I'd be really Interested in someone explaining how a surfactant helps a bleach clean, it might be basic stuff but I like to think my chemical knowledge is above average and I know how surfactants in thier many guises work, but considering bleaches are not detergents and do not remove dirt I don't see how adding them helps, bleaches don't need a wetting agent or help in holding dirt in suspension or anything else a surfactant helps with.
Does it increase chemical reaction? or hinder evaporation so the bleach has longer to work? Are we just referring to oxidising bleached or also reducing agents?
Might be worth talking to Acceptas' technical department to see what they say, they mention adding it to oxidising biocides but does this include S/H?
