If you make any more soap with the high percentage of canola, you might want to add some stuffs to prevent rancidity (aka your soap smells gross after a while or changes colors) right at trace -- vit. e oil, tumeric, cinnamon, chocolate, and coffee all have antioxidants and you're likely to have them at home already!
Not sure on the amounts, but I don't think you need to have a lot -- just make sure it's mixed in well.
