Do synthetic oils oxidize?
After a lot of doubts I finally ordered several synthetic oils: Mineral Oil, Petrolatum and Hydrogenated Polyisobutene.
I have some experience with vegetable oils, but I don’t know whether synthetic oils are the same. Every time I search for synthetic oils online, to understand how to formulate with them, I either get chemo phobic articles (like 10 reasons to avoid mineral oil etc.) or articles about car engines.
Should I add vitamin E to the formula (let’s say a basic o/w moisturiser), or they don’t oxidize (I understand it sounds silly for professional chemists, but I really can’t find anything reasonable online)? Any other specifics related to synthetic oils?
Thank you in advance.
