is white, but you may have found colored ones on the market (usually blue or green). The dye is added to 'show' that there is TAED in the preparations, but it actually has no other utility. From a minimalist perspective, it seems really unnecessary to 'color' a pure product.
