Also, to add to other people's points; newborns/infants should have their clothes washed in non-bio, it's less likely to cause irritation to their skin, conversely it's not as effective due to lack of (biological) enzymes, particularly at lower temperatures, so you should be using regular "bio" most of the time. Also, competition. If you're happy to pay 10 times more for Colour, Dark and White powders because nobody else makes it, that's your choice, we'll just put it on the shelf next to the rest of the more affordable options.
