This must be one of the oddest slip-ups so far... I have eczema on my hands and so I try to be careful what cleaning products I use. I bought some Ecover washing up liquid the other week, a great big bottle of it, and was idly reading the back when I happened to look down at the ingredients list. The washing up liquid that apparently cares about the environment and my skin contains...milk whey. Milk whey! In washing up liquid! WTF?!
