I am planning on infusing natural herbs / spices etc to use as a colourant in my soaps but I don't know how much I should use. Is there a rule of thumb with these things like so much per pound of soap or so much per ml of oil? Because things like cloves, cinnamon, paprika etc can be irritants to the skin, I don't want ruin my soaps by using too much. Any ideas? What do you do?
