Lard and tallow were some of the first soaps I ever made, and they continue to be favorites with family and friends. I even use them in liquid soap. When I was first starting out in this addictive hobby, I had the very good fortune to be on a soaping forum where I learned that Oakmoss covered the odor of tallow and lard in soap. It works! And it doesn't take much to work. TIP: Oakmoss Absolute is pricey, and tricky to work with so I dilute it in jojoba oil (long shelf life) to make it user-friendly and easy to measure. METHOD First warm the absolute by setting the bottle in a glass of hot water until it swirls easily. I warm the jojoba in the microwave in a 2-cup Pyrex to about 100°F (38°C). To create a 10% dilution, I add 1 oz. Oakmoss to 9 oz. jojoba and gently stir for one full minute to get it completely incorporated. Allow to cool before pouring into an dark colored glass bottle. I store it with the rest of my supplies in a box on a shelf in my soaping cabinet. Use 0.7% (1/4 - 1/2 tsp. PPO) Oakmoss is a wonderful blender and fixative to anchor EO blends. I haven't checked in a while, but you may find it in the 10% diluted form. Not sure. You can also try an FO if you find it. I've never used FO, so I can't say if that will work or not.
