I want to make a soap specifically for laundry (and possibly other household uses). Would you do 100% coconut with no super fat? Or still add in a few other oils. I looked at the numbers on soap calc for a 50% coconut, 30% olive, and 20% crisp and the cleansing was above the recommended range. I am assuming the range is for skin use only. I don't want my clothes to wear out prematurely due to the soap. Ideas?
