Wow, nice work, and welcome to the
addiction relaxing hobby.
May I make a few suggestions? Save the expensive oils (fractionated CO, jojoba, argan) for leave-on products. Soap is not on the skin very long before it's washed down the drain.
FWIW, I have very sensitive skin, and my husband has psoriasis and eczema. What's best for both of us, as well as many others with sensitive skin, is to keep the cleansing oils quite low, usually less than 20%. That includes coconut oil, babassu oil, and palm kernel oil. While they may be nice in raw form, when they are saponified, they become very drying and potentially irritating, especially for psoriasis. When you do use coconut oil, definitely melt it first, unless you are using the heat transfer method. But don't use fractionated CO - it doesn't make nice soap, and needlessly increases the cost.
A lot of people don't realize that the "cleansing" number in the soap calcs really refers to "stripping all the oils off your skin." For sensitive skin, you want that cleansing number really low, even below the minimum suggested by the calc. Soap with a cleansing value of 0 will still get you clean. If you are open to using animal fats, lard and tallow make wonderful, gentle soap that is much easier on skin than coconut oil. Maybe try something like this:
45% lard, tallow, or blend of the two
20% soft oil of choice
20% CO, PKO, or blend
10% butter (cocoa, shea)
5% castor
With all those low-cleansing, high conditioning oils/fats/butters, you will have a very gentle soap with a creamy lather, even with a low superfat of 2-3%. If you want bigger bubbles, you can achieve that by dissolving some sugar in your water before you add the lye. It doesn't change the numbers in the soap calc, but it will definitely give you more bubbles.
Good luck, and I look forward to seeing what you make next!
EDIT: you don't need to grease silicone molds, or molds lined with freezer paper.
