Ivory soap does have fragrance, even the original. Is there a scientific reason or lore? I make soap, there are so many do's and don'ts in the soap making world that do not hold up to facts. Wow, I Make Soap As well! I have been considering making a batch of Pure Coconut Oil Soap at 0% super fat just to use for Burnishing stage. I make coconut oil soap all the time (20% superfat) and love it! I would think making any 0% superfat soap (regardless of the base oil) would be fine for this burnishing purpose? The only thing I would wonder about is being slightly off in any direction... Would a bit of un-reacted NaOH in with the rocks be ok? What about a bit of un-reacted oil/fat?

dirtsifter I am sorry but I am lost about what you said. Soap is made by reacting fats and oils with lye (sodium hydroxide for bar soap). Those fats and oils, i.e. beef tallow, lard, coconut, palm, palm kernel, olive ,soy , etc all have different types of fatty acid chains which gives the resulting soap different properties.(bubbly, foamy, cleansing, conditioning, etc) acid+base=salt. In this case, the salt is called soap My question of wonder is what type of fat/oil is used to make "pharmaceutical grade soap" I have not heard that term before. Just me wondering out loud. LOL. Fun fact: Ever see lye in a commercial bar soap list of ingredients? You won't. The ingredients label lists the fat after it has been reacted with lye so tallow becomes tallowate. If the ingredient ends with ..ate., that's a fat that has been reacted with lye. The process is called saponification. Ivory soap is little different than any other brand. Such a rabbit hole, eh? That's a great summary of how soap is made! The only thing I can think of in terms of 'pharmaceutical grade' would be using any ingredients that are listed as USP grade. USP stands for 'United States Pharmacopeia', which is a giant compendium that not only lists the basic testing requirements for performing release and stability testing of commercial drug products, but is also provides monographs for the testing and purity requirements for active pharmaceutical ingredients (API's) and excipients that will be used in the manufacture of drug products. So I imagine, if you use USP grade ingredients in your soap, you can call it 'pharmaceutical grade', though I wouldn't advise it! :-)

Any soap would be fine, I picked Coconut Oil simply because it has the highest clensing power of all the oils. I dont think most rocks would react to lye because most rocks are also alkline but I am not sure. As far as unreacted oil, I doubt it would Harm the rocks, but it is possible that they could feel slightly oily maybe depending on the superfat %.

Is the excess oils in a superfatted soap an issue? I'm allergic to anything that contains formalin (lots of liquid handsoaps contain this) and am potentially sensitive to fragrance (since companies are not required to list ingredients for fragrance) so I avoid it as much as possible. I use Dawn or a basic castile bar soap at home, and wondering if the latter would be too much oil for a tumble? I bought some borax but I don't want to kill my trees.

You might want to look into making soap, as far as hobbies go its pretty low cost to start up, all you need is 1 mold, Some Lye(you can even use Pure Lye Drain Cleaner from the hardware store, like red devil, just make sure its Pure lye) and some sort of fat or Oil. Soap calc online calculator is great just google soap calc.

Here are some less esoteric reasons: (1) it is cheap. (2) It is easier to shave off with a knife than many other bar soaps. (3) it has less perfume and "junk" than some other bar soaps. (4) it does not create a lot of suds (good thing--see "blow off the lid" below).
I used it for years for burnishing and (sometimes) cleaning between grit stages and it worked great. I still use it if I want to cushion a very soft load during all grit stages, but otherwise I use a powdered detergent formulated for babies that has a minimum of scents/noxious chemicals. But--I am now using a vibe for all stages except initial grind unless I am doing very fragile rocks, then they remain in the rotaries with a lot of cushion, and sometimes Ivory soap.
Sometimes when you are tumbling that dreaded combination of both soft and brittle, you want a thicker-than-water medium so that the rocks sort of slide around rather than banging around. Ivory Soap does it well. I've seen others swear by various syrupy mixes but have never tried them--I'm too afraid the addition of sugars or any organic matter may create a situation where the barrel will blow the lid.
