What would be a good laundry detergent for me and my sensitive skin?

All of the laundry detergents I have tried lately have really irritated my skin even ones that say they are made for sensitive skin (like Tide Free for Sensitive Skin). I am allergic to coconuts and nuts (also mushrooms but I doubt that affects detergent) and laundry detergent enzymes seem to practically eat my skin (which I believe is why Tide doesn't work for me). I am not sure why, but any concentrated detergent I have used has been even worse. I am tired of cloths making me itch like crazy and the only environmentally friendly, enzyme free, supposedly hypo-allergenic detergents I have found have some sort of coconut derived product in them. Please help! I'm going bananas!
