Sorry do run close, I tune my own stuff, and spent years in shops, I do find them obnoxiously close but can generally keep them from rubbing. As good as I've seen from any MTB news source. In this case mineral oil not have as high a boiling point. To me personally, I don't care about the whole DOT vs mineral debate, it's just funny when marketers get into the game of playing bullet point maker for Pro's and Con's and list things a that are unrealistic as the con's of something. Every thing in mechanics has trade offs, doesn't matter what subject. smooth and creamy peanut butter can be used as hydraulic oil, but it ain't great for hand fatigue! or a bunch of other parameters you mentioned. The lack of a specific standard is also why brands will void warranties if you use fluids outside if what they specify. Since it's not standardized, we don't know for sure. The mineral oil itself may not be an issue, but additives could be an irritant.

It's most likely safe for skin contact, but unless they come out and say it is, it's better to be safe and take precautions. Point being, mineral oil in baby oil being safe doesn't mean it's the same substance/makeup as what is in mineral oil for brakes, which is not standardized. Those aren't the fluids in use here, though. AFAIK (and the Shimano sheet confirms), it's not 100% mineral oil and does contain some additives. AFAIK there isn't any specific standard for what mineral oil brake fluid contains aside from some unknown quantity of mineral oil and other unknown quantities of unknown additives. The issue with mineral oil, compared to DOT, is the lack of standardization, though. If Magura and Shimano can make mineral oil brakes that have more stopping power than SRAMs, What's with the claim that mineral oil isn't for 'performance' users? Shimano publishes a safety data sheet that more or less says it's not harmful for skin contact. SRAM even mentions those tests in their own video (which fails to mention they get outshined by other companies using mineral oil). The MT7 performance isn't even subjective, go look at the Enduro Magazine tests results where they use a lathe test bed to get braking force/heat/stopping comparisons. Also, despite SRAMs video, DOT fluid does suck worse if you get it on your hands than Mineral oil (wear gloves kids). After and entire year of shuttles and bike park, barely any contamination during the bleed. I am never going back, lighter lever feel, noticeably more power, never get bite point bubbles that I need to bleed (looking at you SRAM and Shimano). MT5's are relatively cheap for what you get as well, simple pad swap and they are basically MT7's. I've convinced my friends to get on the MT5 bandwagon as well (because I am their mechanic). I had run codes since the first gen, and they are great brakes, however, the last 3 seasons I have been running Magura MT7's. (they are the ONLY manufacturer that did SCIENCE, lol) SRAM did imply that performance wise mineral is inferior, but maintenance wise mineral was superior in that video.

Code brakes will still remain the higher end option, with less seal friction and a higher range of operating temperatures due to the use of DOT fluid. The lever feel is said to be similar, although the DB8 brakes do have 10% less power than the Codes. The DB8 brake has a similar caliper design to SRAM's Code brakes, and they also use Code pads. They also use Maxima's mineral oil, which is green, instead of the yellow DOT fluid. To avoid any possible contamination, the DB8 brakes use an entirely different bleed kit than SRAM's DOT fluid brakes. That service interval is extended to once every two years for the new DB8 brakes, which will be welcome news for riders who'd rather, well, ride, instead of spending time wrenching, and for newcomers to the sport who are still developing their bike maintenance skills. With their DOT brakes, SRAM recommends bleeding them at least once a year. The goal for the DB8 brakes was to create a very low maintenance option, a brake that can be used for more than one season without requiring a bleed. Why mineral oil? After all, every other brake in SRAM's lineup uses DOT fluid, and they've long touted that fluid's benefits.

When they do finally hit store shelves, they'll be priced at $137 per wheel. The DB8 brake will initially be showing up on complete bikes sometime in the near future, but at the moment there's no definitive timeline for when they'll be available aftermarket. SRAM has a new brake on the way, one that uses mineral oil rather than DOT fluid to activate its four pistons.
