My DH is very sensitive to detergents. The Tide free and clear still made him break out and itch. I have used Wisk for a while and did wonder why I could not find it. I also use Arm and Hammer free and clear. DH recently bought the 7th generation detergent because he read that is was good for sensitive skin. I am not sure anything cleans as good as Tide sadly.
I did buy a liquid to add that supposedly softens the water and makes your detergent more effective.
