Redex

[K2-K6]

Why would they need to omit anything from their data sheets?

They supply into an unregulated market that has neither standards or any realistic consequences.  Also no real prospect of anything like a warranty claim against them.   To questions like "I used your product in my 55 million mile Toyota Camri 1992,  it didn't provide a measurable improvement in running or economy. Could it be your product is not fit for purpose?" Well although we are surprised to hear of your negative experience with our fine product, it's most likely that something else has an overriding influence that affected the outcome. Here's a free tin to help with your next project.

They'd hardly want to get caught up in legal position by not having anything that falls into controlled substance area not disclosed from a long term liability point of view.  They can just point and say you all know what's in there,  it's up to you to take any precautions relevant to your circumstances.

The only mystery is how they get so much money for it.

Simply because they can. If a ingredient is not a hazard or health problem then it doesn't need to be listed and even then it depends on the substance and what % of the total product it is. Some SDS are not worth the paper they are printed on.  Mainly it would remove the mystery in MMO and WD40 and the likes.
They all like their little secrets its what they trade on. For years people have believed its fish oil in WD40, makes a change from snake oil but you are right it is mineral oil that's in it.. I worked for years for the company that makes WD40 in this country.

Which is why I dont get too hung up on variety of redex, just getting it as cheap as possible. A lot of folk say it's basically the same additives they add to premium fuels, could well be right on that, I know on my rebel 125 it ran far worse on Trsco fuel, than on Texaco stuff, on that the difference could be felt within about 1/4 mile of the filling station and was about 10 or 15mph off the top speed and a lot of acceleration. The Texaco stations been around years and is a small village garage so liklyhood should be they'd be the old tanks and stale fuel risk, on paper, Tesco store was pretty well new site at the time so should be clean tanks, fresh fuel. Whether its additives left out or ethanol added there was a marked difference.
When it comes to the various releasing fluids or oils, seems a very murky world, I buy cheapest as a rule, used gallons of duck oil wd40, 151 super maintenance oil etc. The aerosol is handy to get stuff into the right spot and not coat the car in more old oil, but for serious workshop jobs with properly rusted up stuff old engine oil or heat seem as effective as any fancy fluids. That and time, in fact wd40 and the thinner oils dry out where used engine oil keeps soaking in. Add a brass hammer and time most things go before the hot spanner is applied. A lot depends on the job. Really old machines using cast iron and imperial threads seem to revive and un seize better than 80s metric stuff. I revived a 100 year old lathe seized solid since the 50's in a day using 151 releasing oil and 2 stroke oil without a single dammaged thread before chistmas, yet a 100 year old hay rake refused to free off its axle so stubbornly I had to drill / cut the whole axle assembly out of the wheel. Gas axe seemed unable to shift it with heat or cutting. None of the releasing oils even got close to wetting the joint, even applied hot, soaked for a week etc. When I drifted the split stub of much abused, drilled and cut axle out of the hub the joint was dry as could be despite all the penetrating fluids thrown over it.

To be fair to WD (I know I included that one on this thread) it does do basically what it says,  but has never made miracle claims as far as I'm aware.  Probably kept more British car HT systems going over the years than any other too.
They make a bit of a thing about it being secret formula etc along with stories of how it came about,  but no real problem with that.

As Matt illustrated above,  the general problem is to get a solvent to penetrate whatever is stuck and take the oil of choice with it to attempt some form of action.

Fuel treatment performance claims for additives seam mostly to be based on solvent to remove gum, if it does that.  Maybe some sort of oil to lubricate. Then something to improve octane rating,  funnily enough methanol / ethanol and toluene appear in many.  The first two are things people are trying to avoid in fuel,  but put a performance label on them in a special bottle and it goes from enemy to friend unbeknown to the purchaser. Great irony.
