With the exception of shampoo bars, I have decided not to use castor oil in my soaps anymore. I still have soaps left with it, but my new recipes won't have any. I realized I prefer the creaminess of my soaps without it.
My goal when choosing oils is to try to buy locally first. It's just so nice to be able to drive somewhere and pick up a gallon of oil and make soap with it right away. I still have to order most of my oils, but at least I can find olive and rice bran oil locally.
My lavender martini twist soap was made with pomace olive oil, rice bran oil, organic/sustainable palm oil, and coconut oil. I also added about 0.5 oz ppo nonfat greek yogurt. The soap behaved beautifully, but silly me let it overheat a little in the mold. It was softer than my usual recipes so I am going to add some shea butter back in. I realized that having a little butter in there always seems to help with the hardness as well as creating a milder bar of soap. I am going to skip the yogurt for this next batch and add 1 or 2% sodium lactate back in. I love that stuff! I went with one of my favorite designs, an in the pot swirl (ITPS).
Here's the making of it video too!
