Hello DataComeGuy...Last Post on this topic unless you want more yourself, as I don't want to get too off track from your original topic...
...Read the MSDS online for facts. Dr. Google can be such a fraud sometimes?...
I agree...about "Dr. Google" (sometimes) and folks should always read MSDS and Hazard Substances Fact Sheets
I think this might have been aimed at Tim (?) not sure...As stated I think mineral oil has its place as an Rx or in industry for sure...
As to MSDS and HSFS...they were (at one time) my life as they are huge in the pest control and chemistry industry...However!!!!...many can be very misleading and hard to read for lay-folk and professional alike.
Here is just an excerpt for an HSFS from New Jersey...for those interested in..."all the facts"...by all means search it out...

...I only ever used olive oil. The fatty acid chains in the triglyceride are fairly short (C16 ...
I can see that...but probably not as well as you (LOL) in the chemistry department...I'm out of practice!!!
...I never read any BS about allergic reactions...
Anaphylaxis to Olive Oils (??) I would agree is more "BS" and mistaken identification than anything...
Can it occur? Anything is possible with allergens and sensitivities, but again these would be extremely rare and its almost impossible to dial in without hospitalization and broad spectrum testing to even be certain.
With Walnut Oil, its not as rare at all, as this and related "nut allergies" often do have a more common anaphylactic response and/or sensitivities with some people on that spectrum including contact dermatitis...more common, but again with a "heat treated" pure food-grade sample I would say it gets rarer...yet...still not worth the risk in my view and experience. Any Doctors that specialize in food allergen responses would ( and have) agreed its not worth the risk with "true nut oils,"
as it moves past what we would use as woodworkers and more to do with what consumers might try if they here a "nut oil" like walnut is used and then they try to reapply a similar form oil either laden with and or contaminated with the offending proteins that cause the reaction.
Case examples of EMT responses (I'm out of that loop now) was relatively common per annum for Walnut (rarer still for Olive related) but again...was it the oil?...or a protein contaminate of some form...or...something else?
Without specific case study and testing, much of this comes to be "urban legend" not science...
...I did do a dish with straight beeswax. The pre-oven application of melted wax was a nightmare of a mess in the kitchen...Technically, the process worked exactly as effectively as predicted. Not again, I think. Waxes are long chain esters,some running C60. Too big. It works but plant oils do the job very well. ...
I can't wait to try some of the blends!!!
Any pointers for the beeswax? Thin out with food grade citrus oil and keep the temp below flash point?
Have you tried multi treatments? Oil boiling and then the oven?
I think it could be made applicable beyond just utensils for full on "Stump Blocks" but this will have to be on a more professional level and commercial-custom oven. My friend dug out the old "cauldron" that could easily hold many liters of oil and handle a proper tree stump and/or wood items for jointing a full butcher block...
Thanks again Brian for this great advise and method...very applicable to all this!!!
