Im going to make my first batch of soap with all lard. I have a small bottle of orange essential oil sitting in my cabnet. I use it to scent my homemade laundry detergent. Its from now foods and says on the bottle to if i want to use it for anything other than aromatherapy to dilute with a carrier oil. Well i want to add it to my first batch of soap and im wonder how much i should use ppo. Do yall have any advice? I also have peppermint and lavender. Would any combo of the three smell good? I am not very good at figuring out what scents smell good together! Thanks!
