Making Soap

[quote=maceves]Too much lye and you will have a caustic soap that can only be used for laundry.

Is there a specific recipe for laundry detergent or should we just add more lye? A while back I had the opportunity to get my hands on a five-gallon pail of laundry detergent from Ecolab that was, according to My Dear Sweet Boss, the best detergent she ever used. But alas, my soap pimp tells me that was a one-time deal. He also explained that the reason it works so well is that it has a higher level of caustic than retail products, which is also why it is so strictly controlled for safety reasons.
Sure would like to be able to make my own if possible.
