The 3 'eco' washing powder brands I have tried :
Ecover : I felt it didn't wash the clothes to even a minimal acceptable standard.
Surcare : ok. Nothing of note
Simply Pure : I 'feel' this is the best of the 3.
Recently I tried 'Simply Pure' washing powder for the first time. I feel this gives the best wash of the 3 'eco' brands I have tried. I would say it may even be better than the normal 'harsh' brands of washing powder. With 'ecover', I felt it did not even wash the clothes to what I would regard a minimum standard (just my unscientific opinion). Surcare seemed average at best. So for me, I am so far impressed with 'Simply Pure'. I have used both the tabs and the powder.
So my current 'best' of the 'skin sensitive' brands of clothes-washing detergents is Simply Pure

Update Nov13 :
It looks like Asda and Tesco no longer stock the powder. The tabs still seem available in Tesco
