The soapcalc default is half an ounce per pound of oil, but that does NOT indicate safe usage rates.
Essential oils and fragrance oils have usage rates that are considered "safe" based on their components. Some fragrance oils are not skin safe at all and can only be used for candles or home fragrancing, some are safe for skin but only in very small amounts, and some are safe at higher rates than you would probably ever need.
Same with essential oils. Some can be used "neat" or full strength, some can only be used in very small amounts, and some are just not a good idea for use on skin at all.
Clove oil contains strong irritants and should not be used at a rate any higher than zero point five percent, one half of one percent, so less than one-sixth of the amount soapcalc defaults to.
Please please PLEASE everyone, check with your supplier for safe usage rates! If they do not list them on their website, email them and request it. If you cannot safely determine the correct maximum usage rates, LEAVE IT OUT. I would not put something that I do not know for certain is edible in my food, I will not put something I don't know for certain is skin safe into my B&B products! Oh, and being able to eat it doesn't make it safe to use on skin, either.
Okay, stepping off soapbox now...
